The photophysical properties and acid/base equilibria of 4-pyridoxic acid ( 3-hydroxy-5-(hydroxymethyl)-2-methylpyridine-4-carboxylic acid), the final product of the catabolism of vitamin B 6 , have been studied in aqueous solutions. The ground state of 4-pyridoxic acid exhibits the different proton
Wood et al. (1) investigated a tryptophanase preparation obtained from Escherichiu coli, and found that it converted tryptophan to indole, pyruvate, and ammonia, and that pyridoxal phosphate was needed as a coenzyme for the reaction. Utilizing this reaction, Wada et nl. (2) determined the amount of
