Research Interests

Webber's research interests have focused on the molecular mechanisms of photosynthetic energy transduction and chloroplast development. A long-standing project has focused on the structure and function of the photosystem I reaction center complex. The structure of photosystem I is now known at atomic resolution. However, it is still unknown why the electron transfer cofactors have such a remarkably low potential.

His research uses recombinant DNA techniques to specifically alter the genes encoding the photosystem I heterodimer to understand how the protein environment may modulate essential physico-chemical properties of the electron transfer intermediates. The eukaryotic green alga Chlamydomonas reinhardtii is used as a model organism in these studies. The chloroplast genome of Chlamydomonas can be easily transformed using a "gene gun" to shoot modified genes, carried on sub-micron sized gold particles, into the chloroplast. Mutant cells are produced that synthesize the reaction-center complex with altered polypeptide components. These site-specific mutants of Chlamydomonas are characterized using a range of molecular, biochemical and biophysical techniques.
