This family contains pepsin like aspartic proteases from plants including Chloroplast Nucleoids DNA-binding Protease and Nucellin. Chloroplast Nucleoids DNA-binding Protease catalyzes the degradation of ribulose-1 5-bisphosphate carboxylase/oxygenase (Rubisco) in senescent leaves of tobacco and Nucellins are important regulators of nucellar cell's progressive degradation after ovule fertilization. Structurally aspartic proteases are bilobal enzymes each lobe contributing a catalytic Asp residue with an extended active site cleft localized between the two lobes of the molecule. The N- and C-terminal domains although structurally related by a 2-fold axis have only limited sequence homology except the vicinity of the active site. This suggests that the enzymes evolved by an ancient duplication event. The enzymes specifically cleave bonds in peptides which have at least six residues in length with hydrophobic residues in both the P1 and P1' positions. The active site is located at the groove formed by the two lobes with an extended loop projecting over the cleft to form an 11-residue flap which encloses substrates and inhibitors in the active site. Specificity is determined by nearest-neighbor hydrophobic residues surrounding the catalytic aspartates and by three residues in the flap. The enzymes are mostly secreted from cells as inactive proenzymes that activate autocatalytically at acidic pH.

Chloroplast Nucleoids DNA-binding Protease catalyzes the degradation of ribulose-1 5-bisphosphate carboxylase/oxygenase (Rubisco) in senescent leaves of tobacco. Antisense tobacco with reduced amount of CND41 maintained green leaves and constant protein levels especially Rubisco. CND41 has DNA-binding as well as aspartic protease activities. The pepsin-like aspartic protease domain is located at the C-terminus of the protein. The enzyme is characterized by having two aspartic protease catalytic site motifs the Asp-Thr-Gly-Ser in the N-terminal and Asp-Ser-Gly-Ser in the C-terminal region. Aspartic proteases are bilobal enzymes each lobe contributing a catalytic Asp residue with an extended active site cleft localized between the two lobes of the molecule. One lobe may be evolved from the other through ancient gene-duplication event. This family of aspartate proteases is classified by MEROPS as the peptidase family A1 (pepsin A clan AA).

Pepsin-like aspartic proteases are found in mammals plants fungi and bacteria. These well known and extensively characterized enzymes include pepsins chymosin renin cathepsins and fungal aspartic proteases. Several have long been known to be medically (renin cathepsin D and E pepsin) or commercially (chymosin) important. Structurally aspartic proteases are bilobal enzymes each lobe contributing a catalytic Aspartate residue with an extended active site cleft localized between the two lobes of the molecule. The N- and C-terminal domains although structurally related by a 2-fold axis have only limited sequence homology except the vicinity of the active site. This suggests that the enzymes evolved by an ancient duplication event. Most members of the pepsin family specifically cleave bonds in peptides that are at least six residues in length with hydrophobic residues in both the P1 and P1' positions. The active site is located at the groove formed by the two lobes with an extended loop projecting over the cleft to form an 11-residue flap which encloses substrates and inhibitors in the active site.

Nucellins are important regulators of nucellar cell's progressive degradation after ovule fertilization. This degradation is a characteristic of programmed cell death. Nucellins are plant aspartic proteases specifically expressed in nucellar cells during degradation. The enzyme is characterized by having two aspartic protease catalytic site motifs the Asp-Thr-Gly-Ser in the N-terminal and Asp-Ser-Gly-Ser in the C-terminal region and two other regions nearly identical to two regions of plant aspartic proteases. Aspartic proteases are bilobal enzymes each lobe contributing a catalytic Asp residue with an extended active site cleft localized between the two lobes of the molecule. One lobe may be evolved from the other through ancient gene-duplication event. Although the three-dimensional structures of the two lobes are very similar the amino acid sequences are more divergent except for the conserved catalytic site motif.

