Abstract
The first NMR structure of a Cu(I)-bound metallochaperone model with the conserved sequence MT/HCXXC revealed that at pH ~3.0 and ~6.8 Cu(I) binds through one Cys and the Met rather than the two Cys residues, differently than at pH ~8.5. This suggests a possible role of Met in metal transport.
