[Participation of phosphopeptides in oxidative amino acid exchange in brain tissue].
Specific proteins and phosphopeptides of nervous tissue soluble in acidified organic solvents have been shown to have an active participation in the metabolism of ammonia. Nitrogen phosphopeptides (amides) bound to phosphate residues which are non stable in acids. It was shown that acid-labil nitrogen (amide group) of phosphopeptides, bound to phosphate risidue, participates in the metabolism of ammonia formed during the oxidative deamination of amino acids. The data obtained indicate that 3'--5'-AMP dependent proteinkinase participates in the phosphorilation of phosphopeptides.
