The 510-methenyltetrahydromethanopterin hydrogenase (or Hmd) the so-called iron-sulfur cluster-free hydrogenase is an enzyme found in methanogenic archea such as Methanothermobacter marburgensis. It was discovered and first characterized by the Thauer group at the Max Planck Institute in Marburg. Hydrogenases are enzymes that either reduce protons or oxidize molecular dihydrogen.
