Invertase Suc2-mediated inulin catabolism is regulated at the transcript level in Saccharomyces cerevisiae

BACKGROUND Invertase Suc2 was recently identified as a key hydrolase for inulin catabolism in Saccharomyces cerevisiae, whereas the Suc2 activity degrading inulin varies greatly in different S. cerevisiae strains. The molecular mechanism causing such variation remained obscure. The aim of this study is to investigate how Suc2 activity is regulated in S. cerevisiae. RESULTS The effect of SUC2 ...

Methionine catabolism in Saccharomyces cerevisiae.

The catabolism of methionine to methionol and methanethiol in Saccharomyces cerevisiae was studied using (13)C NMR spectroscopy, GC-MS, enzyme assays and a number of mutants. Methionine is first transaminated to alpha-keto-gamma-(methylthio)butyrate. Methionol is formed by a decarboxylation reaction, which yields methional, followed by reduction. The decarboxylation is effected specifically by ...

A spacer protein in the Saccharomyces cerevisiae spindle poly body whose transcript is cell cycle-regulated

Monoclonal antibodies against the 110-kD component of the yeast spindle pole body (SPB) were used to clone the corresponding gene SPC110. SPC110 is identical to NUF1 (Mirzayan, C., C. S. Copeland, and M. Synder. 1992. J. Cell Biol. 116:1319-1332). SPC110/NUF1 has an MluI cell cycle box consensus sequence in its putative promoter region, and we found that the transcript was cell cycle regulated ...

Cisplatin cytotoxicity is dependent on mitochondrial respiration in Saccharomyces cerevisiae

Objective(s): To understand the role of mitochondrial respiration in cisplatin sensitivity, we have employed wild-type and mitochondrial DNA depleted Rho0 yeast cells. Materials and Methods: Wild type and Rho0 yeast cultured in fermentable and non-fermentable sugar containing media, were studied for their sensitivity against cisplatin by monitoring growth curves, oxygen consumption, pH changes ...
