Abstract
[NiFe]-hydrogenases catalyze the reversible reaction H2 ⇄ 2H+ + 2e-. Their basic module consists of a large subunit, coordinating the NiFe(CO)(CN)2 center, and a small subunit that carries electron-transferring iron-sulfur clusters. Here, we report the in vitro assembly of fully functional [NiFe]-hydrogenase starting from the isolated large and small subunits. Activity assays complemented by spectroscopic measurements revealed a native-like hydrogenase. This approach was used to label exclusively the NiFe(CO)(CN)2 center with 57Fe, enabling a clear view of the catalytic site by means of nuclear resonance vibrational spectroscopy. This strategy paves the way for in-depth studies of [NiFe]-hydrogenase catalytic intermediates.

Abstract
A [NiFe] hydrogenase (H2 ase) is a proton-coupled electron transfer enzyme that catalyses reversible H2 oxidation; however, its fundamental proton transfer pathway remains unknown. Herein, we observed the protonation of Cys546-SH and Glu34-COOH near the Ni-Fe site with high-sensitivity infrared difference spectra by utilizing Ni-C-to-Ni-L and Ni-C-to-Ni-SIa photoconversions. Protonated Cys546-SH in the Ni-L state was verified by the observed SH stretching frequency (2505 cm-1 ), whereas Cys546 was deprotonated in the Ni-C and Ni-SIa states. Glu34-COOH was double H-bonded in the Ni-L state, as determined by the COOH stretching frequency (1700 cm-1 ), and single H-bonded in the Ni-C and Ni-SIa states. Additionally, a stretching mode of an ordered water molecule was observed in the Ni-L and Ni-C states. These results elucidate the organized proton transfer pathway during the catalytic reaction of a [NiFe] H2 ase, which is regulated by the H-bond network of Cys546, Glu34, and an ordered water molecule.

Abstract
A novel in situ IR spectroscopic approach is demonstrated for the characterization of hydrogenase during catalytic turnover. E. coli hydrogenase 1 (Hyd-1) is adsorbed on a high surface-area carbon electrode and subjected to the same electrochemical control and efficient supply of substrate as in protein film electrochemistry during spectral acquisition. The spectra reveal that the active site state known as Ni-L, observed in other NiFe hydrogenases only under illumination or at cryogenic temperatures, can be generated reversibly in the dark at ambient temperature under both turnover and non-turnover conditions. The observation that Ni-L is present at all potentials during turnover under H2 suggests that the final steps in the catalytic cycle of H2 oxidation by Hyd-1 involve sequential proton and electron transfer via Ni-L. A broadly applicable IR spectroscopic technique is presented for addressing electrode-adsorbed redox enzymes under fast catalytic turnover.
