KEGG   ENZYME: 1.3.8.13Help
Entry
EC 1.3.8.13                 Enzyme                                 

Name
crotonobetainyl-CoA reductase;
caiA (gene name)
Class
Oxidoreductases;
Acting on the CH-CH group of donors;
With a flavin as acceptor
BRITE hierarchy
Sysname
gamma-butyrobetainyl-CoA:electron-transfer flavoprotein 2,3-oxidoreductase
Reaction(IUBMB)
gamma-butyrobetainyl-CoA + electron-transfer flavoprotein = crotonobetainyl-CoA + reduced electron-transfer flavoprotein [RN:R11600]
Reaction(KEGG)
Substrate
gamma-butyrobetainyl-CoA [CPD:C20749];
electron-transfer flavoprotein [CPD:C04253]
Product
crotonobetainyl-CoA [CPD:C20748];
reduced electron-transfer flavoprotein [CPD:C04570]
Comment
The enzyme has been purified from the bacterium Escherichia coli O44 K74, in which it forms a complex with EC 2.8.3.21, L-carnitine CoA-transferase. The electron donor is believed to be an electron-transfer flavoprotein (ETF) encoded by the fixA and fixB genes.
