Abstract

The present invention is related to variants of fungal serine protease enzyme, which have serine protease activity of Malbranchea protease. Also disclosed are isolated nucleic acid molecules, comprising polynucleotide sequences which encode variants of fungal serine protease enzyme, nucleic acid sequences encoding said protease variants, a host cell and a process of producing polypeptides having serine protease activity. Said protease variants are useful as enzyme preparations applicable in detergent compositions and for treating fibers, wool, hair, leather, or silk, for treating food or feed, or for any applications involving modification, degradation or removal of proteinaceous material.
