>gnl|CDD|146743 pfam04265, TPK_B1_binding, Thiamin pyrophosphokinase, vitamin B1 binding domain. Family of thiamin pyrophosphokinase (EC:2.7.6.2). Thiamin pyrophosphokinase (TPK) catalyses the transfer of a pyrophosphate group from ATP to vitamin B1 (thiamin) to form the coenzyme thiamin pyrophosphate (TPP). Thus, TPK is important for the formation of a coenzyme required for central metabolic functions. The structure of thiamin pyrophosphokinase suggest that the enzyme may operate by a mechanism of pyrophosphoryl transfer similar to those described for pyrophosphokinases functioning in nucleotide biosynthesis.
