  • sodium pyruvate
  • Sodium pyruvate is commonly added to cell culture media as an additional source of energy, but may also have protective effects against hydrogen peroxide. (wikipedia.org)
  • specific pyruvate
  • Three specific pyruvate cycles are generally considered, each named for the principal molecule exported from the mitochondrion: malate, citrate, and iso-citrate.Other variants may exist, such as dissipative or "futile" pyruvate cycles. (wikipedia.org)
  • carbon dioxide
  • Pyruvate decarboxylase is a homotetrameric enzyme (EC 4.1.1.1) that catalyses the decarboxylation of pyruvic acid to acetaldehyde and carbon dioxide in the cytoplasm of prokaryotes, and in the cytoplasm and mitochondria of eukaryotes. (wikipedia.org)
  • Pyruvate decarboxylase starts this process by converting pyruvate into acetaldehyde and carbon dioxide. (wikipedia.org)
  • In the second reaction, occurring in the CT domain of an adjacent monomer, carbon dioxide is transferred to the acceptor molecule, pyruvate, to form oxaloacetate. (wikipedia.org)
  • protein
  • Cloning and expression of maize-leaf pyruvate, Pi dikinase regulatory protein gene. (ebi.ac.uk)
  • Further analysis of maize C(4) pyruvate,orthophosphate dikinase phosphorylation by its bifunctional regulatory protein using selective substitutions of the regulatory Thr-456 and catalytic His-458 residues. (ebi.ac.uk)
  • The pyruvate, orthophosphate dikinase regulatory proteins of Arabidopsis possess a novel, unprecedented Ser/Thr protein kinase primary structure. (ebi.ac.uk)
  • dikinase
  • Regulation of C4 photosynthesis: identification of a catalytically important histidine residue and its role in the regulation of pyruvate,Pi dikinase. (ebi.ac.uk)
  • Sequence of the phosphothreonyl regulatory site peptide from inactive maize leaf pyruvate, orthophosphate dikinase. (ebi.ac.uk)
  • cofactor
  • After the cofactor TPP reacts with pyruvate, which undergoes decarboxylation, the acetyl portion becomes a hydroxyethyl derivative covalently attached to TPP. (wikidoc.org)
  • Pyruvate Carboxylase Symmetry Comparison Pyruvate carboxylase uses a covalently attached biotin cofactor which is used to catalyze the ATP- dependent carboxylation of pyruvate to oxaloacetate in two steps. (wikipedia.org)
  • reacts
  • The electrochemical sensor includes a working electrode, a reference electrode, and a reagent localized near the working electrode that selectively reacts with pyruvate. (google.ca)
  • The active sites are inside a cavity in the core of the enzyme where hydrogen bonding can occur and where the pyruvate reacts with TPP. (wikipedia.org)
  • allosteric
  • In yeast cells, the interaction of yeast pyruvate kinase (YPK) with PEP and its allosteric effector Fructose 1,6-bisphosphate (FBP,) was found to be enhanced by the presence of Mg2+. (wikipedia.org)
