EC number
2.8.3.21
Accepted name
L-carnitine CoA-transferase
Reaction
(1) (E)-4-(trimethylammonio)but-2-enoyl-CoA + L-carnitine = (E)-4-(trimethylammonio)but-2-enoate + L-carnitinyl-CoA;;(2) 4-trimethylammoniobutanoyl-CoA + L-carnitine = 4-trimethylammoniobutanoate + L-carnitinyl-CoA
Other name(s)
CaiB, crotonobetainyl/γ-butyrobetainyl-CoA:carnitine CoA-transferase
Systematic name
(E)-4-(trimethylammonio)but-2-enoyl-CoA:L-carnitine CoA-transferase
Comment
The enzyme is found in gammaproteobacteria such as Proteus sp. and Escherichia coli. It has similar activity with both substrates.
