In this study, we investigated the mechanism of O2 tolerance of Klebsiella oxytoca HP1 H2-evolving hydrogenase 3 (KHyd3) by mutational analysis and three-dimensional structure modeling. Results revealed that certain surface amino acid residues of KHy

The class of [NiFe]-hydrogenases comprises oxygen-sensitive periplasmic (PH) and oxygen-tolerant membrane-bound (MBH) enzymes. For three PHs and four MBHs from six bacterial species, structural features of the nickel–iron active site of hydrogen tu

Evolution and diversification of Group 1 [NiFe] hydrogenases. Is there a phylogenetic marker for O2-tolerance?

Autor: Wolfgang Nitschke, Maria-Eirini Pandelia, Wolfgang Lubitz

Publikováno v: Biochimica et Biophysica Acta (BBA) - Bioenergetics. 1817:1565-1575

Group 1 hydrogenases are periplasmic enzymes and are thus strongly affected by the "outside world" the cell experiences. This exposure has brought about an extensive heterogeneity in their cofactors and redox partners. Whereas in their majority they
