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.

The plant enzyme S-adenosylmethionine:methionine S-methyltransferase (EC 2.1.1.12, MMT) catalyzes the synthesis of S-methylmethionine. MMT was purified 620-fold to apparent homogeneity from leaves of Wollastonia biflora. The four-step purification included fractionation with polyethylene glycol, affinity chromatography on adenosine-agarose, anion exchange chromatography

1. Glutamate decarboxylase is a focal point for controlling gamma-aminobutyric acid (GABA) synthesis in brain. Several factors that appear to be important in the regulation of GABA synthesis have been identified by relating studies of purified glutamate decarboxylase to conditions
The mosquito homolog of mammalian DNA polymerase epsilon, formerly known as a proliferating cell nuclear antigen (PCNA)-independent form of DNA polymerase delta, has been purified from mosquito larval extracts. The polymerase epsilon was separated from DNA polymerase alpha by chromatography

Streptomyces cattleya is unusual in that it produces fluoroacetate and 4-fluorothreonine as secondary metabolites. We now report the isolation of an NAD(+)-dependent fluoroacetaldehyde dehydrogenase from S. cattleya that mediates the oxidation of fluoroacetaldehyde to fluoroacetate. This is the first enzyme
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
