Sysname
fumarate:L-2,3-diaminopropanoate ligase (AMP-forming)
Reaction(IUBMB)
ATP + fumarate + L-2,3-diaminopropanoate = AMP + diphosphate + N3-fumaroyl-L-2,3-diaminopropanoate [RN:R10940]
Reaction(KEGG)
R10940
Substrate
ATP [CPD:C00002];
fumarate [CPD:C00122];
L-2,3-diaminopropanoate [CPD:C03401]
Product
AMP [CPD:C00020];
diphosphate [CPD:C00013];
N3-fumaroyl-L-2,3-diaminopropanoate [CPD:C20961]
Comment
The enzyme, characterized from the bacterium Enterobacter agglomerans, is involved in biosynthesis of dapdiamide tripeptide antibiotics, a family of fumaramoyl- and epoxysuccinamoyl-peptides named for the presence of an L-2,3-diaminopropanoate (DAP) moiety and two amide linkages in their scaffold.
