Abstract
There are described certain DNA sequences which encode subtilisins wherein the amino acid sequence of such substilisins has been modified at a position equivalent to +225 in Bacillus amyloliquefaciens, such that an amino acid selected from the group consisting of alanine, leucine, methionine, glutamine, valine and serine, has been substituted for the amino acid residues naturally occuring at such position.
