The PRCC1 gene is found on the long arm of Chromosome 5.Decarboxylation: Decarboxylation is a chemical reaction that removes a carboxyl group and releases carbon dioxide (CO2). Usually, decarboxylation refers to a reaction of carboxylic acids, removing a carbon atom from a carbon chain.Burst kinetics: Burst kinetics is a form of enzyme kinetics that refers to an initial high velocity of enzymatic turnover when adding enzyme to substrate. This initial period of high velocity product formation is referred to as the "Burst Phase".Tyrosine ammonia-lyase: Tyrosine ammonia lyase (L-tyrosine ammonia-lyase, TAL or Tyrase) is an enzyme in the natural phenols biosynthesis pathway. It transforms L-tyrosine into p-coumaric acid.Ammonia transporterProteinogenic amino acid: Proteinogenic amino acids are amino acids that are precursors to proteins, and are incorporated into proteins cotranslationally — that is, during translation. There are 23 proteinogenic amino acids in prokaryotes (including N-Formylmethionine, mainly used to initiate protein synthesis and often removed afterward), but only 21 are encoded by the nuclear genes of eukaryotes.MitoguazoneCadaverineLiver sinusoid: A liver sinusoid is a type of sinusoidal blood vessel (with fenestrated, discontinuous endothelium) that serves as a location for the oxygen-rich blood from the hepatic artery and the nutrient-rich blood from the portal vein.SIU SOM Histology GILysinuric protein intoleranceOrotic acidColes PhillipsGlutamineCyclohexylamineMature messenger RNA: Mature messenger RNA, often abbreviated as mature mRNA is a eukaryotic RNA transcript that has been spliced and processed and is ready for translation in the course of protein synthesis. Unlike the eukaryotic RNA immediately after transcription known as precursor messenger RNA, it consists exclusively of exons, with all introns removed.Ligase: In biochemistry, ligase (from the Latin verb ligāre — "to bind" or "to glue together") is an enzyme that can catalyze the joining of two large molecules by forming a new chemical bond, usually with accompanying hydrolysis of a small pendant chemical group on one of the larger molecules or the enzyme catalyzing the linking together of two compounds, e.g.AcetyllysineCycloheximideUreohydrolaseAcetyltransferaseMalonyl-S-ACP:biotin-protein carboxyltransferase: Malonyl-S-ACP:biotin-protein carboxyltransferase (, malonyl-S-acyl-carrier protein:biotin-protein carboxyltransferase, MadC/MadD, MadC,D, malonyl-[acyl-carrier protein]:biotinyl-[protein] carboxyltransferase) is an enzyme with system name malonyl-(acyl-carrier protein):biotinyl-(protein) carboxytransferase.
