PRPP Biosynthesis

Veillonella atypica ACS-049-V-Sch6
The biosynthesis of phosphoribosyl pyrophosphate begins as a product of the pentose phosphate and D-ribose 5-phosphate interaction. When catalyzed with a phosphopentomutase, the product is a ribose 1-phosphate. Ribose 1-phosphate can interact spontaneously with ATP resulting in a release of hydrogen ion, ADP and a ribose 1,5-biphosphate. Ribose 1,5-biphosphate is then phosphorylated through a ribose 1,5-bisphosphokinase resulting in the release of ADP and phosphoribosyl pyrophosphate. Phosphoribosyl pyrophosphate will then participate in the purine nucleotides de novo biosynthesis pathway. Alternatively pentose phosphate and D-ribose 5-phosphate's interaction can be phosphorylated through an ATP driven ribose-phosphate diphosphokinase resulting in a release of a hydrogen ion, an AMP and a phosphoribosyl pyrophosphate which will again participate in the purine nucleotides de novo biosynthesis pathway.

Proxibarbal Drug Metabolism

Homo sapiens
Proxibarbal is a drug that is not metabolized by the human body as determined by current research and biotransformer analysis. Proxibarbal passes through the liver and is then excreted from the body mainly through the kidney.

Protein Synthesis: Valine

Rattus norvegicus
Protein synthesis is an essential life process that builds the important large amino acid macromolecules that function as enzymes, antibodies, and cellular structural components. Although synthesis begins with the transcription of DNA into RNA, this pathway depicts the reactions that occur during translation. Transcribed messenger RNA (mRNA), which contains the genetic code to direct protein synthesis, is transported out of the nucleus and becomes bound to ribosomes in the cytoplasm or endoplasmic reticulum. The amino acids required to assemble polypeptide chains are delivered to the ribosomes using transfer RNA (tRNA). Each tRNA molecule has both a binding site for a specific amino acid and a three-nucleotide sequence called the anticodon that forms three complementary base pairs with an mRNA codon. Charging or loading the appropriate amino acid onto its tRNA is carried out by an aminoacyl-tRNA synthetase (aaRS or ARS), also called tRNA-ligase. This enzyme catalyzes the esterification of an amino acid to one of all its compatible tRNAs to form an aminoacyl-tRNA. Each of the twenty amino acids has a corresponding aa-tRNA made by a specific aminoacyl-tRNA synthetase. Ribosomes match the anticodons of the charged tRNA molecules with successive codons of the mRNA. After a match is found, the ribosome transfers the amino acid from the matching tRNA onto the growing peptide chain via a reaction termed peptide condensation, and the tRNAs, no longer carrying amino acids, are released.
