Contents

Sterol 14 alpha-demethylase (CYP51) from Trypanosoma cruzi in complex with the pyridine inhibitor (S)-2-(4-chlorophenyl)-2-(pyridin-3-yl)-1- (4-(4-(trifluoromethyl)phenyl)piperazin-1-yl)ethanone (EPL-BS1246,UDO)

Template:ABSTRACT PUBMED 24047900

Function

[CP51_TRYCC] Catalyzes C14-demethylation of lanosterol which is critical for ergosterol biosynthesis. It transforms lanosterol into 4,4'-dimethyl cholesta-8,14,24-triene-3-beta-ol (By similarity). Favors C4 dimethylated substrates, the substrate preference order is 24-methylenedihydrolanosterol > 24,25-dihydrolanosterol > lanosterol > obtusifoliol > norlanosterol.[1] [UniProtKB:P0A512]
