Abstract

The suitability of synchrotron radiation circular dichroism spectroscopy (SRCD) for studying interactions between the tricyclic peptide inhibitor siamycin I and the intact FsrC membrane sensor kinase in detergent micelles has been established. In the present study, tertiary structural changes demonstrate that inhibitor binding occurs at a different, non-overlapping site to the native ligand, GBAP.
