EC 6.3.2.46     
Accepted name: fumarate—(S)-2,3-diaminopropanoate ligase
Reaction: ATP + fumarate + L-2,3-diaminopropanoate = AMP + diphosphate + N3-fumaroyl-L-2,3-diaminopropanoate
Glossary: N3-fumaroyl-L-2,3-diaminopropanoate = (2E)-4-{[(2S)-2-amino-2-carboxyethyl]amino}-4-oxobut-2-enoate
L-2,3-diaminopropanoate = (S)-2,3-diaminopropanoate
Other name(s): DdaG; fumarate:(S)-2,3-diaminopropanoate ligase (AMP-forming)
Systematic name: fumarate:L-2,3-diaminopropanoate ligase (AMP-forming)
Comments: 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.
