==CRYSTAL STRUCTURE OF THE CYSTINE C-S LYASE C-DES==

FeS clusters are versatile cofactors of a variety of proteins, but the, mechanisms of their biosynthesis are still unknown. The cystine C-S lyase, from Synechocystis has been identified as a participant in ferredoxin FeS, cluster formation. Herein, we report on the crystal structure of the lyase, and of a complex with the reaction products of cystine cleavage at 1.8-, and 1.55-A resolution, respectively. The sulfur-containing product was, unequivocally identified as cysteine persulfide. The reactive persulfide, group is fixed by a hydrogen bond to His-114 in the center of a, hydrophobic pocket and is thereby shielded from the solvent. Binding and, stabilization of the cysteine persulfide represent an alternative to the, generation of a protein-bound persulfide by NifS-like proteins and point, to the general importance of persulfidic compounds for FeS cluster, assembly.
