===carboxymethylproline synthase (CarB) from pectobacterium carotovora, apo enzyme===

[https://www.uniprot.org/uniprot/CARB_PECCC CARB_PECCC] Catalyzes the formation of (2S,5S)-carboxymethylproline (t-CMP) from malonyl-CoA and (S)-1-pyrroline-5-carboxylate, the first step in the biosynthesis of (5R)-carbapen-2-em-3-carboxylate, a beta-lactam antibiotic of the carbapenem class (PubMed:15595850, PubMed:14625287). Also catalyzes the independent decarboxylation of malonyl-CoA and methylmalonyl-CoA and the hydrolysis of CoA esters such as acetyl-CoA and propionyl-CoA (PubMed:15595850). Catalyzes the reaction with a C2 epimeric mixture of methylmalonyl-CoA to give a 55:45 mixture of (6R)- and (6S)-epimers of 6-methyl-t-CMP, under standard incubation conditions (PubMed:21505494).<ref>PMID:14625287</ref> <ref>PMID:15595850</ref> <ref>PMID:15726176</ref> <ref>PMID:18972478</ref> <ref>PMID:21505494</ref>
