Protease addition	DMSO reductase activity		Fumarate reductase activity
	−	+	−	+
MR-1 cells	1.21 ± 0.11	1.24 ± 0.02	9.29 ± 0.58	7.69 ± 1.85
MR-1 lysate	1.00 ± 0.18	1.06 ± 0.17	17.9 ± 0.47	10.5 ± 2.02
E. coli lysate	0.46 ± 0.02	0.35 ± 0.00	3.16 ± 0.08	0.22 ± 0.03

Reductase activity reported as ΔA₆₀₀ per min per OD₆₀₀. Average values and standard deviations were generated from at least duplicate samples. MG1655 was the strain of E. coli used.
