Short name: TPK_catalytic_sf

Overlapping entries


Thiamin pyrophosphokinase (TPK, EC: catalyzes 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 the thiamin pyrophosphokinase catalytic domain is composed of three layers (alpha/beta/alpha) with parallel beta-sheet of six strands. This structure suggests that the enzyme may operate by a mechanism of pyrophosphoryl transfer similar to those described for pyrophosphokinases functioning in nucleotide biosynthesis [PMID: 11435118].
