1. A subtilisin variant comprising an amino acid sequence comprising an amino acid substitution of T77N-G165Q, wherein said variant has at least 90% amino acid sequence identity to the amino acid sequence of a parent subtilisin comprising the amino acid sequence of SEQ ID NO:2, wherein the amino acid positions of the variant are numbered by correspondence with the amino acid sequence of SEQ ID NO:2, wherein the variant has protease activity measured by hydrolysis of N-succinyl-alanine-alanine-proline-phenylalanine-p-nitroanilide (N-suc-AAPF-pNA) or dimethyl casein substrate, and wherein the variant has improved stability in a boron-free detergent when compared to stability in a boron-free detergent of said parent subtilisin.