Xylanase inhibitor-I (TAXI-I) is a member of potent TAXI-type inhibitors of fungal and bacterial family 11 xylanases. Plants developed a diverse battery of defense mechanisms in response to continual challenges by a broad spectrum of pathogenic microorganisms. Their defense arsenal includes inhibitors of cell wall-degrading enzymes which hinder a possible invasion and colonization by antagonists. Xylanases of fungal and bacterial pathogens are the key enzymes in the degradation of xylan in the cell wall. Plants secrete proteins that inhibit these degradation glycosidases including xylanase. Surprisingly TAXI-I displays structural homology with the pepsin-like family of aspartic proteases but is proteolytically nonfunctional because one or more residues of the essential catalytic triad are absent. The structure of the TAXI-inhibitor Aspergillus niger xylanase I complex illustrates the ability of tight binding and inhibition with subnanomolar affinity and indicates the importance of the C-terminal end for the differences in xylanase specificity among different TAXI-type inhibitors. This family also contains pepsin-like aspartic proteinases homologous to TAXI-I. Unlike TAXI-I they have active site aspartates and are functionally active. This family of aspartate proteases is classified by MEROPS as the peptidase family A1 (pepsin A clan AA).
rpsblast_cdd gnl|CDD|133160 87 442 + 356 Gaps:111 97.24 326 26.81 4e-10 cd06096 Plasmepsin_5 Plasmepsins are a class of aspartic proteinases produced by the plasmodium parasite. The family contains a group of aspartic proteinases homologous to plasmepsin 5. Plasmepsins are a class of at least 10 enzymes produced by the plasmodium parasite. Through their haemoglobin-degrading activity they are an important cause of symptoms in malaria sufferers. This family of enzymes is a potential target for anti-malarial drugs. Plasmepsins are aspartic acid proteases which means their active site contains two aspartic acid residues. These two aspartic acid residue act respectively as proton donor and proton acceptor catalyzing the hydrolysis of peptide bond in proteins. Aspartic proteinases are composed of two structurally similar beta barrel lobes each lobe contributing an aspartic acid residue to form a catalytic dyad that acts to cleave the substrate peptide bond. The catalytic Asp residues are contained in an Asp-Thr-Gly-Ser/thr motif in both N- and C-terminal lobes of the enzyme. There are four types of plasmepsins closely related but varying in the specificity of cleavage site. The name plasmepsin may come from plasmodium (the organism) and pepsin (a common aspartic acid protease with similar molecular structure). This family of aspartate proteases is classified by MEROPS as the peptidase family A1 (pepsin A clan AA).
rpsblast_cdd gnl|CDD|133137 87 214 + 128 Gaps:37 96.33 109 32.38 4e-08 cd05470 pepsin_retropepsin_like Cellular and retroviral pepsin-like aspartate proteases. This family includes both cellular and retroviral pepsin-like aspartate proteases. The cellular pepsin and pepsin-like enzymes are twice as long as their retroviral counterparts. The cellular pepsin-like aspartic proteases are found in mammals plants fungi and bacteria. These well known and extensively characterized enzymes include pepsins chymosin rennin cathepsins and fungal aspartic proteases. Several have long been known to be medically (rennin cathepsin D and E pepsin) or commercially (chymosin) important. The eukaryotic pepsin-like proteases contain two domains possessing similar topological features. The N- and C-terminal domains although structurally related by a 2-fold axis have only limited sequence homology except in the vicinity of the active site. This suggests that the enzymes evolved by an ancient duplication event. The eukaryotic pepsin-like proteases have two active site ASP residues with each N- and C-terminal lobe contributing one residue. While the fungal and mammalian pepsins are bilobal proteins retropepsins function as dimers and the monomer resembles structure of the N- or C-terminal domains of eukaryotic enzyme. The active site motif (Asp-Thr/Ser-Gly-Ser) is conserved between the retroviral and eukaryotic proteases and between the N-and C-terminal of eukaryotic pepsin-like proteases. The retropepsin-like family includes pepsin-like aspartate proteases from retroviruses retrotransposons and retroelements as well as eukaryotic DNA-damage-inducible proteins (DDIs) and bacterial aspartate peptidases. Retropepsin is synthesized as part of the POL polyprotein that contains an aspartyl-protease a reverse transcriptase RNase H and an integrase. The POL polyprotein undergoes specific enzymatic cleavage to yield the mature proteins. This family of aspartate proteases is classified by MEROPS as the peptidase family A1 (pepsin A) and A2 (retropepsin family).
