A Novel Mutation of SLC19A2 in a Chinese Zhuang Ethnic Family with Thiamine-Responsive Megaloblastic Anemia

open access: yesCellular Physiology and Biochemistry, 2018
Background/Aims: Thiamine-responsive megaloblastic anemia syndrome is a rare autosomal recessive disorder resulting from mutations in SLC19A2, and is mainly characterized by megaloblastic anemia, diabetes, and progressive sensorineural hearing loss ...

The vitamin B1 metabolism of Staphylococcus aureus is controlled at enzymatic and transcriptional levels. [PDF]

open access: yesPLoS ONE, 2009
Vitamin B1 is in its active form thiamine pyrophosphate (TPP), an essential cofactor for several key enzymes in the carbohydrate metabolism. Mammals must salvage this crucial nutrient from their diet in order to complement the deficiency of de novo ...

Pathway of thiamine pyrophosphate synthesis in Micrococcus denitrificans [PDF]

open access: yesJournal of Bacteriology, 1976
The pathway of thiamine pyrophosphate (TPP) biosynthesis, which is formed either from exogeneously added thiamine or from the pyrimidine and thiazole moieties of thiamine, in Micrococcus denitrificans was investigated. The following indirect evidence shows that thiamine pyrophosphokinase (EC 2.7.6.2) catalyzes the synthesis of TPP from thiamine: (i ...

Perturbations in histidine biosynthesis uncover robustness in the metabolic network of Salmonella enterica. [PDF]

open access: yesPLoS ONE, 2012
Phosphoribosylamine (PRA) is an intermediate in the biosynthetic pathway that is common to thiamine and purines. Glutamine phosphoribosyl pyrophosphate (PRPP) amidotransferase is the product of the purF gene in Salmonella enterica and catalyzes the ...

Pathway Editing Targets for Thiamine Biofortification in Rice Grains

open access: yesFrontiers in Plant Science, 2018
Thiamine deficiency is common in populations consuming polished rice as a major source of carbohydrates. Thiamine is required to synthesize thiamine pyrophosphate (TPP), an essential cofactor of enzymes of central metabolism. Its biosynthesis pathway has

Biosynthetic Pathway of Thiamine Pyrophosphate: a Special Reference to the Thiamine Monophosphate-Requiring Mutant and the Thiamine Pyrophosphate-Requiring Mutant of Escherichia coli [PDF]

open access: yesJournal of Bacteriology, 1972
Two types of mutants of Escherichia coli were isolated, one of which (mutant 70-23-107) responded to thiamine pyrophosphate, and the other (mutant 70-23-102) to thiamine monophosphate and thiamine pyrophosphate. They were produced by further mutation of a thiamine auxotroph of E.

Evaluation of thiamine as adjunctive therapy in COVID-19 critically ill patients: a two-center propensity score matched study

open access: yesCritical Care, 2021
Background Thiamine is a precursor of the essential coenzyme thiamine pyrophosphate required for glucose metabolism; it improves the immune system function and has shown to reduce the risk of several diseases.

Thiamine Is Required for Virulence and Survival of Pseudomonas syringae pv. tomato DC3000 on Tomatoes

open access: yesFrontiers in Microbiology, 2022
Pseudomonas syringae pv. tomato DC3000 (PstDC3000) is an important plant pathogen that infects tomatoes and Arabidopsis. Thiamine and its derivative thiamine pyrophosphate (TPP) are cofactors that play an important role in the growth and survival of many
