Down the Iron Path: Mitochondrial Iron Homeostasis and Beyond

open access: yesCells, 2021
Cellular iron homeostasis and mitochondrial iron homeostasis are interdependent. Mitochondria must import iron to form iron–sulfur clusters and heme, and to incorporate these cofactors along with iron ions into mitochondrial proteins that support ...

Crystallographic snapshots of sulfur insertion by lipoyl synthase [PDF]

open access: yes, 2018
Lipoyl synthase (LipA) catalyzes the insertion of two sulfur atoms at the unactivated C6 and C8 positions of a protein-bound octanoyl chain to produce the lipoyl cofactor. To activate its substrate for sulfur insertion, LipA uses a [4Fe-4S] cluster and S-

Cluster and fold stability of E. coli ISC-type ferredoxin.

open access: yesPLoS ONE, 2013
Iron-sulfur clusters are essential protein prosthetic groups that provide their redox potential to several different metabolic pathways. Formation of iron-sulfur clusters is assisted by a specialised machine that comprises, among other proteins, a ...

Mechanism of Iron–Sulfur Cluster Assembly: In the Intimacy of Iron and Sulfur Encounter

open access: yesInorganics, 2020
Iron–sulfur (Fe–S) clusters are protein cofactors of a multitude of enzymes performing essential biological functions. Specialized multi-protein machineries present in all types of organisms support their biosynthesis.

Structural Basis of RICs Iron Donation for Iron-Sulfur Cluster Biogenesis

open access: yesFrontiers in Microbiology, 2021
Escherichia coli YtfE is a di-iron protein of the widespread Repair of Iron Centers proteins (RIC) family that has the capacity to donate iron, which is a crucial component of the biogenesis of the ubiquitous family of iron-sulfur proteins.

TtcA a new tRNA-thioltransferase with an Fe-S cluster [PDF]

open access: yes, 2014
International audienceTtcA catalyzes the post-transcriptional thiolation of cytosine 32 in some tRNAs. The enzyme from Es-cherichia coli was homologously overexpressed in E. coli.
