1.14.14.46
Pimeloyl-[acyl-carrier protein] synthase.
based on mapping to UniProt P53554
A long-chain acyl-[acyl-carrier protein] + 2 reduced flavodoxin + 3 O(2) = pimeloyl-[acyl-carrier protein] + an n-alkanal + 2 oxidized flavodoxin + 3 H(2)O.
-!- Catalyzes an oxidative C-C bond cleavage of long-chain acyl-[acyl- carrier protein]s of various lengths to generate pimeloyl-[acyl- carrier protein], an intermediate in the biosynthesis of biotin. -!- The preferred substrate of the enzyme from the bacterium Bacillus subtilis is palmitoyl-[acyl-carrier protein] which then gives heptanal as the alkanal. -!- The mechanism is similar to EC 1.14.15.6, followed by a hydroxylation step, which may occur spontaneously. -!- Formerly EC 1.14.15.12.
