Abstract
The present invention relates to proteases obtained from a strain of Bacillus sp. AC13, and having (a) an apparent molecular weight of approximately 30 kD as determined by SDS-PAGE; (b) an isoelectric point of approximately 9.3 as determined by isoelectric focusing on LKB Ampholine PAG plates; (c) a pH optimum above 10 determined at 25.degree. C. with casein as substrate; (d) a temperature optimum in the range of 45.degree.-55.degree. C. determined at pH 9.5 with casein as substrate; and (e) immunochemical properties identical or partially identical to those of a protease derived from Bacillus sp. AC13, NCIMB No. 40482.
