Ph of trypsin enzyme
WebMar 4, 2024 · The pH optimum of trypsin is 7 - 9. 10 Assay Method 11 The activity of most preparations is determined by a continuous rate spectrophotometric assay and expressed in BAEE units. Unit Definition: One BAEE unit will produce a ΔA 253 of 0.001 per min at pH 7.6 at 25 °C using BAEE as substrate. Reaction volume = 3.2 mL (1 cm light path). Conditions WebTrypsin: Preferentially cleaves at Arg and Lys in position P1 with higher rates for Arg ( Keil, 1992 ), especially at high pH (but treated equally in the program). Pro usually blocks the action when found in position P1', but not when Lys is in position P1 and Trp is in position P2 at the same time.
