ABSTRACT:
DNA sequences obtained from S. clavuligerus, recombinant vectors incorporating such sequences and hosts transformed with such vectors are disclosed. The DNA comprises one or more genes encoding one or more enzymes involved in the biosynthesis of clavulanic acid and may be used to improve the yield of clavulanic acid produced by clavulanic acid-producing organisms such as S. clavuligerus ATCC 27064.
