Hepatic glutaminase expression: relationship to kidney‐type glutaminase and to the urea cycle
The FASEB Journal, 1993Glutamine functions as a major transport form of nitrogen and carbon within the body. In the liver, glutamine is hydrolyzed by a unique liver‐type, phosphate‐activated glutaminase, and the end products of hepatic glutamine catabolism are glucose and urea. Other tissues possess a different, kidney‐type, glutaminase isozyme.

[Characteristics of Triticale glutaminase].
Prikladnaia biokhimiia i mikrobiologiia, 2002The glutaminase (EC 3.5.1.2) isolated from seedlings of triticale (Triticale sp.) had a pH optimum of about 8, was inhibited with excess substrate (glutamine), and reaction products (glutamate and NH4+). A monovalent anion (Cl-) and a multivalent anion (phosphate) were shown to activate the glutaminase.

[134] Glutaminase (Escherichia coli)
1970Publisher Summary This chapter presents the assay, purification, and properties of glutaminase. A significant amount of glutamic acid (with an undissociated carboxyl group) exists in equilibrium with glutamate ion in the pH range of enzyme activity.
