thiamine pyrophosphate (tpp or thpp), or thiamine diphosphate (thdp), or cocarboxylase[1] is a thiamine (vitamin b1) derivative which is produced by the enzyme thiamine diphosphokinase. thiamine pyrophosphate is a cofactor that is present in all living systems, in which it catalyzes several biochemical reactions.
thiamine pyrophosphate is synthesized in the cytosol and is required in the cytosol for the activity of transketolase and in the mitochondria for the activity of pyruvate-, oxoglutarate- and branched chain keto acid dehydrogenases. to date, the yeast thpp carrier (tpc1p) the human tpc and the drosophila melanogaster have been identified as being responsible for the mitochondrial transport of thpp and thmp.it was first discovered as an essential nutrient (vitamin) in humans through its link with the peripheral nervous system disease beriberi, which results from a deficiency of thiamine in the diet.
