Protein Family Models

This is a family of DNA-binding proteins. Members of this family form homodimers which bind DNA via a tweezer-like structure [1-3]. The conformation of the DNA is changed when bound to these proteins [3]. In bacteria, these proteins may play a role in DNA replication-recovery following DNA damage [1]. [1]. 12486730.

YbaB/EbfC family nucleoid-associated protein is a DNA-binding protein that may be involved in DNA repair

The role of this DNA-binding protein is unknown, but it has been expressed and crystallized. Its gene nearly always occurs next to recR and/or dnaX. It is restricted to Bacteria and the plant Arabidopsis. 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. Members of this family are found in a single copy per bacterial genome, but are broadly distributed. A member is present even in the minimal gene complement of Mycoplasm genitalium.
