Crystal Structure of Perakine Reductase, Founder Member of a Novel AKR Subfamily with Unique Conformational Changes during NADPH Binding
Template:ABSTRACT PUBMED 22334702
Function
[PERR_RAUSE] Aldo-keto reductase involved in the biosynthesis of monoterpenoid indole alkaloids. Broad substrate specificity enzyme with a high selectivity in the group of alkaloids. Can use perakine, 19(S),20(R)-dihydro-peraksine-17,21-al, cinnamic aldehyde, p-coumaric aldehyde and 3-(3,4,5-trimethoxyphenyl)propanal as substrates, but not ketosteroids such as progesterone. NADPH could not be replaced by NADH.[1]
About this Structure
3v0t is a 1 chain structure with sequence from Rauvolfia serpentina. Full crystallographic information is available from OCA.
