In the study of protein digestion and enzymatic activity, Trypsin and Alpha-Chymotrypsin are two proteases that are frequently discussed together. Both are serine proteases produced by the pancreas and are essential for breaking down proteins into smaller peptides. However, they exhibit distinct cleavage specificities, activation pathways, and are utilized in different research and industrial contexts.

Alpha-Chymotrypsin (CAS 9004-07-3) selectively cleaves peptide bonds on the C-terminal side of aromatic amino acids, namely tyrosine, phenylalanine, and tryptophan. This specificity is attributed to a hydrophobic pocket within its active site that favorably accommodates these bulky aromatic side chains. Its application in biochemical research for protein sequencing and structure analysis leverages this precise cleavage pattern.

Trypsin, on the other hand, cleaves peptide bonds on the C-terminal side of basic amino acids, primarily lysine and arginine. This difference in substrate specificity means that while both enzymes are proteases, they target different types of amino acid residues within a protein chain. This distinct targeting allows researchers to use them in complementary ways for comprehensive protein analysis.

Both enzymes are synthesized as inactive zymogens (chymotrypsinogen and trypsinogen) and are activated by other enzymes in the digestive system. Trypsinogen is activated by trypsin itself (autocatalysis) or by enteropeptidase, while chymotrypsinogen is activated by trypsin. This interdependency highlights the complex regulatory mechanisms within the body to prevent premature enzymatic activity.
