Cycloserine inhibits

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 … Cycloserine works as an antibiotic by inhibiting cell-wall biosynthesis in bacteria. As a cyclic analogue of D-alanine, cycloserine acts against two crucial enzymes important in the cytosolic stages of peptidoglycan synthesis: alanine racemase (Alr) and D-alanine:D-alanine ligase (Ddl).
