Description
Members of the WhiB-like (Wbl) family are found exclusively in actinobacteria and are implicated in the regulation of developmental processes. All WhiB-like proteins have four conserved cysteine residues where two of them are in a C-X-X-C motif. The four cysteine residues are proposed to act as the ligands for a [4Fe-4S] cluster. Wbl-mediated transcription regulation is dependent upon the presence or absence and state (nitrosylated or non-nitrosylated) of the [4Fe-4S] cluster [1,2,3].
The profile we developed covers the entire Wbl-type 4Fe-4S domain.
