Sysname
citrate:N6-acetyl-N6-hydroxy-L-lysine ligase (ADP-forming)
Reaction(IUBMB)

Reaction(KEGG)
Substrate
ATP [CPD:C00002];
citrate [CPD:C00158];
N6-acetyl-N6-hydroxy-L-lysine [CPD:C03955];
H2O [CPD:C00001]
Product
ADP [CPD:C00008];
phosphate [CPD:C00009];
N2-citryl-N6-acetyl-N6-hydroxy-L-lysine [CPD:C20333]
Comment
Requires Mg2+. Aerobactin is one of a group of high-affinity iron chelators known as siderophores and is produced under conditions of iron deprivation [5]. It is a dihydroxamate comprising two molecules of N6-acetyl-N6-hydroxy-L-lysine and one molecule of citrate. This enzyme catalyses the first of two synthase reactions to link N6-acetyl-N6-hydroxy-L-lysine and citrate [4,5].
