Enzymatic reaction of: phosphatidylcholine:diacylglycerol cholinephosphotransferase

EC Number: 2.7.8.-

a phosphatidylcholine + a 1,2-diacyl-sn-glycerol <=> a 1,2-diacyl-sn-glycerol + a phosphatidylcholine

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction in which it was curated.

Reversibility of this reaction is unspecified.

In Pathways: diacylglycerol biosynthesis (PUFA enrichment in oilseed)

Summary:
A novel enzyme was recently isolated from Arabidopsis [Lu09b]. The Arabidopsis phosphatidylcholine:diacylglycerol cholinephosphotransferase, encoded by ROD1, catalyzed the transfer of phosphocholine head group from PC to DAG. Yeast microsomes expressing ROD1 had an enzyme activity of 0.6 nmol/mg/min in the absence of added PC, whereas the enzyme activity increased to 4.5 nmol/mg/min when 1 mM PC was added.

pH(opt): 6.5-7 [Lu09b]
