Adsorption of bacteriophages phi 29 and 22a to protoplasts of Bacillus subtilis 168 is described. The number of binding sites on bacilli and protoplasts is determined for each phage. Bacilli and protoplasts possess roughly the same number of sites per unit area for phi 29, i.e., approximately 700 sites per bacillus. There are also approximately 700 sites per bacillus for 22a, but only about one-third as many sites per unit area on the protoplast surface. A model for phi 29 adsorption is proposed.
本文描述了噬菌体phi 29和22a对枯草芽孢杆菌168原生质体的吸附作用。测定了每种噬菌体在杆菌和原生质体上的结合位点数。对于phi 29,杆菌和原生质体每单位面积的位点数量大致相同,即每个杆菌约有700个位点。对于22a,每个杆菌也约有700个位点,但原生质体表面每单位面积的位点数量只有其三分之一左右。本文还提出了phi 29吸附的模型。
