What's a GeneRIF?

results show that Nfs1 adopts a higher oligomeric state in the Isd11-bound form compared to that in the free form
Title: The effect of the adaptor protein Isd11 on the quaternary structure of the eukaryotic cysteine desulphurase Nfs1.
Whereas Nfs1p by itself was inactive, the Nfs1p.Isd11p complex formed persulfide and was active as a cysteine desulfurase. In the absence of Isd11p, Nfs1p was able to bind the substrate cysteine but failed to form a persulfide.
Title: Persulfide formation on mitochondrial cysteine desulfurase: enzyme activation by a eukaryote-specific interacting protein and Fe-S cluster synthesis.
Isd11 acts together with Nfs1 in an early step in the biogenesis of Fe/S proteins.
Title: The Nfs1 interacting protein Isd11 has an essential role in Fe/S cluster biogenesis in mitochondria.
Isd11 is an indispensable eukaryotic component of the mitochondrial machinery for biogenesis of Fe/S proteins.

Preferred Names: Isd11p

NP_010968.1

Cysteine desulfurase (Nfs1p) activator; essential for the formation of the persulfide intermediate at the desulfurase active site during pyridoxal phosphate-dependent desulfuration of cysteine; required for mitochondrial iron-sulfur cluster biosynthesis; exclusive to eukaryotes, implicated as eukaryotic supplement to the bacterium-derived Fe-S cluster (ISC) assembly apparatus; involved in regulation of iron metabolism; member of the LYR protein family
