Asparagine is an amino acid used in protein synthesis, specifically the biosynthesis of glycoproteins. In E.coli, L-asparagine can be synthesized from L-aspartic acid by either utilizing asparagine synthetase B with L-glutamine or ammonia. Both reactions are driven by ATP however the reaction with ammonia utilizes both asparagine synthetase B and aspartate-ammonia ligase.
