The SAM complex of plants. A) Schematic representation of the SAM complexes found in yeast and plants. B) Table indicating the presence or absence of a component of the SAM complexes found in plants. C) Representation of the different domains of yeast Sam37, Human Metaxin and Arabidopsis metaxin proteins. All three share similar Glutathione S-transferase (GST) domains. However the location of the transmembrane domains (TM) differs. A motif analysis search of plant metaxin sequences identified Motif 1 to regions between amino acids 37 and 79 and motif 2 between amino acids 104 and 155 in Arabidopsis. These motifs appear only in plant like Metaxins and near a region required for protein binding. Colors and abbreviations are the same as Figure 2.
