摘要

A mutant protease for use in detergents has at least 70% homology with the aminoacid sequence of PB92 serine protease (I), but differs by at least one residue at a site corresponding to the following positions in the PB92 serine protease 99, 102, 116, 126, 127, 128, 130, 160, 203, 211 and 212. The new protease has improved wash performance and/or improved stability relative to the PB92 serine protease.
