Phosphoamide bond
Webphosphoamide bond is highly unstable to acid, we digested [32P]phosphoryl-peptide with alkali to obtain [32P]phospho-amino acid. The [32P]phosphoryl-peptide was hydrolyzed with 3 N KOHat 100°C for various times, and the hydrolysates were electrophoresed on DEAE-cellulose paper. As shown in Figure 4A, three radioactive spots were observed at an ... Web1. Derivatives of uridylyl-(5′ → N)-phenylalanine were obtained, methylated on the ring nitrogen N 3 and the phosphoric acid radical.. 2. In studies of acid, alkaline, and enzyme hydrolysis of these compounds, it was established that CH 3-groups in position 3 of uracil do not exert a significant influence on reactivity of the phosphoamide bond in uridylyl-(5′ → …
