Abstract Periplasmic soluble thiamin-binding protein in Saccharomyces cerevisiae (Iwashima, A. et al. (1979) Biochim. Biophys. Acta 577, 217–220) was demonstrated to be encoded by PHO3 gene that codes for thiamin repressible acid phosphatase (Schweingruber, M.E. et al. (1986) J. Biol. Chem. 261, 15877–15882) by genetic analysis. The pho3 mutant cells of S. cerevisiae in contrast to the parent cells have markedly reduced activity of the uptake of [14C]thiamin phosphates, suggesting that thiamin repressible acid phosphatase plays a role in the hydrolysis of thiamin phosphates in the periplasmic space prior to the uptake of their thiamin moieties by S. cerevisiae.
