IntEnz Enzyme Nomenclature
EC 1.3.8.13

Names

Accepted name:
crotonobetainyl-CoA reductase
Other name:
caiA (gene name)
Systematic name:
γ-butyrobetainyl-CoA:electron-transfer flavoprotein 2,3-oxidoreductase

Reaction

Comments:

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.
