CC -!- FUNCTION: Component of the cytosolic iron-sulfur (Fe-S) protein
CC assembly (CIA) machinery. Required for the maturation of
CC extramitochondrial Fe-S proteins. Part of an electron transfer chain
CC functioning in an early step of cytosolic Fe-S biogenesis, facilitating
CC the de novo assembly of a [4Fe-4S] cluster on the cytosolic Fe-S
CC scaffold complex. Electrons are transferred from NADPH via a FAD- and
CC FMN-containing diflavin oxidoreductase. Together with the diflavin
CC oxidoreductase, also required for the assembly of the diferric tyrosyl
CC radical cofactor of ribonucleotide reductase (RNR), probably by
CC providing electrons for reduction during radical cofactor maturation in
CC the catalytic small subunit. {ECO:0000255|HAMAP-Rule:MF_03115}.
CC -!- COFACTOR:
CC Name=[2Fe-2S] cluster; Xref=ChEBI:CHEBI:190135;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_03115};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_03115};
CC -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_03115}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03115}.
CC Mitochondrion intermembrane space {ECO:0000255|HAMAP-Rule:MF_03115}.
CC -!- DOMAIN: The C-terminal domain binds 2 Fe-S clusters but is otherwise
CC mostly in an intrinsically disordered conformation. {ECO:0000255|HAMAP-
CC Rule:MF_03115}.
CC -!- DOMAIN: The N-terminal domain has structural similarity with S-
CC adenosyl-L-methionine-dependent methyltransferases, but does not bind
CC S-adenosyl-L-methionine. It is required for correct assembly of the 2
CC Fe-S clusters. {ECO:0000255|HAMAP-Rule:MF_03115}.
CC -!- DOMAIN: The twin Cx2C motifs are involved in the recognition by the
CC mitochondrial MIA40-ERV1 disulfide relay system. The formation of 2
CC disulfide bonds in the Cx2C motifs through dithiol/disulfide exchange
CC reactions effectively traps the protein in the mitochondrial
CC intermembrane space. {ECO:0000255|HAMAP-Rule:MF_03115}.
CC -!- SIMILARITY: Belongs to the anamorsin family. {ECO:0000255|HAMAP-
CC Rule:MF_03115}.
