Thiamine, thiaminepyrophosphate and 4-methyl-5-beta-oxyethylthiazole are studied for their effect on the acetylcholinesterase activity in the brain, blood plasma and cells. The activity of acetylcholinesterase in blood cells is shown to be inhibited most of all by thiamine and thiazole. Acetylcholinesterase

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

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
E Webb et al.
Journal of bacteriology, 179(13), 4399-4402 (1997-07-01)
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
