  2. Transketolase - Wikipedia

    en.wikipedia.org/wiki/Transketolase

    Transketolase (abbreviated as TK) is an enzyme that, in humans, is encoded by the TKT gene. [1] It participates in both the pentose phosphate pathway in all organisms and the Calvin cycle of photosynthesis. Transketolase catalyzes two important reactions, which operate in opposite directions in these two pathways.

  3. TKTL1 - Wikipedia

    en.wikipedia.org/wiki/TKTL1

    Transketolase-like-1 (TKTL1) is a gene closely related to the transketolase gene (TKT). It emerged in mammals during the course of evolution and, according to the latest research findings, is considered one of the key genes that distinguishes modern humans ( Homo sapiens ) from Neanderthals .

  4. Enzyme - Wikipedia

    en.wikipedia.org/wiki/Enzyme

    Enzymes (/ ˈ ɛ n z aɪ m z /) are proteins that act as biological catalysts by accelerating chemical reactions.The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.

  5. Thiamine pyrophosphate - Wikipedia

    en.wikipedia.org/wiki/Thiamine_pyrophosphate

    In what is essentially the reverse of step two, the electrons push back in the opposite direction forming a new bond between the substrate carbon and another atom. (In the case of the decarboxylases, this creates a new carbon-hydrogen bond. In the case of transketolase, this attacks a new substrate molecule to form a new carbon-carbon bond.)

  6. Transferase - Wikipedia

    transketolase and transaldolase: aldehyde or ketone groups EC 2.3: acyltransferase: acyl groups or groups that become alkyl groups during transfer EC 2.4: glycosyltransferase, hexosyltransferase, and pentosyltransferase: glycosyl groups, as well as hexoses and pentoses: EC 2.5: riboflavin synthase and chlorophyll synthase: alkyl or aryl groups ...

  7. Pentose phosphate pathway - Wikipedia

    en.wikipedia.org/wiki/Pentose_phosphate_pathway

    The pentose phosphate pathway. The pentose phosphate pathway (also called the phosphogluconate pathway and the hexose monophosphate shunt or HMP shunt) is a metabolic pathway parallel to glycolysis. [1]

    The problem, according to co-owner Paul Allen, was Traf-O-Data’s business model and the fact that neither Gates, Allen nor Gilbert did any research on how to grow such a business.

  9. Formaldehyde transketolase - Wikipedia

    en.wikipedia.org/wiki/Formaldehyde_transketolase

    In enzymology, a formaldehyde transketolase (EC 2.2.1.3) is an enzyme that catalyzes the chemical reaction D-xylulose 5-phosphate + formaldehyde ⇌ {\displaystyle \rightleftharpoons } glyceraldehyde 3-phosphate + glycerone
