'''GENE V PROTEIN (SINGLE-STRANDED DNA BINDING PROTEIN)'''<br />


==Overview==
==GENE V PROTEIN (SINGLE-STRANDED DNA BINDING PROTEIN)==
The crystal structure of the dimeric gene V protein of bacteriophage f1, was determined using multiwavelength anomalous diffraction on the, selenomethionine-containing wild-type and isoleucine-47--&gt;methionine, mutant proteins with x-ray diffraction data phased to 2.5 A resolution., The structure of the wild-type protein has been refined to an R factor of, 19.2% using native data to 1.8 A resolution. The structure of the gene V, protein was used to obtain a model for the protein portion of the gene V, protein-single-stranded DNA complex.

== Function ==
[https://www.uniprot.org/uniprot/G5P_BPF1 G5P_BPF1] Binds to DNA in a highly cooperative manner without pronounced sequence specificity. During synthesis of the single-stranded (progeny) viral DNA, prevents the conversion into the double-stranded replicative form. G5P is displaced by the capsid protein G8P during phage assembly on the inner bacterial membrane (By similarity).
