Figure 4From: A glutathione-based system for defense against carbonyl stress in Haemophilus influenzaeInduction of AdhC activity by formaldehyde. The activity of AdhC (as a measure of the change in NADH consumed per minute per mg total protein as described in the Materials and methods) was determined at time points in cells grown in BHI media alone (black bars) and then in media with 0.3% formaldehyde added at 3 h (light grey bars) and with 1 mM GSNO added (dark grey bars).Back to article page
