Fluorescence Changes Induced by Binding of 4-Pyridoxic Acid 5′-Phosphate to Proteins

Journal of Biological Chemistry, 1972
Abstract The affinity constant (Ka) and stoichiometry of binding of 4-pyridoxic acid 5'-phosphate (4-pyridoxic-5'-P) complexed to the protein bovine serum albumin and aspartate aminotransferase were investigated by fluorometric methods. Whereas bovine serum albumin binds 1 mole of 4-pyridoxic-5'-P per mole of protein with a Ka = 4.6 x 105 m-1, the ...

STUDIES ON ENZYMIC FORMATION OF 5'-O-(α-D-GLUCOPYRANOSYL)-4-PYRIDOXIC ACID IN RAT

Journal of Nutritional Science and Vitaminology, 1973
A new derivative of 4-pyridoxic acid was produced when 4-pyridoxic acid was incubated with homogenates of rat liver. The successful isolation procedures of the compound from the incubation mixture consisted of charcoal treatment and column chromatography on DEAE- and P-cellulose.
