show Brenda entry

EC number

1.3.8.13

Accepted name

crotonobetainyl-CoA reductase

Reaction

γ-butyrobetainyl-CoA + electron-transfer flavoprotein = crotonobetainyl-CoA + reduced electron-transfer flavoprotein

Other name(s)

caiA (gene name)

Systematic name

γ-butyrobetainyl-CoA:electron-transfer flavoprotein 2,3-oxidoreductase

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.
