Interaction of bacterial flagellum filaments with skeletal muscle myosin.

Interaction of isolated bacterial flagellum filaments (BFF) and intact flagella from E. coli MS 1350 and B. brevis G.

Polymerization of bacteriophage T4 tail sheath protein mutants truncated at the C-termini.

Gene 18 of bacteriophage T4 encodes the contractile protein of the tail sheath. Previous work has shown that the full-length recombinant gene product (gp) 18 of 658 amino acid residues assembles in Escherichia coli cells into a long polysheath structure. However, the gp18 mutants truncated at the N-termini form insoluble aggregates similar to inclusion bodies.

Properties of recombinant bacteriophage T4 tail sheath protein and its deletion fragments.

A vector for expression of recombinant bacteriophage T4 tail sheath protein (gp18) under control of phage T7 promoter in Escherichia coli cells has been constructed. The entire length recombinant gp18 (659 amino acids) polymerizes in vivo into extended polysheaths. To study gp18 folding mechanisms, six vectors for expression of deletion mutants have been constructed.
