: zymosterol biosynthesis Pathwayi
This protein is involved in step 3 of the subpathway that synthesizes zymosterol from lanosterol. 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.
