Binding of a photoaffinity analogue of pyridoxal to pyridoxal kinase [PDF]
European Journal of Biochemistry, 1990 The binding of pyridoxal analogues to the structural domains of pyridoxal kinase was studied by fluorescence spectroscopy and chromatographic techniques. Two fragments of 24 and 16 kDa, arising from limited proteolysis of the native enzyme, were separated by ion‐exchange chromatography and used for binding studies with pyridoxal oxime.

The interactions between biogenic amines and pyridoxal, pyridoxal phosphate, and pyridoxal kinase
Archives of Biochemistry and Biophysics, 1972Abstract The effect of biogenic amines on pyridoxal kinase activity has been investigated in vitro . Experiments with a purified beef brain pyridoxal kinase indicate that 3,4-dihydroxyphenylalanine (dopa), dopamine, norepinephrine, and serotonin inhibit the reaction, while tyrosine, tryptophan, and 5-hydroxytryptophan (5-HTP) have no effect. However,

Pyridoxal 5'-phosphate (PLP), the catalytically active form of vitamin B6, plays a crucial role in several cellular processes. In most organisms, PLP is recycled from nutrients and degraded B6-enzymes in a salvage pathway that involves pyridoxal kinase (PLK), pyridoxine phosphate oxidase and phosphatase activities.

Fluorometric assay of pyridoxal and pyridoxal 5′-phosphate
Analytical Biochemistry, 1979Abstract A new and very sensitive fluorometric method for the determination of pyridoxal and pyridoxal 5′-phosphate is reported. The specificity is based on the reductive amination of pyridoxal and its 5′-phosphate with methyl anthranilate and sodium cyanoborohydride at pH 4,5 to 5,0.

Inhibition of gaba binding by pyridoxal and pyridoxal phosphate
International Journal of Biochemistry, 1980Abstract 1. 1. GABA exerts its neuroinhibitory effects by binding to a specific receptor on the post-synaptic membrane. 2. 2. Since both GABA and vitamin B 6 have been implicated in convulsion, the effects of B 6 vitamers on Na-independent binding of GABA was investigated by incubating synaptic membrane suspensions for 5 min at 4°C in 1 ml ...

We quantified pyridoxal 5'-phosphate (PLP), pyridoxal (PL), and 4-pyridoxic acid (PA) in the cerebrospinal fluid (CSF) of children and to investigate the effect of age, sex, epilepsy, and anti-epileptic drug (AED) therapy on these vitamers.CSF samples prospectively collected from 116 pediatric patients were analyzed. PLP, PL, and PA were measured using
