[Mechanisms of formation and biological role of protein carbamates]

Experimental data are presented evidencing for the fact that tissue proteins under conditions in vivo are subjected to enzymic carboxylation with formation of carbaminic groups. In this case a charge variation in definite sites of protein molecule is observed, which specifies variation of the protein conformation and biological properties. Basic regularities of protein carbamate formation reactions are revealed with factors affecting their intensity enumerated. The reactions are shown to be of great biological significance for the respiration processes, realization of hormonal effects of peptide and protein hormones as well as for regulation of tissue homeostasis under conditions of acidic-alkaline state variation in the organism.
