Chymosin - Wikipedia

WebAspartic proteases (also "aspartyl proteases", "aspartic endopeptidases") are a catalytic type of protease enzymes that use an activated water molecule bound to one or more aspartate residues for catalysis of their peptide substrates. In general, they have two highly conserved aspartates in the active site and are optimally active at acidic pH.Nearly all … WebMany aspects of the structure of chymosin are quite unique even though structure comparisons indicate a high degree of structural homology with other eukaryotic aspartic proteinases.
