tThe endoglucanase gene EG5B of 1611 bp with a predicted molecular weight of 58.6 kDa from Paenibacillussp. IHB B 3084 was cloned and expressed in Escherichia coli BL21(DE3). The analysis of deduced amino acidsequence revealed a modular structure of the endoglucanase EG5B with an N-terminal catalytic domainof glycosyl hydrolase family 5 and a C-terminal carbohydrate-binding module of family 3. The purifiedenzyme showed high hydrolytic activity on carboxymethylcellulose, low activity on p-nitrophenyl -d-cellobioside, avicel and filter paper, and no activity on microcrystalline cellulose, p-nitrophenyl -d-glucoside, cellobiose and salicin as substrates. The enzyme was mild-alkaline active with optimum activity at pH 7–8 and stable over broad pH range. The temperature optimum was at 50◦C with >50%activity over 30–60◦C. The enzyme stability with >63% residual activity towards non-ionic and anionic surfactants and commercial detergents suggested its compatibility as an additive to detergents. Not Available |
