Indoleacetate—lysine synthetase

The 3 substrates of this enzyme are ATP, (indol-3-yl)acetate, and L-lysine, whereas its 3 products are ADP, phosphate, and [[N6-[(indol-3-yl)acetyl]-L-lysine]].

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 (indol-3-yl)acetate:L-lysine ligase (ADP-forming). This enzyme is also called indoleacetate:L-lysine ligase (ADP-forming).
