title: The conversion of 3-Hydroxy-2,4,5-trihydroxymethylpyridine into pyridoxine by Kloeckera apiculata.
abstract: Kloeckera apiculata, a vitamin B-6-dependent yeast, grows in the presence of 3-hydroxy-2,4,5-trihydroxymethylpyridine in vitamin B-6-free media. On a molar basis the growth-promoting activity of this compound is approximately one-tenth that of other forms of vitamin B-6. [G-3H]3-Hydroxy-2,4,5-trihydroxymethylpyridine is converted into radioactive vitamin B-6 compounds of the same specific radioactivity by growing cultures of K. apiculata.
