Abstract excerpt

We identify and characterize two matrix (m)-AAA proteases (AtFtsH3 and AtFtsH10) present in the mitochondria of Arabidopsis thaliana. AtFtsH3 is the predominant protease in leaves of wild type plants. Both proteases assemble with prohibitins (PHBs) into high molecular weight complexes (approximately 2 MDa), similarly to their yeast counterparts. A smaller PHB complex (approximately 1 MDa), without the m-AAA...
