[https://www.uniprot.org/uniprot/CSDE_ECOLI CSDE_ECOLI] Stimulates the cysteine desulfurase activity of CsdA. Contains a cysteine residue (Cys-61) that acts to accept sulfur liberated via the desulfurase activity of CsdA. May be able to transfer sulfur to TcdA/CsdL. Seems to support the function of TcdA in the generation of cyclic threonylcarbamoyladenosine at position 37 (ct(6)A37) in tRNAs that read codons beginning with adenine. Does not appear to participate in Fe/S biogenesis.<ref>PMID:15901727</ref> <ref>PMID:20054882</ref> <ref>PMID:23242255</ref>

Sulfur incorporations both in the biosynthesis of sulfur-containing cofactors and in the sulfur-modifications of certain tRNAs are all mediated by the sulfur initially delivered from the cysteine desulfurases. Sulfur generated as persulfide from cysteine is transferred to the sulfur acceptor protein to further allow delivery to the required steps within an enzymatic process. CsdA which is one of the three cysteine desulfurases identified in Escherichia coli transfers sulfur to the non Fe-S sulfur-acceptor CsdE, however, the consequence of CsdE accepted sulfur is mostly unknown. In this study, we report the 2.4A structure of free CsdE determined using X-ray crystallography, and compare the structure with the CsdE structure determined using NMR and also CsdE within the crystal CsdA-CsdE complex. Further analysis suggests that the positive electrostatic potential surfaces of CsdE may mediate interaction with a yet unidentified protein or possibly tRNA to deliver sulfur.
