A newly isolated Bacillus species, which grew optimally at 30ยฐC and pH 10, produced a carboxymethylcellulase in a medium containing 10 g CM-cellulose/l. The enzyme, when partially purified by gel filtration, had a mass of about 29 kDa as determined by both SDS-PAGE and gel filtration chromatography.
To obtain a new serine protease from alkalophilic Bacillus sp. NKS-21, shotgun cloning was carried out. As a result, a new protease gene was obtained. It encoded an intracellular serine protease (ISP-1) in which there was no signal sequence. The molecular weight was 34,624. The protease showed about
