In molecular biology, bacterial DNA binding proteins are a family of small, usually basic proteins of about 90 residues that bind DNA and are known as histone-like proteins. [1] [2] Since bacterial binding proteins have a diversity of functions, it has been difficult to develop a common function for all of them.
DNA-binding proteins from starved cells (Dps) are bacterial proteins that belong to the ferritin superfamily and are characterized by strong similarities but also distinctive differences with respect to "canonical" ferritins.
Single-strand DNA-binding protein (SSB) is a protein found in Escherichia coli (E. coli) bacteria, that binds to single-stranded regions of deoxyribonucleic acid (). [1] Single-stranded DNA is produced during all aspects of DNA metabolism: replication, recombination, and repair.
A distinct group of DNA-binding proteins are the DNA-binding proteins that specifically bind single-stranded DNA. In humans, replication protein A is the best-understood member of this family and is used in processes where the double helix is separated, including DNA replication, recombination and DNA repair. [18]
In ICP8, the herpes simplex virus (HSV-1) single-strand DNA-binding protein (ssDNA-binding protein (SSB)), the head consists of the eight alpha helices.The front side of the neck region consists of a five-stranded beta-sheet and two alpha helices, whereas the back side is a three-stranded beta-sheet The shoulder part of the N-terminal domain contains an alpha-helical and beta-sheet region.

DnaA is a protein that activates initiation of DNA replication in bacteria. [1] Based on the Replicon Model, a positively active initiator molecule contacts with a particular spot on a circular chromosome called the replicator to start DNA replication. [2] It is a replication initiation factor which promotes the unwinding of DNA at oriC. [1]
This DNA loop formation allows H-NS to control gene expression. [2] Relief of suppression by H-NS can be achieved by the binding of another protein, or by changes in DNA topology which can occur due to changes in temperature and osmolarity, for example. [6] The CTD binds to the bacterial DNA in such a way that inhibits the function of RNA ...
Ter-binding proteins are found in some bacterial species, and include the Tus protein which is part of the common Ter-Tus binding domain. They are required for the termination of DNA replication and function by binding to DNA replication terminator sequences, thus preventing the passage of replication forks. [1] The termination efficiency is ...
