Guardian and chaperone - comparative Cu(II) coordination properties of CopD-derived motifs and the Met-rich loop of CopC.
While copper transport into bacterial cells remains poorly understood, the molecular basis of copper transfer across the periplasm is still largely unresolved. In this study, we investigated Cu(II) binding to peptide fragments derived from the periplasmic chaperone CopC and the inner membrane transporter CopD. The CopD...
