	Wild type		Gal-NBP35
Compartment	Gal	Glc	Gal	Glc
Cytosol
Isopropyl malate isomerase	0.30 ± 0.01	0.31 ± 0.05	0.40 ± 0.09	<0.04
Alcohol dehydrogenase	1.8 ± 0.3	2.0 ± 0.3	1.6 ± 0.2	2.4 ± 0.6
Mitochondria
Aconitase	3.5 ± 0.9	3.2 ± 0.4	2.9 ± 0.5	3.7 ± 0.6
Succinate dehydrogenase	0.30 ± 0.03	0.20 ± 0.02	0.20 ± 0.01	0.30 ± 0.01
Malate dehydrogenase	2.0 ± 0.1	1.5 ± 0.1	1.6 ± 0.1	1.5 ± 0.1
Citrate synthase	2.8 ± 0.4	2.9 ± 0.3	3.1 ± 0.6	3.7 ± 0.5

Enzyme activities of cytosolic and mitochondrial proteins were determined using postmitochondrial supernatants and mitochondria, respectively, isolated from wild-type and Gal-NBP35 cells grown in minimal media containing galactose (Gal) or glucose (Glc). Activities are given in units per mg of protein.
