In enzymology, a thiamine diphosphokinase (EC 2.7.6.2) is an enzyme that catalyzes the chemical reaction ATP + thiamine ⇌ {\displaystyle \rightleftharpoons } AMP + thiamine diphosphate Thus, the two substrates of this enzyme are ATP and thiamine , whereas its two products are AMP and thiamine diphosphate .
Thiamine pyrophosphate (TPP or ThPP), or thiamine diphosphate (ThDP), or cocarboxylase [1] is a thiamine (vitamin B 1) derivative which is produced by the enzyme thiamine diphosphokinase. Thiamine pyrophosphate is a cofactor that is present in all living systems, in which it catalyzes several biochemical reactions.
In enzymology, a thiamine-diphosphate kinase is an enzyme involved in thiamine metabolism. It catalyzes the chemical reaction. thiamine diphosphate + ATP thiamine triphosphate + ADP. Thus, the two substrates of this enzyme are ATP and thiamine diphosphate, whereas its two products are ADP and thiamine triphosphate.
Thiamine, also known as thiamin and vitamin B 1, is a vitamin – an essential micronutrient for humans and animals. [1] [3] [4] It is found in food and commercially synthesized to be a dietary supplement or medication. [1] Phosphorylated forms of thiamine are required for some metabolic reactions, including the breakdown of glucose and amino ...
In enzymology, a thiamine-phosphate kinase (EC 2.7.4.16) is an enzyme that catalyzes the chemical reaction ATP + thiamine phosphate ⇌ {\displaystyle \rightleftharpoons } ADP + thiamine diphosphate Thus, the two substrates of this enzyme are ATP and thiamine phosphate , whereas its two products are ADP and thiamine diphosphate .
In enzymology, a thiamine-phosphate diphosphorylase ( or, thiamine-phosphate pyrophosphorylase ) (EC 2.5.1.3) is an enzyme that catalyzes the chemical reaction 4-Amino-5-hydroxymethyl-2-methylpyrimidine diphosphate + 4-methyl-5-(2-phosphono-oxyethyl)thiazole ⇌ {\displaystyle \rightleftharpoons } diphosphate + thiamine monophosphate
In enzymology, a thiamine kinase (EC 2.7.1.89) is an enzyme that catalyzes the chemical reaction ATP + thiamine ⇌ {\displaystyle \rightleftharpoons } ADP + thiamine phosphate Thus, the two substrates of this enzyme are ATP and thiamine , whereas its two products are ADP and thiamine phosphate .
Above is a ball-and-stick model of the inorganic phosphate molecule (H PO 4 2−).Colour coding: P (orange); O (red); H (white). The chemical activity of a protein kinase involves removing a phosphate group from ATP and covalently attaching it to one of three amino acids that have a free hydroxyl group.
