The ____ enzymes join the sugar-linked peptides to x-link polysaccharide chains
Transpeptidase
Normally, bacterial cell walls grow with the D-Ala D-ala being link by a _____ attached to an anyme, which then allows Glycine to come in with a substitution reaction
Serine
B-lactam antibiotics cause the amino acid ____ to irreversibly bind onto the b-lactam ring
Serine
Clavulanic acid and Tazobactam, and Avibactam are all _____ inhibitors, which is great for pharmacists to fight back!
