| Accepted name: |
[Wnt protein] O-palmitoleoyl transferase |
| Reaction: |
(9Z)-hexadec-9-enoyl-CoA + [Wnt]-L-serine = CoA + [Wnt]-O-(9Z)-hexadec-9-enoyl-L-serine |
| Glossary: |
(9Z)-hexadec-9-enoate = palmitoleoate |
| Other name(s): |
porcupine; PORCN (gene name) |
| Systematic name: |
(9Z)-hexadec-9-enoyl-CoA:[Wnt]-L-serine O-hexadecenoyltransferase |
| Comments: |
The enzyme, found in animals, modifies a specific serine residue in Wnt proteins, e.g. Ser209 in human Wnt3a and Ser224 in chicken WNT1 [2,3]. The enzyme can accept C13 to C16 fatty acids in vitro, but only (9Z)-hexadecenoate modification is observed in vivo [1]. cf. EC 3.1.1.98, [Wnt protein]-O-palmitoleoyl-L-serine hydrolase. |
