Homologous Superfamily

Nucleoid-associated protein YbaB-like domain superfamily (IPR036894)

Short name: YbaB-like_sf

Overlapping entries


This entry represents a domain superfamily of DNA-binding proteins. It is restricted to bacteria and plants. Members of this family form homodimers which bind DNA via a tweezer-like structure [PMID: 12486730, PMID: 19594923, PMID: 19208644]. The conformation of the DNA is changed when bound to these proteins [PMID: 19208644]. In bacteria, these proteins may play a role in DNA replication-recovery following DNA damage [PMID: 12486730]. The plant form contains an additional N-terminal region that may serve as a transit peptide and shows a close relationship to the cyanobacterial member, suggesting that it is a chloroplast protein.

The crystal structure YbaB from Haemophilus influenzae revealed a tight dimer with a three-layer structure (beta/alpha/beta) [PMID: 12486730].
