| Data class | Domain; |
| Predictors |
PROSITE; PS51674; 4FE4S_WBL |
Name | 4Fe-4S WhiB-like (Wbl)-type iron-sulfur binding domain |
| Function | Wbl-mediated transcription regulation is dependent upon the presence or absence and state (nitrosylated or non-nitrosylated) of the [4Fe-4S] cluster. |
| Scope(s) |
Bacteria Actinomycetes Viruses Timquatrovirus |
| Example(s) | Q6MX01 (WHB7A_MYCTU); |

| case <FTGroup:1> | |
| COFACTOR | Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; Note=Binds 1 [4Fe-4S] cluster per subunit. Following nitrosylation of the [4Fe-4S] cluster binds 1 [4Fe-8(NO)] cluster per subunit.; |
| PTM | The Fe-S cluster can be nitrosylated by nitric oxide (NO). |
| PTM | Upon Fe-S cluster removal intramolecular disulfide bonds are formed. |
