Gene NameERG11
Enzyme Class
Biological Properties
General FunctionInvolved in iron ion binding
Specific FunctionCatalyzes 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
Cellular LocationMembrane; Single-pass membrane protein
