Figure 1From: Antagonizing Methuselah to extend life spanThe location of RWR peptide binding to the Mth ectodomain. The Mth ectodomain structure [13] was visualized with PyMOL (PyMOL Molecular Graphics System). The tryptophan (W) residue previously thought to be positioned at the ligand-binding site is indicated in green, and the region near the carboxyl terminus to which the RWR peptide was located by Ja et al. [2] is indicated by an orange circle.Back to article page
