Neutron scattering study of the solution structure of bacteriophages Pfl and fd

This paper presents the mass unit length and cross-sectional radius of gyration of Pfl and fd in solution as determined by low angle neutron scattering. The results support the view that the phage are similar in structure and partly favour a model for Pfl which has 22 subunits/axial repeat. It is also shown that Pfl undergoes a reversible temperature-induced structural change in solution. (Auth.)
