Abstract From the Canadian patent

X-6932, Abstract, The present invention comprises novel DNA compounds that encode isopenicillin N synthetase. The invention also comprises methods, transformants and, polypeptides related to the novel DNA compounds. The novel isopenicillin N synthetase-encoding DNA together, with its associated transcription and translation activating sequence, was isolated from Penicillium chrysogenum. The isopenicillin N synthetase-encoding DNA can be used to construct novel E. coli expression vectors that drive expression of isopenicillin N synthetase in E. coli. The intact P. chrysogenum isopenicillin N synthetase-encoding DNA and associated transcription and translation activating sequence can also be …
