http://purl.uniprot.org/citations/2620834http://www.w3.org/2000/01/rdf-schema#comment"The N-2 strain of Acremonium chrysogenum accumulates the beta-lactam precursor tripeptide delta-(L-alpha-amino-adipoyl)-L-cysteinyl-D-valine and has no discernible activity for three of the cephalosporin C (Ce) biosynthetic enzymes. This phenotype is consistent with a mutation either within pcbC [the isopenicillin N synthetase (IPNS)-encoding gene] or in a pathway-regulator gene. To distinguish these possibilities we have cloned and sequenced pcbC from strain N-2. There is a single C----T mutation at nt 854 within the coding sequence, changing aa 285 from proline to leucine. An IPNS-specific monoclonal antibody recognises a catalytically inactive IPNS protein in extracts of N-2 cells. These findings suggest that strain N-2 carries a simple IPNS mutation and that IPNS or its biosynthetic product isopenicillin N is involved in regulation of the later stages of the Ce biosynthetic pathway."xsd:string
