Entry
EC 1.14.20.3                Enzyme                                 

Name
(5R)-carbapenem-3-carboxylate synthase;
carC (gene name)
Class
Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With 2-oxoglutarate as one donor, and the other dehydrogenated
Sysname
(3S,5S)-carbapenam-3-carboxylate,2-oxoglutarate:oxygen oxidoreductase (dehydrating)
Reaction(IUBMB)
(3S,5S)-carbapenam-3-carboxylate + 2-oxoglutarate + O2 = (5R)-carbapen-2-em-3-carboxylate + succinate + CO2 + H2O [RN:R10415]
Reaction(KEGG)
R10415
Substrate
(3S,5S)-carbapenam-3-carboxylate [CPD:C17367];
2-oxoglutarate [CPD:C00026];
O2 [CPD:C00007]
Product
(5R)-carbapen-2-em-3-carboxylate [CPD:C06669];
succinate [CPD:C00042];
CO2 [CPD:C00011];
H2O [CPD:C00001]
Comment
Requires Fe2+. The enzyme is involved in the biosynthesis of the carbapenem beta-lactam antibiotic (5R)-carbapen-2-em-3-carboxylate in the bacterium Pectobacterium carotovorum. It catalyses a stereoinversion at C-5 and introduces a double bond between C-2 and C-3.
