Specific enzyme activities of NOX and catalase in recombinant M. neoaurum strains.

Strains	Enzyme Activity *
	NOX (mU/mg)	Catalase (U/mg)
JC-12p261	25.6 ± 1.5	27 ± 3
JC-12yodC	337.2 ± 9.6	23 ± 5
JC-12yodC-katA	312.3 ± 6.3	235 ± 6

Note: The results are shown in biological triplicate. * One unit of NOX enzyme activity is defined as the amount of enzyme that produced 1 μmol of NAD⁺ per minute at 30 °C and pH 7.0. One unit of catalase enzyme activity is defined as the decomposition of 1 µmol H₂O₂ (ε₂₄₀ = 43.6 × 10³/cm/M) per min at 30 °C and pH 7.0.
