Figure 1From: Dual organism design cycle reveals small subunit substitutions that improve [NiFe] hydrogenase hydrogen evolutionStructural model of the A. macleodii [NiFe] uptake hydrogenase small subunit HynS, highlighting the three Fe-S clusters, and residues His230 and Pro285, which were targeted for substitution to cysteine residues. For reference, the location of the active site is shown, but the rest of the large subunit structure was omitted to simplify viewing of the small subunit. The structural model was generated by Phyre using structure PDB: 1h2a as a model [27, 28].Back to article page
