6.3.2.47
Accepted name
dapdiamide synthase
Reaction
(1) ATP + 3-{[(2E)-4-amino-4-oxobut-2-enoyl]amino}-L-alanine + L-valine = ADP + phosphate + 3-{[(2E)-4-amino-4-oxobut-2-enoyl]amino}-L-alanyl-L-valine;;(2) ATP + 3-{[(2E)-4-amino-4-oxobut-2-enoyl]amino}-L-alanine + L-isoleucine = ADP + phosphate + 3-{[(2E)-4-amino-4-oxobut-2-enoyl]amino}-L-alanyl-L-isoleucine;;(3) ATP + 3-{[(2E)-4-amino-4-oxobut-2-enoyl]amino}-L-alanine + L-leucine = ADP + phosphate + 3-{[(2E)-4-amino-4-oxobut-2-enoyl]amino}-L-alanyl-L-leucine;;(4) ATP + 3-({[(2R,3R)-3-carbamoyloxiran-2-yl]carbonyl}amino)-L-alanine + L-valine = ADP + phosphate + 3-({[(2R,3R)-3-carbamoyloxiran-2-yl]carbonyl}amino)-L-alanyl-L-valine
Other name(s)
DdaF,
dapdiamide A synthase
Systematic name
3-{[(2E)-4-amino-4-oxobut-2-enoyl]amino}-L-alanine:L-valine ligase (ADP-forming)
Comment
The enzyme, characterized from the bacterium Pantoea agglomerans, is involved in biosynthesis of dapdiamide tripeptide antibiotics, a family of fumaramoyl- and epoxysuccinamoyl-peptides named for the presence of an (S)-2,3-diaminopropanoate (DAP) moiety and two amide linkages in their scaffold.
