Application

L-Glutamic acid γ-monohydroxamate has been used as a standard to calculate transglutaminase (TGase) activity.

Biochem/physiol Actions

L-Glutamic acid γ-monohydroxamate [L-Glu(gamma)HXM] is used as a vanadium ligand which potentiates vanadiums metabolic activity. L-Glu(gamma)HXM is also used as a substrate for E. coli asparagine synthetase B and as an ATP-dependent irreversible inhibitor of Escherichia coli gamma-glutamylcysteine synthetase.

In maize (Zea mays L.), GSp1, the predominant GS isozyme of the developing kernel, is abundant in the pedicel and pericarp, but absent from the endosperm and embryo. Determinations of GSp1 tissue distribution in vegetative tissues have been limited thus

The equilibria of copper(II) with (S)-glutamic-gamma-hydroxamic acid (H2L) were investigated in aqueous solution by different techniques: glass electrode potentiometry; calorimetry; VIS and CD spectrophotometry; and ES-MS. An unexpected pentacopper(II) 12-metallacrown-4 [Cu5L4H(-4)](2-) was detected, analogous to those well known formed by

Several ligands, when complexed with vanadium, potentiate its insulinomimetic activity both in vivo and in vitro. We have recently found that L-Glu-gamma-monohydroxamate (HXM) and L-Asp(beta)HXM were especially potent in this regard. In the present study, we used vanadium-enriched adipose cells

Incubation of Escherichia coli gamma-glutamylcysteine synthetase with L-glutamic acid gamma-monohydroxamate and ATP caused slow but irreversible inhibition of the enzyme, and more than 90% activity was lost in three days. The enzyme was not inactivated when ATP was absent or

The method for the assay of glutamine synthetase (GlnS) relies on the gamma-glutamyl transferase reaction, i.e. the formation of glutamyl-gamma-hydroxamate from glutamine and hydroxylamine, and the chromatographic separation of the reaction product from the reactants. The method is not only
