CC -!- FUNCTION: Catalyzes the ATP-dependent phosphorylation of thiamine-
CC monophosphate (TMP) to form thiamine-pyrophosphate (TPP), the active
CC form of vitamin B1. {ECO:0000255|HAMAP-Rule:MF_02128}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + thiamine phosphate = ADP + thiamine diphosphate;
CC Xref=Rhea:RHEA:15913, ChEBI:CHEBI:30616, ChEBI:CHEBI:37575,
CC ChEBI:CHEBI:58937, ChEBI:CHEBI:456216; EC=2.7.4.16;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_02128};
CC -!- PATHWAY: Cofactor biosynthesis; thiamine diphosphate biosynthesis;
CC thiamine diphosphate from thiamine phosphate: step 1/1.
CC {ECO:0000255|HAMAP-Rule:MF_02128}.
CC -!- MISCELLANEOUS: Reaction mechanism of ThiL seems to utilize a direct,
CC inline transfer of the gamma-phosphate of ATP to TMP rather than a
CC phosphorylated enzyme intermediate. {ECO:0000255|HAMAP-Rule:MF_02128}.
CC -!- SIMILARITY: Belongs to the thiamine-monophosphate kinase family.
CC {ECO:0000255|HAMAP-Rule:MF_02128}.
