Function

[SSB_HELPY] Plays an important role in DNA replication, recombination and repair. Binds to ssDNA and to an array of partner proteins to recruit them to their sites of action during DNA metabolism (By similarity).

Evolutionary Conservation

Publication Abstract from PubMed

Single-stranded DNA (ssDNA)-binding protein (SSB) plays an important role in DNA replication, recombination, and repair. SSB consists of an N-terminal ssDNA-binding domain with an oligonucleotide/oligosaccharide binding fold and a flexible C-terminal tail involved in protein-protein interactions. SSB from Helicobacter pylori (HpSSB) was isolated, and the ssDNA-binding characteristics of HpSSB were analyzed by fluorescence titration and electrophoretic mobility shift assay. Tryptophan fluorescence quenching was measured as 61%, and the calculated cooperative affinity was 5.4x10(7) M(-1) with an ssDNA-binding length of 25-30 nt. The crystal structure of the C-terminally truncated protein (HpSSBc) in complex with 35-mer ssDNA [HpSSBc-(dT)(35)] was determined at a resolution of 2.3 A. The HpSSBc monomer folds as an oligonucleotide/oligosaccharide binding fold with a Y-shaped conformation. The ssDNA wrapped around the HpSSBc tetramer through a continuous binding path comprising five essential aromatic residues and a positively charged surface formed by numerous basic residues.
