A semisynthetic peptide-metalloporphyrin responsive matrix for artificial photosynthesis

This thesis is concerned with the constitution of chiral responsive matrix assemblies that may undergo light-driven conformational changes and self-select vibrations to develop vibronic states for driving semi-classical coherent transfer with nearly 100% yield in a lossless NCAP process.

This thesis is concerned with the constitution of chiral responsive matrix assemblies that may undergo light-driven conformational changes and self-select vibrations to develop vibronic states for driving semi-classical coherent transfer with nearly 100% yield in a lossless NCAP process. In this work, a truncated CsmA derived from the CsmA protein from the baseplate of the Chlorobaculum tepidum has been used to engineer a chiral matrix around a zinc protoporphyrin IX (ZnPP) chromophore (Chapter 2). After the study of the specific structure of tCsmA-ZnPP complex, the mechanism of self-assembly was resolved (Chapter 3 and Chapter 4). Expression and purification of tCsmA in E.coli was explored to pave the way for other methods, such as NMR (Chapter 5).
