ID 2.3.1.250 DE [Wnt protein] O-palmitoleoyl transferase. AN porcupine. CA (9Z)-hexadecenoyl-CoA + [Wnt protein]-L-serine = [Wnt protein]-O-(9Z)- CA hexadecenoyl-L-serine + CoA. CC -!- The enzyme, found in animals, modifies a specific serine residue in CC Wnt proteins, e.g. Ser(209) in human Wnt3a and Ser(224) in chicken CC WNT1. CC -!- The enzyme can accept C13 to C16 fatty acids in vitro, but only (9Z)- CC hexadecenoate modification is observed in vivo. cf. EC 3.1.1.98.
