Structural Analysis on Tail Fiber Protein gp37 of Polyvalent Phage Bp7
Several bioinformatics tools were used to predict and analyze the structure of protein gp37,the tail fiber protein of a polyvalent phage Bp7.The results were listed as follows:Tail fiber protein gp37 had a high homology with many T4-like phage strains,but far away from T4 phage.Conservation analysis of amino acid sequence of gp37 showed a mosaic character;the sequence was highly conserved at the N-terminal and variable at the C-terminal;there were Leucine zipper motifs at the C-terminal.Second structural analysis of gp37 showed that the second structure of gp37 was similar to that of T4,except α-helix domain at the end of C-terminal of gp37.These results will provide information for broadening the host range of phage Bp7 through gene modification of tail fiber gp37.
