Oliveira, Jan Skov Pedersen, Jan-André Gertenbach, Mark Young, and Trevor Douglas* Protein Cage Nanoparticles as Secondary Building Units for the Synthesis of 3- Dimensional Coordination Polymers Supporting Information Figure S1. (A) Ribbon diagram representation of Dps. Inset indicates the position of Cys101, which remains addressable by sulfydryl-directed compounds in the C126S mutant. Dynamic light scattering profiles of (B) unmodified and (C) phenanthrolene-labeled C126S indicate that diameters of both constructs are in relatively unchanged compared to native, unmodified cage.
