Aerobactin synthase

This enzyme belongs to the family of ligases, specifically those forming carbon-nitrogen bonds as acid-D-amino-acid ligases (peptide synthases). The systematic name of this enzyme class is citrate:N⁶-acetyl-N⁶-hydroxy-L-lysine ligase (ADP-forming). This enzyme is also called citrate:6-N-acetyl-6-N-hydroxy-L-lysine ligase (ADP-forming). This enzyme participates in lysine degradation.
