Radioimmunoassay for Glutamic Acid Decarboxylase-65

Diabetes Technology & Therapeutics, 1999
Glutamic acid decarboxylase-65 (GAD65), the enzyme that catalyzes the formation of gamma-aminobutyric acid (GABA), is the major autoantigen in both type 1 (insulin-dependent) diabetes and stiff-man syndrome (SMS). The observation that GAD65 autoantibodies may be present for years before the clinical onset of diabetes raises the question of when GAD65 ...

Glutamic Acid Decarboxylase Antibody

2014
Glutamic acid decarboxylase (GAD) catalyzes the conversion of glutamic acid into gamma-amino butyric acid within pancreatic islet β cells. Autoantibodies against GAD (GADA) are found in patients with type 1 diabetes mellitus (T1DM), stiff-person syndrome, and epilepsy.

Glutamic acid decarboxylase in Mycobacterium leprae

Archives of Microbiology, 1983
Suspensions of Mycobacterium leprae purified from the organs (mostly spleen) of experimentally-infected armadillos (Dasypus novemcinctus, Linn) decarboxylated 1-(14C) glutamic acid liberating 14CO2. The reaction was pyridoxal phosphate-dependent and was inhibited by hydroxylamine, suggesting that it is a true amino acid decarboxylase.

Inhibitors of crayfish glutamic acid decarboxylase

Neurochemical Research, 1984
Crayfish glutamic acid decarboxylase (GAD), like the homologous enzymes from other species, is inhibited by carbonyl-trapping agents (e.g. aminooxyacetic acid; AOAA) and sulfhydryl reagents (e.g. 5,5'-dithiobis-(2-nitrobenzoic acid); DTNB). It also is inhibited by the product GABA, many anions (e.g. SCN- and Cl-), and some cations (e.g. Zn+2).

Circular dichroism of L-glutamic acid decarboxylase

Biochemical and Biophysical Research Communications, 1967
Shukuya and Schwert (1960a) have shown that L-ylutamic acid decarboxylase (GAD) from E_. coli exhibits a sharply pHdependen,t reversible spectral change centered at pH 5.6. At pH's less than 5, the enzyme has an absorbance peak at 415 mp, while at pH's greater than 6, this peak is replaced by one at 340 mu.

Glutamic acid decarboxylase autoantibodies and neurological disorders

Neurological Sciences, 2002
Glutamic acid decarboxylase (GAD) is the enzyme that catalyses the production of GABA, a major neurotransmitter of the central nervous system. Antibodies to GAD (GAD-Ab) were first recognised in a patient affected by stiff-person syndrome; subsequently they were reported in a large number of cases with type 1 diabetes.

Encephalitis associated with glutamic acid decarboxylase autoantibodies

Neurology, 2001
Antiglutamic acid decarboxylase (GAD-A) autoantibodies were originally reported in patients with stiff-man syndrome (SMS).1 Successive studies have shown that GAD-A was implicated in the pathogenesis of type 1 diabetes.2 High titers of GAD-A were recently reported in neurologic patients with disorders other than SMS, in particular ataxia3,4⇓ and ...

Cerebellar ataxia with glutamic acid decarboxylase autoantibodies

Neurology, 1999
Degenerative cerebellar ataxia with autoantibodies against glutamic acid decarboxylase (GAD) is a rare disorder and may represent a subset of ataxias previously classified as idiopathic. The authors report a patient with progressive cerebellar ataxia, insulin-dependent diabetes mellitus, and GAD antibodies who responded to i.v. immunoglobulins.

Glutamate decarboxylase. Inhibition by monocarboxylic acids

Archives of Biochemistry and Biophysics, 1972
Abstract Aliphatic monocarboxylic acids are demonstrated to be substrate competitive inhibitors of bacterial glutamate decarboxylase. A chain-length effect is observed in the inhibition by the monocarboxylic acids with n -valeric acid functioning as the most effective inhibitor.
