Name: UDP-N-Acetylmuramoyl-L-alanine
Description:Udp-n-acetylmuramoyl-l-alanine belongs to the class of Pyrimidine Nucleotide Sugars. These are pyrimidine nucleotides bound to a saccharide derivative through the terminal phosphate group. (inferred from compound structure)UDP-N-acetylmuramoyl-L-alanine (UDP-MurNAc-L-Ala), which is the nucleotide substrate of the D-glutamic-acid-adding enzyme (the murD gene product) catalyzing the subsequent step in the pathway for peptidoglycan synthesis, appears to be an effector of the racemase activity. (PMID 8098327) MurD (UDP-N-acetylmuramoyl-L-alanine:D-glutamate ligase) is the second enzyme in the series of Mur ligases, and it catalyzes the addition of D-glutamic acid (D-Glu) to the cytoplasmic intermediate UDP-N-acetylmuramoyl-L-alanine (UMA).
