DE   mannosyl-inositol-phosphoceramide inositolphosphotransferase.
CA   a 1,2-diacyl-sn-glycero-3-phospho-(1D-myo-inositol) + an alpha-D-
CA   mannosyl-(1<->6)-1D-myo-inositol-1-phospho-N-[(R)-2-hydroxy-very-long-
CA   chain fatty acyl]-(R)-4-hydroxysphingoid base = a 1,2-diacyl-sn-glycerol
CA   + an alpha-D-mannosyl-6-(1D-myo-inositol phospho)-(1<->6)-1D-myo-
CA   inositol-1-phospho-N-[(R)-2-hydroxy-very-long-chain fatty acyl]-(R)-4-
CA   hydroxysphingoid base.
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).
