Resumo
The stability of carnosine, pyrrolylcarnosine (PC) and salicylcarnosine (SC) to the action of leucine aminopeptidase, carboxypeptidases B and Y was evaluated. It was found that proteolysis of carnosine, PC and SC under the action of leucine aminopeptidase does not occur. Carboxypeptidases B and Y, as well as the enzyme system of blood plasma and plasma membranes of rat brain cells, degraded peptides containing β-alanyl, N-pyrrolyl, N-salicylic fragments to varying degrees. In all cases, histidine is formed. The formation of pyrrole or salicylic acid does not occur. It was found that carnosine, PC and SC showed high stability to the action of amino- and carboxypeptidases in in vitro experiments.
