The Escherichia coli single‐strand DNA binding protein (SSB) is essential to viability where it functions to regulate SSB interactome function. Here it binds to single‐stranded DNA and to target proteins that comprise the interactome. The region of SSB that links these two essential protein functions is the intrinsically disordered linker.
Structural dynamics of E. coli singlestranded DNA binding protein
Single-stranded binding proteins ( SSBs) are a class of proteins that have been identified in both viruses and organisms from bacteria to humans. Viral SSB Although the overall picture of human cytomegalovirus (HHV-5) DNA synthesis appears typical of the herpesviruses, some novel features are emerging. Structure

In E. coli, this protein is a tetramer known as single-stranded-binding (SSB) protein, which the ssDNA winds itself around, while in T4 and T7, these proteins are monomers known as gp32 and gp2.5, respectively.

Single-Stranded DNA-Binding Proteins (SSBs) A.L. Eggler, in Encyclopedia of Genetics, 2001 Structure of SSBs: How Do They Bind DNA? SSBs from all organisms are, for the most part, functional homologs. Sequence similarity between various SSBs is limited; however, they share a DNA-binding motif called the OB fold.
Singlestranded DNAbinding protein Stock Image C035/8205 Science
Single strand binding protein (ssb protein) binds to separated strands of DNA and prevents reannealing. Primase complexes with helicase, creates RNA primers (pppAC(N) 7-10) on the strands of the open duplex 2 (Primase+helicase constitute the Primosome).
Singlestranded DNAbinding protein Stock Image C015/3229 Science
In one model, semiconservative replication, the two strands of the double helix separate during DNA replication, and each strand serves as a template from which the new complementary strand is copied; after replication, each double-stranded DNA includes one parental or "old" strand and one "new" strand.
SingleStranded Binding Protein (SSB) Structure And Function
Single-stranded DNA (ssDNA) in a cell is highly prone to degradation, so cells shield ssDNA from nucleases by coating it with ssDNA-binding proteins (SSBs). In eukaryotes, the canonical SSB is a.
SingleStranded DNABinding Protein Interactions Keck Lab UWMadison
Overview. Single-stranded DNA-binding protein (SSB) binds to single-stranded regions of DNA. This binding serves a variety of functions - it prevents the strands from hardening too early during replication, it protects the single-stranded DNA from being broken down by nucleases during repair, and it removes the secondary structure of the.

The recognition of single-stranded DNA (ssDNA) is integral to myriad cellular functions. In eukaryotes, ssDNA is present stably at the ends of chromosomes and at some promoter elements. Furthermore, it is formed transiently by several cellular processes including telomere synthesis, transcription, and DNA replication, recombination, and repair.

In bacteria, these proteins are known as single-stranded DNA binding proteins (SSBs) (7, 8). Escherichia coli SSB is a homotetramer, Figure 1A. Each monomer features a structured DNA-binding domain (residues 1-112) and a long and disordered C-terminal tail (residues 116-177) containing a highly acidic tip.

Biochemical study indicates that RPA can bind ssDNA in three states (illustrated in Figure 7 (b) ): (1) binding of OB folds A and B occludes about 10 nucleotides, (2) binding of OB folds A, B and C occludes 12-23 nucleotides, and (3) binding of the four OB folds occludes 28-30 nucleotides ( Arunkumar et al., 2003; Bastin-Shanower and Brill, 2001.
Structural dynamics of E. coli singlestranded DNA binding protein
Single-stranded DNA (ssDNA) binding proteins (SSBs) are critical in maintaining genome stability by protecting the transient existence of ssDNA from damage during essential biological processes, such as DNA replication and gene transcription. The single-stranded region of telomeres also requires protection by ssDNA binding proteins from being.
Peter Schmieder Intecation of singlestrand binding protein
1. Introduction Central to many genome-maintenance machineries are single-stranded DNA binding proteins (SSBs). These SSB proteins play a vital role in the maintenance of genomes by binding exclusively and transiently to ssDNA intermediates during DNA replication, recombination, and repair.

Replication protein A (RPA) is a heterotrimeric protein complex and the main single-stranded DNA (ssDNA)-binding protein in eukaryotes. RPA has key functions in most of the DNA-associated metabolic pathways and DNA damage signalling. Its high affinity for ssDNA helps to stabilise ssDNA structures and protect the DNA sequence from nuclease attacks.
SingleStranded Binding Protein Structure And Function
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 ( DNA ). [1] Single-stranded DNA is produced during all aspects of DNA metabolism: replication, recombination, and repair.

Using single-molecule imaging and manipulation, the authors show linker histone H1 preferentially forms phase-separated droplets with single-stranded nucleic acids over double-stranded DNA and.
