Characterization of a novel translational inhibitor from Leishmania mexicana promastigotes.

An inhibitory activity blocking protein synthesis elongation in several eukaryotic systems has been detected in Leishmania mexicana extracts. This factor, which competes with aminoacylation of tRNA and also affects the subsequent polymerization step, is a strong inhibitor of polypeptide synthesis in...
