Application

When immobilized using an insoluble porous support matrix such as agarose, Cibacron Blue 3GA is used for affinity chromatography purification of enzymes. This affinity has been attributed to a structural similarity between the dye and the natural ligands for proteins with cofactor binding domains.

Biochem/physiol Actions

Cibacron Blue 3GA is an anionic anthraquinone dye. It acts as a P2-purinoceptor antagonist and inhibits stimulus-evoked glutamate release by rat brain cortical tissue. Cibacron Blue 3GA inhibits OXA-1 and OXA-2 β-lactamases and was used to observe the binding of ligands to OXA-1 β-lactamase by monitoring tryptophan fluorescence.

Although beta-lactamases do not require any nucleotide co-substrates, the OXA-2 type is inhibited competitively by Cibacron Blue 3GA, and by other anthraquinone dyes, including some simpler compounds with no side chain. The enzyme causes a red shift in the spectrum

Evidence has previously been presented that P1 receptors for adenosine, and P2 receptors for nucleotides such as ATP, regulate stimulus-evoked release of biogenic amines from nerve terminals in the brain. Here we investigated whether adenosine and nucleotides exert presynaptic control

Class D beta-lactamases hydrolyze beta-lactam antibiotics by using an active site serine nucleophile to form a covalent acyl-enzyme intermediate and subsequently employ water to deacylate the beta-lactam and release product. Class D beta-lactamases are carboxylated on the epsilon-amino group of

A procedure is described to utilize blue dextran-Sepharose as an affinity chromatographic column specific for the super-secondary structure called the dinucleotide fold, which forms the binding sites for substrates and effectors on a wide range of proteins. The procedure can

1. Some postganglionic sympathetic axons possess P2Y-like P2-purinoceptors which, when activated, decrease the release of noradrenaline. We examined the question of whether such receptors also occur at the noradrenergic axons in the rat brain cortex. Slices of the brain cortex
