1.12.99.6 O2 reacts with the enzyme, reversibly, causing inactivation. Although traces of O2 (less than 1%) rapidly and completely remove H2 oxidation activity, the enzyme sustains partial activity for H2 production even in the presence of 1% O2 in the atmosphere. O2 tolerance of the [NiFeSe]-hydrogenase is greater at higher temperature Desulfomicrobium baculatum
