malonyl-CoA + (S)-1-pyrroline-5-carboxylate + H2O | CarB is a member of the crotonase superfamily of enzymes. In addition to decarboxylation and thioester hydrolysis steps, it catalyzes C-C bond formation leading to a substituted heterocycle. Mechanistic studies show that C-C bond formation by CarB most probably occurs by reaction of P5C with an oxy-anion stabilized enolate, and thioester hydrolysis most probably proceeds by direct attack of an activated water molecule | Pectobacterium carotovorum | CoA + (2S,5S)-5-carboxymethylproline + CO2 | - |
