ghk-cu copper coordination sites a) Domain schematic for the production of GHK-tagged protein. (b) RCSB PDB - 6QUG: GHK

RCSB PDB 6QUG: GHK tagged MBP Nup98(1 29) GHK Cu (glycyl L histidyl L lysine copper complex) is a naturally occurring tripeptide bound to a copper ion. It is formed by the coordination of the peptide GHK with copper (Cu) and has been identified in Aesthetics Infinity Medical Institute A peptide can change character when it holds a metal ion. GHK Cu is a coordination complex: the Gly His Lys tripeptide provides nitrogen rich binding sites, especially around the N terminus and histidine imidazole. In laboratory
