Crystal structure of TcOYE with pHBACrystal structure of TcOYE with pHBA
Structural highlights
Publication Abstract from PubMedOld yellow enzyme (OYE) is an NADPH oxidoreductase capable of reducing a variety of compounds. It contains flavin mononucleotide (FMN) as a prosthetic group. A ternary complex structure of OYE from Trypanosoma cruzi (TcOYE) with FMN and one of the substrates, p-hydroxybenzaldehyde, shows a striking movement around the active site upon binding of the substrate. From a structural comparison of other OYE complexed with 12-oxophytodienoate, we have constructed a complex structure with another substrate, prostaglandin H(2) (PGH(2)), to provide a proposed stereoselective reaction mechanism for the reduction of PGH(2) to prostaglandin F(2alpha) by TcOYE. Structural insight into the stereoselective production of PGF2alpha by Old Yellow Enzyme from Trypanosoma cruzi.,Okamoto N, Yamaguchi K, Mizohata E, Tokuoka K, Uchiyama N, Sugiyama S, Matsumura H, Inaka K, Urade Y, Inoue T J Biochem. 2011 Nov;150(5):563-8. doi: 10.1093/jb/mvr096.
