Estimated and deduced molecular mass values of mtPDC catalytic subunits

Molecular Mass

Subunit	Maize	Pea	Arabidopsis	Pea	Potato
	kD
E1α	43	43a	43.0b	43.5c	43.2d
E1β	40	38a	39.2e	38.7c	n.a.
E2	52 –53	76a	60.0f	n.a.	n.a.
E3	62 –63	57a,60g,h	n.a.i	50.4h	n.a.

Values are based on SDS-PAGE analysis of isolated mitochondria and therefore represent processed proteins. Molecular mass values deduced from sequenced cDNA clones represent precursor proteins (i.e. targeting peptide plus mature protein).
