TABLE 1.

The number of H₂O₂ and Fe²⁺ molecules in the Msm and Mtb SCF and NCF cells.

	Msm	Msm	Mtb	Mtb
	Per SCF cell	Per NCF cell	SCF (in μmoles) (per ug protein)	NCF (in μmoles) (per ug protein)
H2O2 (intracellular)	4.25 ± 0.27 × 106	2.55 ± 0.048 × 106	2.75 ± 0.44 × 10–5	1.52 ± 0.38 × 10–5
H2O2 (extracellular)	1.79 ± 0.18 × 108	1.05 ± 0.27 × 108	ND	ND
Labile Fe2+	1.11 ± 0.13 × 107	0.36 ± 0.023 × 107	1.69 ± 0.55 × 10–5	5.50 ± 1.06 × 10–6
Total iron (in Fe2+ form)	1.25 ± 0.22 × 107	1.04 ± 0.17 × 107	ND	ND

The Msm and Mtb H₂O₂ values were calculated from the Figures 2P,Q, respectively. Similarly, the Msm and Mtb Fe²⁺ values were calculated from the Figures 4A,E, respectively. ND, not determined.
