Adenosine 5′-monophosphate Agarose (5′-AMP agarose) has been used in affinity chromatography to isolate β and gamma glutamate decarboxylase, which is important for controlling gamma-aminobutyric acid (GABA) synthesis in brain.
We present a method for preparing human liver lactate dehydrogenase (L-lactate:NAD+ oxidoreductase; EC 1.1.1.27) isoenzyme-5 by sequential ion-exchange chromatography, general-ligand (AMP analog) affinity chromatography, and preparative isoelectric focusing. The yield ws 40%, with a 493-fold purification. The final specific activity

Trypanosomes have no de novo purine biosynthesis and thus depend upon salvage pathways to obtain purines for their metabolic pathways and for the biosynthesis of nucleic acids. An inosine-adenosine-guanosine preferring nucleoside hydrolase (IAG-nucleoside hydrolase) from the African trypanosome Trypanosoma brucei

We describe the purification of a H2O-producing NADH oxidase from the protozoan parasite Giardia duodenalis. The enzyme is a monomeric flavoprotein containing flavin adenine dinucleotide in a 1:1 molar ratio with the polypeptide. The NADH oxidase has an apparent molecular

The interactions of two forms of porcine brain glutamate decarboxylase (beta-GAD and gamma-GAD) with the effector ATP were studied by affinity chromatography. A third form, alpha-GAD, was only slightly retarded by the affinity matrix and was eluted in the buffer

A major regulatory feature of brain glutamate decarboxylase (GAD) is a cyclic reaction that controls the relative amounts of holoenzyme and apoenzyme [active and inactive GAD with and without bound pyridoxal 5'-phosphate (pyridoxal-P, the cofactor), respectively]. Previous studies have indicated
