[Effect of catechins and proanthocyanidins on the initial stage of protein biosynthesis]. / Vliianie katekhinov i proantotsianidinov na nachal'nyi étap biosinteza belka.

Catechins and proanthocyanidins have been studied for their effect on initial stage of the protein biosynthesis. It has been found that (+)-catechin in all concentrations studied does not influence the intensity of t-RNA aminoacylation by 14C-glycine and 14C-arginine. Proanthocyanidins, namely, dimers B-3, B-6 and trimer C2 in the concentration of 10(-3) M completely inhibit the initial stage of the protein biosynthesis.
