Accepted name: bisucaberin synthase
Reaction: 2 ATP + 2 N1-hydroxy-N1-succinylcadaverine = 2 AMP + 2 diphosphate + bisucaberin (overall reaction)
(1a) ATP + 2 N1-hydroxy-N1-succinylcadaverine = AMP + diphosphate + bisucaberin B
(1b) ATP + bisucaberin B = AMP + diphosphate + bisucaberin
Glossary: bisucaberin B = pre-bisucaberin = 3-[(5-{3-[(5-aminopentyl)(hydroxy)carbamoyl]propanamido}pentyl)(hydroxy)carbamoyl]propanoate
bisucaberin = 1,12-dihydroxy-1,6,12,17-tetrazacyclodocosane-2,5,13,16-tetrone
Other name(s): pubC (gene name); BibC C-terminal domain
Systematic name: N1-hydroxy-N1-succinylcadaverine:N1-hydroxy-N1-succinylcadaverine ligase
Comments: Requires Mg2+. The enzyme, characterized from the bacterium Aliivibrio salmonicida, catalyses the last step in the biosynthesis of the siderophore bisucaberin. The enzyme catalyses the reaction in two steps - concatenation of two molecules of N1-hydroxy-N1-succinylcadaverine, followed by cyclization.
