Synthesis of 3-furylmethylpenicillin using an enzymatic procedure

Abstract

3-Furylmethylpenicillin was synthesized in vitro from 3-furylacetic acid, 6-aminopenicillanic acid (6-APA), CoA, ATP and Mg2+. The reaction was catalyzed in two steps by the enzymes phenylacetyl-CoA ligase (PCL) from Pseudomonas putida and acyl-CoA: 6-APA acyltransferase (AT) from Penicillium chrysogenum. PCL catalyzes the activation of 3-furylacetic acid to 3-furylacetyl-CoA (3-F-CoA) and AT acylates the amino group of 6-APA with the 3-furylacetyl moiety of 3-F-CoA, releasing CoA and 3-furylmethylpenicillin. © 1991.
