Pyridoxine (PN) is a metabolic precursor of pyridoxal phosphate that functions as a cofactor of many enzymes in amino acid metabolism. PN, pyridoxal, and pyridoxamine are collectively referred to as vitamin B6, and mammalian organisms depend on its uptake from the diet. In addition to the ability to use extracellular vitamin B6, most unicellular organisms are also capable of synthesizing PN to generate pyridoxal phosphate. Here, we report the isolation of Saccharomyces cerevisiae mutants that… CONTINUE READING
