In enzymology a tyrosine-arginine ligase (EC 6.3.2.24) is an enzyme that catalyzes the chemical reactionATP + L-tyrosine + L-arginine AMP + diphosphate + L-tyrosyl-L-arginineThe 3 substrates of this enzyme are ATP L-tyrosine and L-arginine whereas its 3 products are AMP diphosphate and L-tyrosyl-L-arginine.This enzyme belongs to the family of ligases specifically those forming carbon-nitrogen bonds as acid-D-amino-acid ligases (peptide synthases).
