Deoxyadenosine monophosphate (dAMP), also known as deoxyadenylic acid or deoxyadenylate in its conjugate acid and conjugate base forms, respectively, is a derivative of the common nucleotide AMP, or adenosine monophosphate, in which the -OH group on the 2' carbon on the nucleotide's pentose has been reduced to just a hydrogen atom (hence the "deoxy-" part of the name).
In enzymology, a deoxyadenosine kinase (EC 2.7.1.76) is an enzyme that catalyzes the chemical reaction ATP + deoxyadenosine ⇌ {\displaystyle \rightleftharpoons } ADP + dAMP Thus, the two substrates of this enzyme are ATP and deoxyadenosine , whereas its two products are ADP and dAMP .
Nucleosides are glycosylamines that can be thought of as nucleotides without a phosphate group.A nucleoside consists simply of a nucleobase (also termed a nitrogenous base) and a five-carbon sugar (ribose or 2'-deoxyribose) whereas a nucleotide is composed of a nucleobase, a five-carbon sugar, and one or more phosphate groups.
Adenosine is one of the four nucleoside building blocks of RNA (and its derivative deoxyadenosine is a building block of DNA), which are essential for all life on Earth. Its derivatives include the energy carriers adenosine mono-, di-, and triphosphate , also known as AMP/ADP/ATP.
Deoxyadenosine triphosphate (dATP) is a nucleotide used in cells for DNA synthesis (or replication), as a substrate of DNA polymerase. [ 1 ] Deoxyadenosine triphosphate is produced from DNA by the action of nuclease P1, adenylate kinase , and pyruvate kinase .
The Purine Nucleotide Cycle is a metabolic pathway in protein metabolism requiring the amino acids aspartate and glutamate. The cycle is used to regulate the levels of adenine nucleotides, in which ammonia and fumarate are generated. [2] AMP converts into IMP and the byproduct ammonia.
5'-deoxyadenosine deaminase (also known as "DadD") is an enzyme that catalyzes the conversion of 5′-deoxyadenosine to 5′-deoxyinosine. [1] [2] To a lesser extent, the enzyme also catalyzes the deamination of 5′-methylthioadenosine, S-adenosylhomocysteine, and adenosine. [1] The molecular mass of the DadD enzyme is approximately 230 kDa. [1]
