Abstract. The bacteriophage fd gene 5 protein (G5P) binds strongly to single stranded DNA. Electrostatic interactions, involving ion pairing of positively charged lysine and arginine protein side chains with the negatively charged phosphates of four nucleotidyl units of DNA, are very important in this interaction process 1–r, implication of specific lysyl residues in the DNA-binding Author: C.

Geraldes, A. Sherry, L. Dick, C. Gray, D. Gray. The gene 5 protein of filamentous bacteriophage fd is a single-stranded DNA-binding protein that binds non-specifically to all single-stranded nucleic acid sequences, but in addition is capable of specific binding to the sequence d (GT5 G 4 CT 4 C) and the RNA equivalent r (GU 5 G 4 CU 4C), the latter interaction being important for translational by:   J.

After four rounds of primer-free genomic SELEX, most cloned sequences overlapped at a segment within gene 6 of the viral genome. This sequence segment was pyrimidine-rich and contained no stable secondary structures. Paradiso PR, Konigsberg W. Photochemical cross-linking of the gene 5 DNA complex from fd-infected cells.

Protein primed initiation and DNA polymerization By site-directed mutagenesis in the five most conserved regions of amino acid similarity found in the C-terminal portion of DNA polymerase and other eukaryotic-type DNA polymerases (see Fig.

2), it has been demonstrated that the C-terminal twothirds of the 29 DNA polymerase polypeptide. Almost every stage in the regulation of gene expression involves the interaction of proteins with specific nucleic acids sequences.

The identification of the nucleic acid recognition sequence of a given DNA-binding protein is therefore often the first step to. Hélène C () Metal ion-mediated specific interactions between nucleic acid bases of polynucleotides and amino acid side chains of polypeptides.

The unique feature of parallel G‐quadruplexes is the association of four separate strands held together by the hydrophobic stacking of large, planar hydrogen‐bonded DNA base quartets.

Titrations of poly[d(A)] or fd ssDNA with wild type, Y26F, Y34F, or Y41F gene 5 proteins resulted in perturbations of the nucleic acid near-UV CD bands, specific for the particular nucleic acid.
