substrate specificity

Protein-directed evolution achieves continuous optimization of catalytic activity, stability, and substrate specificity through repeated cycles of gene diversification, variant expression, functional screening, and enrichment of beneficial mutations, without relying completely on prior knowledge ...

Ribonucleases cleave RNA by recognizing specific bases, nucleic acid hybrid structures, or double-stranded RNA conformations, and have distinct application positions in nucleic acid purification, structural analysis, gene regulation, and disease mechanism research.

Chymotrypsin (commonly referring to alpha-chymotrypsin) is a canonical pancreatic serine protease. Common laboratory preparations are typically purified from bovine or porcine pancreas and are frequently described commercially as “alpha-chymotrypsin from bovine pancreas” (CAS 9004-07-3). ...

Proteases are enzymes that catalyze the hydrolysis of peptide bonds in proteins or polypeptides. In life-science research, they are widely used for proteomics digestion, limited proteolysis for domain mapping, deproteinization of nucleic-acid samples, antibody fragmentation, and ...
