Abstract
Recombinant host bacteria and plasmids for making the bacteria using recombinant DNA techniques are described. The plasmids contain DNA coding for subtilisin with an amino acid substitution. Expression of the plasmid DNA results in production of a modified subtilisin.
Claims2
A recombinant expression vector comprising DNA encoding a subtilisin having a site specific mutation at any one of the amino acid residues equivalent to -1, +32, +155, +104, +222, +166, +64, +33, +169, +189, +217, +156, +221 or +152 in the corresponding amino acid sequence of the mature subtilisin naturally produced by Bacillus amyloliquefaciens as shown in FIG. 1B.
