Abstract

The aim of this work is to combine mutagenesis, stopped-flow methodology and spectroscopy to provide a full kinetic characterisation of protochlorophyllide reductase (POR), which catalyses the light-dependent step in chlorophyll biosynthesis. This is the first time that large quantities of this fascinating enzyme have become available for detailed enzymological studies. The specific objectives are to examine: 1) binding of NADPH and its role in controlling the aggregation state of POR; 2) the binding of Pchlide to this enzyme, and to search for enzyme-bound intermediates of Pchlide reduction, and 3) to initiate structural studies on this enzyme using a combination of site- directed mutagenesis, X-ray crystallography, and NMR.
