construction of hybrid beta-glucanase enzyme H1 which contains the 107 amino-terminal residues of mature Bacillus amyloliquefaciens beta-glucanase and the 107 carboxyl-terminal amino acid residues of Bacillus beta-glucanase. Hybrid enzyme H2 consists of the 105 amino-terminal residues from the Bacillus macerans enzyme and the carboxyl-terminal 107 amino acids from Bacillus amyloliquefaciens. Hybrid enzyme H1 exhibits increased thermostability especially in an acidic environment compared to both parental enzymes. Hybrid enzyme H2 is more thermolabile than the naturally occuring beta-glucanases

modifying five (out of 12) epsilon-amino groups in lysine residues with nitrous acid improves thermostablility and enzymatic activity of the enzyme, optimizing the condition of chemical modification, overview. Compared to the wild-type enzyme, the optimally-modified enzyme has higher specific activity and T50 value, which are 3370 U/mg and 70°C, respectively. Its half-life values at 50 and 60°C are extended and reach 58.5 and 49.5 min, respectively
