WebCycloserine inhibits the early stages of murein synthesis where D-alanyl-D-alanine is added to the growing peptide side chain. The antibiotic resembles D-alanine in spatial structure, and it competitively inhibits the racemase reaction that converts L-alanine to D-alanine and the synthetase reaction that joins two D-alanine molecules. ... WebCycloserine It is a structural analog of D-alanine. As a result, it inhibits the incorporation of D-alanine into the peptidoglycan pentapeptide by inhibiting alanine racemase (which …
WebFor example, D-cycloserine inhibits two enzymes involved in the precursor synthesis, preventing both conversions of L-alanine to D-alanine by racemase, and the construction of D-alanyl-D-alanine by D-Ala-D-Ala ligase. In addition, transpeptidases and transglycosylases link newly formed peptidoglycan structures to the cell wall …
