GENE V PROTEIN (SINGLE-STRANDED DNA BINDING PROTEIN)GENE V PROTEIN (SINGLE-STRANDED DNA BINDING PROTEIN)
Structural highlights
Function[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). Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe 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-->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.
