Webenzyme linkage is a phosphoamide bond between the cata-lytic lysine and GMP (10, 12-14, 21, 22), suggesting that the nucleotidyl transfer mechanism proceeds via nucleophilic attack of the E-amino group of the lysine on the a phosphate of GTP (23). The extensive conservation of the capping reaction suggests that the GMP-lysine bond is a feature ... Webphos·pho·ar·gi·nine. ( fos'fō-ar'ji-nēn ), A compound (in particular, a phosphagen) of l-arginine with phosphoric acid containing the phosphoamide bond; a source of energy in the contraction of muscle in invertebrates, corresponding to phosphocreatine in the muscles of vertebrates. Compare: phosphocreatine. Synonym (s): arginine phosphate. WebBased on the type of chemical bond formed with the phosphate group, amino acids can be divided into several groups. The first type of bond is a simple phosphoamide bond, when the phosphate group is attached to the hydroxyl residue of an amino acid (Ser, Thr, and Tyr); this type of bond is extremely stable chemically, and is resistant to both acids high spin golf balls for seniors

"Phosphoramidates (sometimes also called amidophosphates) are a class of phosphorus compounds structurally related to phosphates (or organophosphates) via the substitution of an OR for a NR2. They are derivatives of phosphoramidic acids O=P(OH)(NR2)2, O=P(OH)2(NR2). A phosphorodiamidate (or diamidophosphate) is a phosphate that has two of its OH groups substituted by NR2 groups to give a species with the general formula O=P(OH)(NH2)2. The subs… " - Phosphoamide bond
