Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at transcript leveli

Functioni

Catalyzes C14-demethylation of lanosterol; it transforms lanosterol into 4,4'-dimethyl cholesta-8,14,24-triene-3-beta-ol.By similarity

Catalytic activityi

A 14-alpha-methylsteroid + 3 O2 + 3 NADPH = a Delta(14)-steroid + formate + 3 NADP+ + 4 H2O.

Cofactori

hemeBy similarity

Pathwayi: zymosterol biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes zymosterol from lanosterol.
Proteins known to be involved in the 6 steps of the subpathway in this organism are:
  1. Lanosterol 14-alpha demethylase (CYP51A1)
  2. no protein annotated in this organism
  3. Methylsterol monooxygenase 1 (MSMO1)
  4. no protein annotated in this organism
  5. no protein annotated in this organism
  6. no protein annotated in this organism
This subpathway is part of the pathway zymosterol biosynthesis, which is itself part of Steroid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes zymosterol from lanosterol, the pathway zymosterol biosynthesis and in Steroid biosynthesis.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
