Function
function
Catalyzes both phosphatidylcholine and phosphatidylethanolamine biosynthesis from CDP-choline and CDP-ethanolamine, respectively. Involved in protein-dependent process of phospholipid transport to distribute phosphatidyl choline to the lumenal surface. Has a higher cholinephosphotransferase activity than ethanolaminephosphotransferase activity.
Catalytic activity
- 1,2-di-(9Z-hexadecenoyl)-sn-glycerol + CDP-choline = 1,2-di-(9Z-hexadecenoyl)-sn-glycero-3-phosphocholine + CMP + H+This reaction proceeds in the forward direction.
- 1,2-di-(9Z-hexadecenoyl)-sn-glycerol + CDP-ethanolamine = 1,2-di-(9Z-hexadecenoyl)-sn-glycero-3-phosphoethanolamine + CMP + H+This reaction proceeds in the forward direction.
- CDP-choline + 1,2-di-(9Z-octadecenoyl)-sn-glycerol = 1,2-di-(9Z-octadecenoyl)-sn-glycero-3-phosphocholine + CMP + H+This reaction proceeds in the forward direction.
- CDP-ethanolamine + 1,2-di-(9Z-octadecenoyl)-sn-glycerol = 1,2-di-(9Z-octadecenoyl)-sn-glycero-3-phosphoethanolamine + CMP + H+This reaction proceeds in the forward direction.
- 1,2-didecanoyl-sn-glycerol + CDP-choline = 1,2-didecanoyl-sn-glycero-3-phosphocholine + CMP + H+This reaction proceeds in the forward direction.
- 1,2-dioctanoyl-sn-glycerol + CDP-choline = 1,2-dioctanoyl-sn-glycero-3-phosphocholine + CMP + H+This reaction proceeds in the forward direction.
- 1-O-hexadecyl-2-(5Z,8Z,11Z,14Z-eicosatetraenoyl)-sn-glycerol + CDP-choline = 1-O-hexadecyl-2-(5Z,8Z,11Z,14Z)-eicosatetraenoyl-sn-glycero-3-phosphocholine + CMP + H+This reaction proceeds in the forward direction.
- 1-O-hexadecyl-2-acetyl-sn-glycerol + CDP-choline = 1-O-hexadecyl-2-acetyl-sn-glycero-3-phosphocholine + CMP + H+This reaction proceeds in the forward direction.
- 1-hexadecanoyl-2-(4Z,7Z,10Z,13Z,16Z,19Z-docosahexaenoyl)-sn-glycerol + CDP-choline = 1-hexadecanoyl-2-(4Z,7Z,10Z,13Z,16Z,19Z-docosahexaenoyl)-sn-glycero-3-phosphocholine + CMP + H+This reaction proceeds in the forward direction.
- 1-hexadecanoyl-2-(9Z-octadecenoyl)-sn-glycerol + CDP-choline = 1-hexadecanoyl-2-(9Z-octadecenoyl)-sn-glycero-3-phosphocholine + CMP + H+This reaction proceeds in the forward direction.
