ID 2.4.1.370 DE inositol phosphorylceramide mannosyltransferase. CA a 1D-myo-inositol-1-phospho-N-[(R)-2-hydroxy-very-long-chain fatty acyl]- CA (R)-4-hydroxysphingoid base + GDP-alpha-D-mannose = an alpha-D-mannosyl- CA (1<->6)-1D-myo-inositol-1-phospho-N-[(R)-2-hydroxy-very-long-chain fatty CA acyl]-(R)-4-hydroxysphingoid base + GDP + H(+). CC -!- The simplest complex sphingolipid of yeast, inositol-phospho-alpha- CC hydroxyphytoceramide (IPC), is usually mannosylated to yield CC mannosyl-inositol-phospho-alpha hydroxyphytoceramide (MIPC). CC -!- The enzyme is located in the Golgi apparatus, and utilizes GDP-alpha- CC D-mannose as the mannosyl group donor. CC -!- It consists of a catalytic subunit (SUR1 or CSH1) and a regulatory CC subunit (CSG2). DR P38287, CSH1_YEAST ; P33300, SUR1_YEAST ; //
