Function
function
Catalyzes the ATP-dependent phosphorylation of thiamine-monophosphate (TMP) to form thiamine-pyrophosphate (TPP), the active form of vitamin B1.
Miscellaneous
Reaction mechanism of ThiL seems to utilize a direct, inline transfer of the gamma-phosphate of ATP to TMP rather than a phosphorylated enzyme intermediate.
Catalytic activity
- ATP + thiamine phosphate = ADP + thiamine diphosphate
Pathway
Cofactor biosynthesis; thiamine diphosphate biosynthesis; thiamine diphosphate from thiamine phosphate: step 1/1.
