ABSTRACTIron (Fe) and sulfur (S) are required elements for life, and changes in their availability can limit the ecological distribution and function of microorganisms. In anoxic environments, soluble Fe typically exists as ferrous iron [Fe(II)] and

The [FeFe]-hydrogenase H-cluster is a complex organometallic cofactor whose assembly and installation requires three dedicated accessory proteins referred to as HydE, HydF, and HydG. The roles of these maturases and the precise mechanisms by which th

Iron sulfur (Fe-S) proteins are essential and ubiquitous across all domains of life, yet the mechanisms underpinning assimilation of iron (Fe) and sulfur (S) and biogenesis of Fe-S clusters are poorly understood. This is particularly true for anaerob

Radical S-adenosyl-l-methionine (SAM) enzymes initiate biological radical reactions with the 5’-deoxyadenosyl radical (5’-dAdo•). A [4Fe-4S](+) cluster reductively cleaves SAM to form the Ω organometallic intermediate in which the 5’-deoxyad

The organometallic H-cluster of the [FeFe]-hydrogenase consists of a [4Fe-4S] cubane bridged via a cysteinyl thiolate to a 2Fe subcluster ([2Fe]H) containing CO, CN-, and dithiomethylamine (DTMA) ligands. The H-cluster is synthesized by three dedicat

Maturation of [FeFe]-hydrogenase (HydA) involves synthesis of a CO, CN(−), and dithiomethylamine (DTMA)-coordinated 2Fe subcluster that is inserted into HydA to make the active hydrogenase. This process requires three maturation enzymes: the radica

Catalysis by canonical radical S-adenosyl-l-methionine (SAM) enzymes involves electron transfer (ET) from [4Fe-4S]+ to SAM, generating an R3S0 radical that undergoes regioselective homolytic reductive cleavage of the S-C5' bond to generate the 5'-dAd

Methanogens have a high demand for iron (Fe) and sulfur (S); however, little is known of how they acquire, deploy, and store these elements and how this, in turn, affects their physiology. Methanogens were recently shown to reduce pyrite (FeS2), gene
