cephamycin Cephamycins are a group of β-lactam antibiotics. They are very similar to cephalosporins, and the cephamycins are sometimes classified as cephalosporins. Like cephalosporins, cephamycins are based upon the cephem nucleus. Unlike most cephalospor ...

penicillin Penicillins (P, PCN or PEN) are a group of β-lactam antibiotics originally obtained from ''Penicillium'' moulds, principally '' P. chrysogenum'' and '' P. rubens''. Most penicillins in clinical use are synthesised by P. chrysogenum using ...

and the antibacterial 4-fluoro-L-threonine. The γ-Glu-βes pathway to biosynthesis of non-traditional amino acids β-ethynylserine (βes) and L-propargylglycine (Pra) was first characterized in this species. The genome, which was sequenced in 2011, contains one chromosome with 6,283,062 base pairs and one megaplasmid with 1,809,491 bp, with an overall guanine-cytosine content of 73%.
