The iron-sulfur cluster-free hydrogenase (Hmd) from methanogenic archaea harbors an iron-
containing cofactor of yet unknown structure. X-ray absorption spectroscopy of the active, as …

The iron− sulfur cluster-free hydrogenase (Hmd) from methanogenic archaea harbors an
iron-containing, light-sensitive cofactor of still unknown structure as prosthetic group. The …

The iron–sulphur cluster-free hydrogenase (Hmd, EC 1.12. 98.2) from methanogenic
archaea is a novel type of hydrogenase that tightly binds an iron-containing cofactor. The …

The iron− sulfur-cluster-free hydrogenase Hmd (H2-forming
methylenetetrahydromethanopterin dehydrogenase) from methanogenic archaea has …

The activation of molecular hydrogen is of interest both from a chemical and biological
viewpoint. The covalent bond of H2 is strong (436 kJ mol− 1). Its cleavage is catalyzed by …

We have used 57Fe nuclear resonance vibrational spectroscopy (NRVS) to study the iron
site in the iron− sulfur cluster-free hydrogenase Hmd from the methanogenic archaeon …

Hydrogenases (H 2 ases) are metalloproteins. The great majority of them contain iron-sulfur
clusters and two metal atoms at their active center, either a Ni and an Fe atom, the [NiFe]-H 2 …

Hydrogenases are enzymes that catalyze reversible reactions that have H2 as a substrate or
product. There are three classes of hydrogenases which appear not to be structurally and …

The recent elucidation of the structures of iron-only hydrogenases from the microorganisms
Clostridium pasteurianum and Desulfovibrio desulfuricans has revealed that the presumed …
