Thiamine pyrophosphate (TPP) is a required cofactor in Salmonella typhimurium that is generated de novo by the condensation of 4-amino-5-hydroxymethyl pyrimidine (HMP) pyrophosphate and 4-methyl-5-(beta-hydroxyethyl)-thiazole (THZ) monophosphate. The THZ and HMP moieties are independently synthesized, and labeling studies have demonstrated
The thiamine requirement for growth of Eikenella corrodens was investigated. Autoclaved thiamine at a concentration of 1.0 microgram/ml supported maximal growth whereas for the same growth, filter-sterilized thiamine was required at 50-100 micrograms/ml. Studies with two thiamine degradation products, 2-methyl-4-amino-5-hydroxymethylpyrimidine

Thiamine pyrophosphate is an essential cofactor that is synthesized de novo in Salmonella typhimurium. The biochemical steps and gene products involved in the conversion of aminoimidazole ribotide (AIR), a purine intermediate, to the 4-amino-5-hydroxymethyl-2-methyl pyrimidine (HMP) moiety of thiamine have
Amiloride (Am) inhibits growth in the fission yeast Schizosaccharomyces pombe. We show that the toxic effect of this drug is relieved by low concentrations of thiamine (Th) and that the pyrimidine moiety of the Th molecule is responsible for growth
Biosynthesis of thiamin thiazole: determination of the regiochemistry of the S/O acyl shift by using 1,4-dideoxy-D-xylulose-5-phosphate.
