A Novel l-Cysteine/Cystine C-S-Lyase Directing [2Fe-2S] Cluster Formation of SynechocystisFerredoxin*
Iron-sulfur proteins acquire their clusters by posttranslational assembly. To identify components involved in this process an in vitro assay for holoprotein formation was established using theExpand

Crystal structure of the cystine C-S lyase from Synechocystis: stabilization of cysteine persulfide for FeS cluster biosynthesis.
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 aExpand
