Inactivation of Rhodanese by Pyridoxal 5′‐Phosphate

European Journal of Biochemistry, 1975
Pyridoxal 5′‐phosphate and other aromatic aldehydes inactivate rhodanese. This inactivation reaches higher extents if the enzyme is in the sulfur‐free form. The identification of the reactive residue as an amino group has been made by spectrophotometric determination of the 5′‐phosphorylated pyridoxyl derivative of the enzyme.

Thermodynamics properties of pyridoxal 5 phosphate

Journal of Solution Chemistry, 1986
The ionization constants and heats of ionization of pyridoxal 5′ phosphate groups in the pH range 2–10 have been determined by potentiometric and calorimetric techniques at 20, 25, 30, and 37°C in 0.1M KCl.

[78] Immobilization of pyridoxal 5′-phosphate and pyridoxal 5′-phosphate-dependent enzymes on sepharose

1979
Publisher Summary The immobilization of pyridoxal 5'-phosphate (PLP) and pyridoxal 5'-phosphate-dependent enzymes on Sepharose is described in this chapter. Immobilized derivatives of PLP (pyridoxal 5'-phosphate) may be useful for the purification by the affinity chromatography of enzymes requiring this coenzyme.

Polarographic behaviour of pyridoxal 5′-phosphate

J. Chem. Soc., Perkin Trans. 2, 1977
The polarographic reduction of pyridoxal 5′-phosphate in several NN-dimethylformamide–water mixtures has been investigated. It has been found that one, two, or three waves appear depending on the experimental conditions. The dependence of their half-wave potentials and the variation of their intensities with pH for each solvent were studied.

Pyridoxal 5-Phosphate and Calcium Channels

2000
The BAY K 8644 -induced influx of 45Calcium into intracellular compartment of artery segments of normal rats was blocked by pyridoxal phosphate (PLP) as well as by the dihydropyridine-sensitive calcium channel antagonists (CCA). PLP also decreased bindingin vitroof CCA to membrane preparations from normal vascular tissue.

Pyridoxal–5′–Phosphate and Alkaline Phosphatase

Hepatology, 1986
Markedly increased circulating concentrations of pyridoxal–5′–phosphate (PLP) were found in each of 14 patients representing all clinical forms of hypophosphatasia, an inborn error characterized by deficient activity of the tissue–nonspecific (bone/liver/kidney) isoenzyme of alkaline phosphatase (AP).

Design of Pyridoxal 5"-Phosphate Dependent Catalytic Antibodies

Biochemistry (Moscow), 2002
Modern approaches for developing antibodies with coenzyme-dependent activities are discussed for pyridoxal 5'-phosphate dependent transformation of amino acid as an example. A new type of antigens analogous to enzyme--substrate compounds is suggested for the production of such antibodies.
