The yeast Saccharomyces cerevisiae is able to synthesize thiamin pyrophosphate (TPP) de novo, which involves the independent… Expand

Thiamin pyrophosphate is an essential coenzyme in all organisms that depend on fermentation, respiration or photosynthesis to… Expand

Bacillus subtilis gene products TenA and TenI have been implicated in regulating the production of extracellular proteases, but… Expand

Saccharomyces cerevisiae Thi20 is a fusion protein with homology to Bacillus subtilis ThiD and TenA. The N-terminus of Thi20 has… Expand

A genetic screen was developed for the identification of genes related to thiamin biosynthesis and degradation. Genes conferring… Expand

The conversion of 5-aminoimidazole ribonucleotide (AIR) into 4-amino-2-methyl-5-hydroxymethylpyrimidine (HMP) is a fascinating… Expand

The thiA gene is involved in the biosynthesis of the pyrimidine moiety of thiamin in Bacillus subtilis. This gene was cloned… Expand
