Structure, function, and formation of biological iron-sulfur clusters

Johnson, Deborah C., Dean, Dennis R., Smith, Archer D., Johnson, Michael K.·2005·Annual Review of Biochemistry

Abstract

Iron-sulfur [Fe-S] clusters are ubiquitous and evolutionary ancient prosthetic groups that are required to sustain fundamental life processes. Owing to their remarkable structural plasticity and versatile chemical/electronic features [Fe-S] clusters participate in electron transfer, substrate binding/activation, iron/sulfur storage, regulation of gene expression, and enzyme activity. Formation of intracellular [Fe-S] clusters does not occur spontaneously but requires a complex biosynthetic machinery. Three different types of [Fe-S] cluster biosynthetic systems have been discovered, and all of them are mechanistically unified by the requirement for a cysteine desulfurase and the participation of an [Fe-S] cluster scaffolding protein. Important mechanistic questions related to [Fe-S] cluster biosynthesis involve the molecular details of how [Fe-S] clusters are assembled on scaffold proteins, how [Fe-S] clusters are transferred from scaffolds to target proteins, how various accessory proteins participate in [Fe-S] protein maturation, and how the biosynthetic process is regulated.

  • Fe-S clusters are ubiquitous inorganic co-factors that contribute to genome integrity, gene regulation, energy production, and immune responses, and are required for numerous biological functions, particularly enzymatic activity.

    “Fe-S clusters are ubiquitous, inorganic co-factors that contribute to a wide range of cellular pathways from genome integrity and gene regulation to energy production and immune responses, and are required for numerous biological functions, particularly enzymatic activity (Beinert, 2000; Johnson et al., 2005; Lee et al., 2009; Fuss et al., 2015).”

  • Iron acts alone or in iron-sulfur clusters as a prosthetic moiety for oxidoreductase, nitrogenase, hydrogenase, dehydrogenase, and hydratase enzyme families.

    “iron can act alone or in iron–sulfur clusters as a prosthetic moiety for members of the oxidoreductase, nitrogenase, hydrogenase, dehydrogenase, and hydratase enzyme families [7–12].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
