Isolation, Purification and Characterization of new cold active subtilisin-like protease from Bacillus sp. strain EL-GU1

Abstract

Proteases are hydrolytic enzymes that slice peptide bonds between amino acid residues and these enzymes have various industrial applications including detergent, food, pharmaceutical, leather and diagnostic reagent industries. Among them, alkaline proteases, the most commercialized enzymes in the industry, are of particular interest due to their potential applications in the detergent industry as cleaning additives. In this study, a novel alkaline protease from Bacillus sp. strain EL-GU1 was reported showing highest activity at pH 6 and 25°C. The novel protease was purified by using ammonium sulfate precipitation and identified by 16S rDNA sequencing. Highest activity was observed as 3300 µmol/min-1mg-1 when casein used as a substrate. Kinetic parameters of the enzyme were determined; KM, Vmax, kcat and catalytic efficiency values were calculated as 1.4 mM, 1 mM/s, 2.10-7 s-1, 0.14 10-7 s-1M-1, respectively. These results indicated that the novel cold active protease from Bacillus sp. strain EL- GU1 can be a good candidate for the detergent industry
