Probing the Dimerization Interface of <i>Leishmania infantum</i> Trypanothione Reductase with Site‐Directed Mutagenesis and Short Peptides

Abstract

Binding at the interface: We tested the inhibitory activity of a set of peptide sequences derived from an α-helix of the dimeric trypanothione reductase from Leishmania infantum. Replacement of a glutamic acid residue with a lysine promoted monomer dissociation and enzyme inhibition.
