| Hit Description | cd07816 Bet_v1-like Ligand-binding bet_v_1 domain of major pollen allergen of white birch (Betula verrucosa) Bet v 1 and related proteins. This family includes the ligand binding domain of Bet v 1 (the major pollen allergen of white birch Betula verrucosa) and related proteins. In addition to birch Bet v 1 this family includes other plant intracellular pathogenesis-related class 10 (PR-10) proteins norcoclaurine synthases (NCSs) cytokinin binding proteins (CSBPs) major latex proteins (MLPs) and ripening-related proteins. It belongs to the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. Members of this family binds a diverse range of ligands. Bet v 1 can bind brassinosteroids cytokinins flavonoids and fatty acids. Hyp-1 a PR-10 from Hypericum perforatum/St. John's wort catalyzes the condensation of two molecules of emodin to the bioactive naphthodianthrone hypericin. NCSs catalyze the condensation of dopamine and 4-hydroxyphenylacetaldehyde to (S)-norcoclaurine the first committed step in the biosynthesis of benzylisoquinoline alkaloids such as morphine. The role of MLPs is unclear however they are associated with fruit and flower development and in pathogen defense responses. A number of PR-10 proteins in this subgroup including Bet v 1 have in vitro RNase activity the biological significance of which is unclear. Bet v 1 family proteins have a conserved glycine-rich P (phosphate-binding)-loop proximal to the entrance of the ligand-binding pocket. However its conformation differs from that of the canonical P-loop structure found in nucleotide-binding proteins. Several PR-10 members including Bet v1 are allergenic. Cross-reactivity of Bet v 1 with homologs from plant foods results in birch-fruit syndrome. | Hit Pcons | 17.07 |
