Abstract excerpt
Clones carrying the gene encoding a proteinase were isolated from Clarke and Carbon's collection, using a chromogenic substrate, N-benzyloxycarbonyl-L-phenylalanine beta-naphthyl ester. The three clones isolated, pLC6-33, pLC13-1, and pLC36-46, shared the same chromosomal DNA region. A 0.9-kb Sau3AI fragment within this region was found to be responsible for the overproduction of the proteinase, and the...
