英文摘要
The amino acid composition of halophilic enzymes is in general characterized by an abundant content of acidic amino acid leading to high aqueous solubility without aggregation in both native and denatured states and hence allowing efficient renaturation of halophilic proteins after heat or denaturant treatment. The replacement of neutral or basic amino acid residues in non-halophilic proteins with acidic amino acid residues converted non-halophilic to halophilic proteins which show higher aqueous solubility and stability.
