Hydrolysis with a beta-lactamase results in the formation of compounds with lambda(ma. 230nm from ns and cephalosporins, but not from ins. 3. These different compounds decompose to give penaldates and penamaldates derived from the side chain and the carbon atoms of the beta-lactam ring. 4. Derivatives similar to those obtained with simple amino compounds appear to be formed when cephalosporins and their analogues react with lysine polymers

many different penicillins and cephalosporin-like products in vitro

The purification to homogeneity of some of these proteins as well as their biochemical characterization has allowed some of them to be used for synthesizing many different penicillins and cephalosporin-like products in vitro. The use of purified acyl-CoA: 6-aminopenicillanic acid (6-APA) acyltransferase (AT) from Penicillium chrysogenum and several acyl-CoA ligases obtained from different microbial origins has led to the reproduction "in vitro" of the last step involved in in penicillin biosynthesis. By coupling these enzymatic systems (AT and acyl-CoA ligases) an impressive number of beta-lactam antibiotics has been obtained.
