Ligands: C1K Related: 3zj6, 3zj8 Activity: 3-alpha-(S)-strictosidine beta-glucosidase, with EC number 3.2.1.105 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function [SG1_RAUSE] Glucosidase specifically involved in alkaloid biosynthesis leading to the accumulation of several alkaloids, including ajmaline, an important plant-derived pharmaceutical used in the therapy of heart disorders. Publication Abstract from PubMed Abstract Insight into the structure and inhibition mechanism of O-beta-d-glucosidases by deoxa-pyranosylamine type inhibitors is provided by X-ray analysis of complexes between raucaffricine and strictosidine glucosidases and N-(cyclohexylmethyl)-, N-(cyclohexyl)- and N-(bromobenzyl)-beta-d-gluco-1,5-deoxa-pyranosylamine. All inhibitors anchored exclusively in the catalytic active site by competition with appropriate enzyme substrates. Thus facilitated prospective elucidation of the binding networks with residues located at <3.9 A distance will enable the development of potent inhibitors suitable for the production of valuable alkaloid glucosides, raucaffricine and strictosidine, by means of synthesis in Rauvolfia serpentina cell suspension cultures. Ligand structures of synthetic deoxa-pyranosylamines with raucaffricine and strictosidine glucosidases provide structural insights into their binding and inhibitory behaviours.,Xia L, Lin H, Staniek A, Panjikar S, Ruppert M, Hilgers P, Williardt J, Rajendran C, Wang M, Warzecha H, Jager V, Stockigt J J Enzyme Inhib Med Chem. 2014 Aug 20:1-7.
