Biosynthesis, i.e., chemical synthesis occurring in biological contexts, is a term most often referring to multi-step, enzyme-catalyzed processes where chemical substances absorbed as nutrients (or previously converted through biosynthesis) serve as enzyme substrates, with conversion by the living organism either into simpler or more complex ...
Cefepime is a fourth-generation cephalosporin antibiotic.Cefepime has an extended spectrum of activity against Gram-positive and Gram-negative bacteria, with greater activity against both types of organism than third-generation agents.

This is essential for the cephamycin C and clavulanic acid, but not the 5S claims. CcaR is important for the expression of polycistronic transcripts, which are early genes for clavulanic acid biosynthesis. This is also a key factor for activating its own transcription by binding to its own promoting region. [12]
