The Arabidopsis mitochondrial proteome project (1996-2004)

More recent data can be found at gelmap.de

An Arabidopsis thaliana mitochondrial proteome project was started for a comprehensive investigation of mitochondrial functions in plants. As a first step the proteome of mitochondria isolated from suspension cell cultures was characterized by high resolution 2D gel electrophoresis and mass spectrometry. Currently the proteomes of selected Arabidopsis knock-out mutants concerning nuclear genes of mitochondrial proteins are under investigation in our laboratory.

List of identified proteins

(last update: Feb. 2003)

The Numbers refer to the protein spots of a 2D gel of the mitochondrial proteome from Arabidopsis. The accession numbers are linked to the corresponding database entries of TAIR. Proteins were identified by Edman Degradation (ED), Immunostaining (IgG), Matrix-assisted Laser Desorption Ionisation / Time of Flight Mass Spectrometry (MALDI) or Electrospray Ionization Tandem Mass Spectrometry (ESI). Sequences determined refer to N-terminal sequences (N) or internal peptide sequences (I).
