Abstract The gene for a highly alkaline pectate lyase, Pel-4A, from alkaliphilic Bacillus sp. strain P-4-N was cloned, sequenced, and overexpressed in Bacillus subtilis cells. The deduced amino acid sequence of the mature enzyme (318 amino acids, 34 805 Da) showed moderate homology to those of known pectate lyases in the polysaccharide lyase family 1. The purified recombinant enzyme had an isoelectric...
Abstract The cleaning power of detergents seems to have peaked; all detergents contain similar ingredients and are based on similar detergency mechanisms. To improve detergency, modern types of heavy-duty powder detegents and automatic dishwasher detergents usually contain one or more enzymes, such as protease, amylase, cellulase, and lipase. Alkaliphilic Bacillus strains are often good sources of...
