[[http://www.uniprot.org/uniprot/SUFS_ECOLI SUFS_ECOLI]] Cysteine desulfurases mobilize the sulfur from L-cysteine to yield L-alanine, an essential step in sulfur metabolism for biosynthesis of a variety of sulfur-containing biomolecules. Component of the suf operon, which is activated and required under specific conditions such as oxidative stress and iron limitation. Acts as a potent selenocysteine lyase in vitro, that mobilizes selenium from L-selenocysteine. Selenocysteine lyase activity is however unsure in vivo.<ref>PMID:10829016</ref> <ref>PMID:12089140</ref> <ref>PMID:11997471</ref> <ref>PMID:12876288</ref> <ref>PMID:12941942</ref>
