Genetic analyses involving interactions between the ergosterol biosynthetic enzymes, lanosterol synthase (Erg7p) and 3-ketoreductase (Erg27p), in the yeast Saccharomyces cerevisiae.

Abstract excerpt

Protein-protein interaction studies in the Saccharomyces cerevisiae ergosterol biosynthetic pathway suggest that enzymes in this pathway may act as an integrated multienzyme complex. The yeast sterol 3-ketoreductase (Erg27p) required for C-4 demethylation of sterols has previously been shown to also be required for the function of the upstream oxidosqualene cyclase/lanosterol synthase (Erg7p); thus, erg27 mutants...
