RT "Thiamin pyrophosphokinase is required for thiamin cofactor activation in
RT Arabidopsis.";
RL Plant Mol. Biol. 65:151-162(2007).
CC -!- FUNCTION: Catalyzes the phosphorylation of thiamine to thiamine
CC pyrophosphate (TPP) (PubMed:17611796). TPP is an active cofactor for
CC enzymes involved in glycolysis and energy production (PubMed:17611796).
CC Plant leaves require high levels of TPP for photosynthesis and
CC carbohydrate metabolism (PubMed:17611796).
CC {ECO:0000269|PubMed:17611796}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + thiamine = AMP + H(+) + thiamine diphosphate;
CC Xref=Rhea:RHEA:11576, ChEBI:CHEBI:15378, ChEBI:CHEBI:18385,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:58937, ChEBI:CHEBI:456215; EC=2.7.6.2;

CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:11577;
CC Evidence={ECO:0000269|PubMed:17611796};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=1.28 uM for thiamine {ECO:0000269|PubMed:17611796};
CC Vmax=9.6 pmol/min/mg enzyme with thiamine as substrate
CC {ECO:0000269|PubMed:17611796};
CC pH dependence:
CC Optimum pH is 7. Active between pH 6 and pH 8.
CC {ECO:0000269|PubMed:17611796};
CC Temperature dependence:
CC Optimum temperature is 37 degrees Celsius.
CC {ECO:0000269|PubMed:17611796};
CC -!- PATHWAY: Cofactor biosynthesis; thiamine diphosphate biosynthesis;
CC thiamine diphosphate from thiamine: step 1/1.
CC {ECO:0000269|PubMed:17611796}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol {ECO:0000269|PubMed:17611796}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=3;
CC Name=1;
CC IsoId=B9DGU7-1; Sequence=Displayed;
CC Name=2;
CC IsoId=B9DGU7-2; Sequence=VSP_053286;
CC Name=3;
CC IsoId=B9DGU7-3; Sequence=VSP_053285;
CC -!- TISSUE SPECIFICITY: Expressed in roots, leaves and flowers.
CC {ECO:0000269|PubMed:17611796}.
CC -!- DISRUPTION PHENOTYPE: No visible phenotype under normal growth
CC conditions (PubMed:17611796). Tpk1 and tpk2 double mutants exhibit a
CC seedling lethal phenotype (PubMed:17611796).
CC {ECO:0000269|PubMed:17611796}.
CC -!- SIMILARITY: Belongs to the thiamine pyrophosphokinase family.
CC {ECO:0000305}.
