Latest Patents

John Henry Bull holds a patent for "DNA encoding ACV synthetase." This invention involves the DNA encoding the gene for the synthetase enzyme capable of generating δ (L-a-aminoadipyl)-L-cysteinyl-D-valine (ACV) from its constituent amino acids. The DNA was obtained from several penicillin and cephalosporin-producing organisms, such as cephalosporium and a Flavobacterium species. The patent describes the preparation of recombinant vectors comprising the ACV synthetase gene and hosts transformed with such vectors. The ACV synthetase gene can form part of a gene cluster that includes other genes involved in β-lactam biosynthesis and the production of penicillin. The expression of the entire biosynthetic gene cluster for the synthesis of penicillin from primary amino acids is also detailed in the patent. Suitable hosts for expression include heterologous hosts that are naturally non-producers of penicillin.
