Microbial hydrolytic enzymes: In silico studies between polar and tropical regions
Enzyme is important as biocatalyst for industrial and biotechnological applications. Cold active enzymes have showed many advantages compare to mesophilic enzymes. Their cold active and thermolabile characteristics have shown potential benefits in many industries. In silico characterization of hydro...

Enzyme is important as biocatalyst for industrial and biotechnological applications. Cold active enzymes have showed many advantages compare to mesophilic enzymes. Their cold active and thermolabile characteristics have shown potential benefits in many industries.

Amino acid sequences and molecular structures of mesophilic and psychrophilic bacterial enzyme homologues were compared thoroughly. Amino acid sequences from these two homologs do not showed any extraordinary differences.

Active site residues located in catalytic domain of both psychrophilic and mesophilic enzymes were highly conserved.
