Physical and Chemical Properties | Chemical properties light red or light yellow freeze-dried powder, soluble in water, the optimum pH value is 7.0-7.5 (pig kidney, amylase) or 7-8 (mirotrase). Stability: pure enzyme can be preserved for a long time after freeze-drying. After toluene is added to the crude enzyme solution, it can be stored in the refrigerator for 1-2 days in a short period of time. Crude enzyme preparation can exist stably at 5 ℃. When pH is 7, the enzyme aqueous solution keeps its activity unchanged at 70 ℃ for 60min, and when pH is less than 5, it is rapidly inactivated at 70 ℃. Requirements for the chemical structure of the substrate: monocarboxyl amino acid; the amino group on the α-carbon atom in the amino acid is acylated, and the hydrolysis speed of the acylation group is different; the chemical structure of the substrate is different from the enzyme of different sources. Enzymatic reaction: N-acylated-L amino acid H2O; fatty acid anion L-amino acid. |
Use | Use to separate D-type and L-type amino acids. |
