Figure 3. O2-inactivation of lyophilized [FeFe]-hydrogenases by increasing humidity.

Figure 3

Lyophilized HYDA1 (a) and CPI (b) proteins in their [4FeH] or [6FeH] maturation states were exposed for 30 min to the indicated levels of humidity in pure O2 gas prior to specific activity determination. Values represent the mean of 3 independent measurements, error bars give standard deviations.
