Nucleic acid other biological data made available through the NCBI web site. Deoxyribonucleic acid (DNA) is a nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms. The DNA segments carrying this genetic information are called genes. Likewise, other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information. Along with RNA and proteins, DNA is one of the three major macromolecules that are essential for all known forms of life. DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate
Chorismic acid and pyruvate. This enzyme catalyses the first step in ubiquinone biosynthesis in "Escherichia coli" and other Gram-negative bacteria. Chorismic acid Chorismic acid, more commonly known as its anionic form chorismate, is an important biochemical intermediate in plants and microorganisms. It is a precursor for: The name chorismic acid derives from a classical Greek word, "χωρίζω" meaning "to separate", because the compound plays a role as a branch-point in aromatic amino acid biosynthesis. Shikimate → shikimate-3-phosphate → 5-enolpyruvylshikimate-3-phosphate (5-O-(1-carboxyvinyl)-3-phosphoshikimate) Chorismate synthase is an enzyme that catalyzes the final chemical reaction 5-O-(1-carboxyvinyl)-3-phosphoshikimate → chorismate + phosphate. Chorismate is transformed into "para"-aminobenzoic acid
