Other Notes Broad spectrum third generation cephalosporin antibiotic. Biochem/physiol Actions Cefotaxim inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) which inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls. As a result, bacteria lyse due to cell wall autolytic enzymes. Cefotaxime, a cephalosporin antibiotic, is active against both gram-negative and gram-positive bacteria. In addition, cefotaxime blocks the division of cyanobacteria and lower plant organelles/plastids such as the photosynthetic organelles of Glaucophytes and chloroplasts of bryophytes.

As a result, bacteria lyse due to cell wall autolytic enzymes. Other Notes Broad spectrum third generation cephalosporin antibiotic. Application Cefotaxim is a broad spectrum third generation cephalosporin antibiotic that is used to study the effect of expression, binding and inhibition of penicillin-binding proteins especially PBP2 on bacterial cell wall mucopeptide synthesis. It has been used to find new residues involved in cefotaxime hydrolysis in CTX-M β-lactamases1, to study antibiotic-susceptible and -resistant Streptococcus pneumoniae infections 2, and to study pneumococcal pneumonia and the pharmokinetics of various treatments3.
