CC   -!- This enzyme catalyzes the ultimate reaction in the yeast sphingolipid
CC       biosynthesis pathway.
CC   -!- It transfers a second phosphoinositol group to mannosyl-inositol-
CC       phospho-alpha-hydroxyphytoceramide (MIPC), forming the final and most
CC       abundant yeast sphingolipid, mannosyl-diphosphoinositol-ceramide
CC       (MIP2C).
