Antioxidant Functions of Nitric Oxide Synthase in a Methicillin Sensitive Staphylococcus aureus

Table 2

Nitric oxide synthase activity in different S. aureus strains.

Strain	NOS activity (%)*
SH1000	3.95±1.61
SH1000ΔSaNOS	0
Complemented strain	26.47±3.95

∗%Citrulline formed in relation to total L-arginine used in the assay. Citrulline conversion in the mutant strain was below the background level (control reaction with no protein extract). Values represent average of three independent experiments ± standard deviation.
