IntEnz Enzyme Nomenclature


Accepted name:
UDP-N-acetylmuramoyl-L-alanine—L-glutamate ligase
Other names:
UDP-N-acetyl-α-D-muramoyl-L-alanyl-L-glutamate synthetase
UDP-MurNAc-L-Ala-L-Glu synthetase
Systematic name:
UDP-N-acetylmuramoyl-L-alanine—L-glutamate ligase (ADP-forming)



The enzyme, characterized from the bacterium Xanthomonas oryzae, catalyses the ligation of a terminal L-glutamate to UDP-N-acetyl-α-D-muramoyl-L-alanine. The combined activity of this enzyme and EC, UDP-N-acetyl-α-D-muramoyl-L-alanyl-L-glutamate epimerase, provides an alternative route for incorporating D-glutamate into peptidoglycan, replacing the more common combination of EC, glutamate racemase, and EC, UDP-N-acetylmuramoyl-L-alanine—D-glutamate ligase.
