Cysteine sulfinate desulfinase; 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.

Murein L,D-transpeptidase; Catalyzes the formation of a meso-diaminopimelyl- meso-diaminopimelyl crosslink; Derived by automated computational analysis using gene prediction method: Protein Homology.

Cysteine desulfurase; Part of SUF system involved in inserting iron-sulfur clusters into proteins; in Escherichia coli this protein forms a complex with SufBD; the SufBCD complex stimulates the cysteine desulfurase SufS in conjunction with SufE; Derived by automated computational analysis using gene prediction method: Protein Homology.

Cysteine desufuration protein SufE; Participates in cysteine desulfuration mediated by SufS. Cysteine desulfuration mobilizes sulfur from L-cysteine to yield L- alanine and constitutes an essential step in sulfur metabolism for biosynthesis of a variety of sulfur-containing biomolecules. Functions as a sulfur acceptor for SufS, by mediating the direct transfer of the sulfur atom from the S-sulfanylcysteine of SufS, an intermediate product of cysteine desulfuration process; Belongs to the SufE family.

With SufCD activates cysteine desulfurase SufS; Derived by automated computational analysis using gene prediction method: Protein Homology.

Functions as a scaffold on which iron-sulfur clusters ([2Fe-2S]; [4Fe-4S]) are assembled; forms a homodimer; similar to IscA protein; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the HesB/IscA family.
