Proteomics of the chloroplast: experimentation and prediction

Abstract

New technologies, in combination with increasing amounts of plant genome sequence data, have opened up incredible experimental possibilities to identify the total set of chloroplast proteins (the chloroplast proteome) as well as their expression levels and post-translational modifications in a global manner. This is summarized under the term 'proteomics' and typically involves two-dimensional electrophoresis or chromatography, mass spectrometry and bioinformatics. Complemented with nucleotide-based global techniques, proteomics is expected to provide many new insights into chloroplast biogenesis, adaptation and function.
