[https://www.uniprot.org/uniprot/SUFS_BACSU SUFS_BACSU] Enzyme able to deliver sulfur to partners involved in Fe-S cluster assembly. Catalyzes the removal of elemental sulfur atoms from L-cysteine to produce L-alanine. Activity is stimulated 40-to 100-fold by SufU, which acts as a second substrate for this enzyme following release of Ala, and generating SufU.S. A mixture of SufS, SufU, Fra and L-cysteine is able to reconstitute Fe-S clusters on apo-aconitase (citB), reconstituting aconitase activity.<ref>PMID:20097860</ref> <ref>PMID:20822158</ref> <ref>PMID:21744456</ref>

== Publication Abstract from PubMed ==
 +
The biosynthesis of iron sulfur (Fe-S) clusters in Bacillus subtilis is mediated by a SUF-type gene cluster, consisting of the cysteine desulfurase SufS, the scaffold protein SufU, and the putative chaperone complex SufB/SufC/SufD. Here, we present the high-resolution crystal structure of the SufS homodimer in its product-bound state (i.e., in complex with pyrodoxal-5'-phosphate, alanine, Cys361-persulfide). By performing hydrogen/deuterium exchange (H/DX) experiments, we characterized the interaction of SufS with SufU and demonstrate that SufU induces an opening of the active site pocket of SufS. Recent data indicate that frataxin could be involved in Fe-S cluster biosynthesis by facilitating iron incorporation. H/DX experiments show that frataxin indeed interacts with the SufS/SufU complex at the active site. Our findings deepen the current understanding of Fe-S cluster biosynthesis, a complex yet essential process, in the model organism B. subtilis.
