Ascorbate, dithiothreitol and TCEP reduce copper(II) to copper(I), and the donor set that stabilizes the divalent ion does not stabilize the monovalent one, so the complex is destroyed and the released copper becomes redox-active
Kinetic analysis of Arabidopsis GCL showed that the enzyme was inactivated by buthionine sulfoximine, a potent inhibitor of mammalian GCL, and used a random ter-reactant kinetic mechanism with a preferred order of binding for catalysis (Jez et al., 2004)

Record-keeping requirements extend beyond basic research notes
Understanding GHK-Cus mechanism of action requires a brief look at its interaction with copper an essential trace mineral involved in over 50 enzymatic processes in the human body
This copper-based peptide has demonstrated regenerative effects across skin and hair applications, particularly for stimulating follicles, increasing hair density, and supporting wound repair
