Mobilization of the L: -cysteine sulfur for the persulfuration of the rhodanese of Azotobacter vinelandii, RhdA, can be mediated by the A. vinelandii cysteine desulfurases, IscS and NifS.

This C-terminal domain contains a pair of redox active cysteines and demonstrates thioredoxin-like activity by both binding to and mediating persulfide bond cleavage of sulfur-loaded IscS, the sulfide donor for [2Fe-2S] cluster assembly on ISU-type scaffold proteins.

Here, we have cloned and characterized human ISD11 and shown that human ISD11 forms a stable complex in vivo with the human cysteine desulfurase (ISCS), which generates the inorganic sulfur needed for Fe-S protein biogenesis.

Nfs-like proteins have cysteine desulfurase (CysD) activity, which removes sulfur (S) from cysteine, and provides S for iron-sulfur cluster assembly and the thiolation of tRNAs.

Nfs1 is a highly conserved mitochondrial cysteine desulfurase that participates in iron-sulfur cluster assembly as a sulfur donor.

In addition, we find that maximal fluorescence in the cytosol of mammalian cells requires the iron-sulfur cluster assembly proteins ISCU and NFS1.

Further, we show that apo-SufU is an activator of the cysteine desulfurase SufS by enhancing its activity about 40-fold in vitro.
Bacteria use three distinct systems for iron-sulfur (Fe/S) cluster biogenesis: the ISC, SUF, and NIF machineries.

Rhodaneses/sulfurtransferases are ubiquitous enzymes that catalyze the transfer of sulfane sulfur from a donor molecule to a thiophilic acceptor via an active site cysteine that is modified to a persulfide during the reaction.
In vitro YnjE can be efficiently persulfurated by the cysteine desulfurase IscS.
