ID 1.14.19.40 DE hex-5-enoyl-[acyl-carrier protein] acetylenase. CA 5-hexenoyl-[ACP] + 2 H(+) + O2 + 2 reduced [2Fe-2S]-[ferredoxin] = CA 5-hexynoyl-[ACP] + 2 H2O + 2 oxidized [2Fe-2S]-[ferredoxin]. CC -!- The enzyme, characterized from the marine cyanobacterium Moorea CC producens, is involved in production of the ion channel blocker CC jamaicamide A. CC -!- It is specific for hexanoate or hex-5-enoate loaded onto a dedicated CC acyl-carrier protein (JamC), which is encoded by a gene in the same CC operon. DR Q6E7K8, JAMB_MOOP1 ; //
