This domain is found at the C-terminal end of a group of proteins predominantly found in Bacteroidetes, including Thiamin pyrophosphokinase from Bacteroides thetaiotaomicron. This protein consists of a N-terminal catalytic domain (Pfam:PF04263) and a C- terminal domain (this entry), which shows an structure mainly composed of beta-strands.	Domain

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 [1].
