Protein

Thiamin pyrophosphokinase 1

Gene

Tpk1

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the phosphorylation of thiamine to thiamine pyrophosphate. Can also catalyze the phosphorylation of pyrithiamine to pyrithiamine pyrophosphate.2 Publications

Catalytic activityi

ATP + thiamine = AMP + thiamine diphosphate.

Pathwayi: thiamine diphosphate biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes thiamine diphosphate from thiamine.
Proteins known to be involved in this subpathway in this organism are:
  1. Thiamin pyrophosphokinase 1 (Tpk1)
This subpathway is part of the pathway thiamine diphosphate biosynthesis, which is itself part of Cofactor biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes thiamine diphosphate from thiamine, the pathway thiamine diphosphate biosynthesis and in Cofactor biosynthesis.
