TPK1, also known as thiamin pyrophosphokinase 1, catalyzes the phosphorylation of thiamine to thiamine pyrophosphate. This protein can also catalyze the phosphorylation of pyrithiamine to pyrithiamine pyrophosphate. Source: Recombinant protein corresponding to aa1-243 of human TPK1, fused to His-tag at N-terminal expressed in E. coli.
