Cysteine Desulfurases Mediating Sulfur Trafficking for the Biosynthesis of Fe-S Clusters
… to date include the participation of at least a cysteine desulfurase and an Fe-S cluster scaffold. The first step in sulfur mobilization for the assembly of Fe-S clusters as well as other thiocofactors within the cell involves a PLP-dependent enzymatic mechanism, catalyzed by cysteine …

Protein Specificity Dictates Proper Sulfur Transfer in the Biosynthesis of Thio-cofactors in Bacteria
… molecules is predominantly originated from L-cysteine through activation by cysteine desulfurases and is relayed to specific pathways involving the synthesis of thio-cofactors. In this dissertation, we reviewed recent methods for detection and quantification of bacterial thio-nucleosides used …

Biosynthesis and Functions of tRNA 2-Thiouridine in Bacillus subtilis
Cysteine desulfurases are PLP-dependent enzymes that catalyze the abstraction of sulfur from the free amino acid cysteine in a majority of organisms. Together with their sulfur acceptor proteins, these enzymes are required for the mobilization of sulfur for its incorporation into a wide variety of …

Investigations of conserved structure-function relationships and enzymatic evolution
… stress and iron starvation. SufS is the cysteine desulfurase enzyme responsible for the acquisition of sulfur and subsequent transfer to transpersulfurase SufE. Recent studies have provided several crystal structures of SufS including two variants displaying stalled intermediates of the …
