Entry
EC 4.3.1.14                 Enzyme                                 
Name
3-aminobutyryl-CoA ammonia-lyase;
L-3-aminobutyryl-CoA deaminase;
L-3-aminobutyryl-CoA ammonia-lyase
Class
Lyases;
Carbon-nitrogen lyases;
Ammonia-lyases
BRITE hierarchy
Sysname
L-3-aminobutyryl-CoA ammonia-lyase (crotonoyl-CoA-forming)
Reaction(IUBMB)
L-3-aminobutyryl-CoA = crotonoyl-CoA + NH3 [RN:R03030]
Reaction(KEGG)
Substrate
L-3-aminobutyryl-CoA [CPD:C05231]
Product
crotonoyl-CoA [CPD:C00877];
NH3 [CPD:C00014]
Comment
Hydroxylamine can replace ammonia as a substrate. Crotonoyl-pantetheine can replace crotonoyl-CoA but it is a poorer substrate.
