WebSimilar properties were found for other “aspartyl proteinases,” such as chymosin (used in cheese making), some intracellular proteinases (cathepsins), and plant proteinases. After 1975, the three‐dimensional structures of pepsin and many of its relatives were determined by means of x‐ray diffraction techniques, greatly extending our ... WebJun 27, 2013 · The pH optima of pepsins have been stated as 2 while the pH optima of chymosin and fungal aspartic proteinases have been determined as 3–4 under common conditions (Foltmann 1999). Similarly, the observed values for pH stability may also depend on the experimental conditions. Chymosin is stable at pH values between 5.3 and 6.3.
