N2 citryl N6 acetyl N6 hydroxylysine synthase

N²-citryl-N⁶-acetyl-N⁶-hydroxylysine synthase (EC 6.3.2.38, N(alpha)-citryl-N(epsilon)-acetyl-N(epsilon)-hydroxylysine synthase, iucA (gene)) is an enzyme with systematic name citrate:N⁶-acetyl-N⁶-hydroxy-L-lysine ligase (ADP-forming). This enzyme catalyses the following chemical reaction

2 ATP + citrate + N⁶-acetyl-N⁶-hydroxy-L-lysine + H₂O ⇌ 2 ADP + 2 phosphate + N²-citryl-N⁶-acetyl-N⁶-hydroxy-L-lysine

This enzyme requires Mg²⁺.
