Abstract
There are described certain subtilisins wherein the amino acid sequence of such subtilisins 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 residue naturally occurring at such position.
