Phosphate oxygens 是什么
WebJul 20, 2024 · Carboxylate oxygens can also accept phosphate groups from ATP. This typically happens in two different ways. First, the carboxylate can attack the g-phosphate of ATP to accept phosphate, generates a species known as an 'acyl phosphate'. An example is the first part of the reaction catalyzed by glutamine synthase (EC 6.3.1.2): WebThe phosphorus atom of the phosphodiester moiety, linking the adjacent nucleosides of the DNA's sugar-phosphate backbone, is at the centre of a tetrahedron configuration of four oxygen atoms. Esterification, by adduct formation, of one of the two non-carbon-bonded oxygens forms the phosphotriester configuration ( Figure 1a ) resulting in the ...
