1CC1 - PubMed Abstract: 
[NiFeSe] hydrogenases are metalloenzymes that catalyze the reaction H2<-->2H+ + 2e-. They are generally heterodimeric, contain three iron-sulfur clusters in their small subunit and a nickel-iron-containing active site in their large subunit that includes a selenocysteine (SeCys) ligand.
