General description

L-arginase is also called as L-arginine amidinohydrolase. It exists in two forms, such as arginase-1 and arginase-2. Arginase-1 is present in liver cells and arginase-2 is seen usually in extrahepatic tissues like, kidney, brain, skeletal muscle, small intestine and the lactating mammary gland. Arginase -2 is mapped to human chromosome 14q24.1−24.3.

Biochem/physiol Actions

L-arginase hydrolyze L-arginine into L-ornithine and urea, which is the last step of the urea cycle in the liver of ureotelic species. Arginase plays a major role in the mammalian immune system and the enzyme participates in several aspects of inflammation.
L-Arginase is the major degradative enzyme for arginine; converts arginine to ornithine.
L-Arginase is the major degradative enzyme for arginine; converts arginine to ornithine; deficiency is associated with spasticity and motor dysfunction.

Other Notes

One unit will cause the hydrolysis of 1.0 μmole of L-arginine per minute at pH 9.5 and 37 °C.

Questions

  1. I want to use this enzyme at a neutal pH, could you please comment on the activity and how much reduction in enzyme activity and specificity would be happening due to the change in the pH?

    1 answer

    1. L-Arginase typically exhibits optimal activity at pH 9.5 and 37 °C. While the product is likely to retain some degree of potency, the enzymatic activity of this material at neutral pH has not been determined. The enzyme is known to be rapidly inactivated at pH values below 6, according to "The Reversible Inactivation of Rat-Liver Arginase at Low pH". Please see the link below, Figure 1, which shows the Inactivation of arginase at different pH values:

      Please see the link below to review an additional article highlighting the relationship between pH and mouse liver arginase.
