Cysteine desulfurase; Master enzyme that delivers sulfur to a number of partners involved in Fe-S cluster assembly, tRNA modification or cofactor biosynthesis. Catalyzes the removal of elemental sulfur atoms from cysteine to produce alanine. Functions as a sulfur delivery protein for Fe-S cluster synthesis onto IscU, an Fe-S scaffold assembly protein, as well as other S acceptor proteins.

Probable cysteine desulfurase (NifS protein homolog). Homology to iscS of M. thermophila of 40% (sprot|ISCS_METTE) Catalyzes the removal of elemental sulfur from cysteine to produce alanine (By similarity). InterPro: Aminotransferase class-V (IPR000192) Pfam: aminotransferase class-V no signal peptide no TMHs ahpD: alkylhydroperoxidase AhpD; Family membership.

Putative co-chaperone HscB; Co-chaperone involved in the maturation of iron-sulfur cluster-containing proteins. Seems to help targeting proteins to be folded toward HscA; Belongs to the HscB family.

Cysteine desulphurases required for the mobilization of sulphur from cysteine. They are present in all organisms, where they are involved in iron-sulphur (Fe-S) cluster biosynthesis. Similar to sprot|CSD1_MYCLE (54%), to trembl|Q82WT8 (55%) and to tremblnew|BAB21542 (34%). Pfam (PF00266): Aminotransferase class-V Pfam (PF01041): DegT/DnrJ/EryC1/StrS aminotransferase family; Function unclear.
