Reaction: TDPK phosphorylates ThDP to ThTP
- in pathway: Vitamin B1 (thiamin) metabolism
Thiamin triphosphate (ThTP) is believed to be synthesized from thiamin diphosphate (ThDP), catalyzed by ThDP kinase (TDPK), an enzyme that remains poorly characterized (Nishino et al, 1983).
Reaction - small molecule participants:
ThTP [cytosol]
ADP [cytosol]
ATP [cytosol]
