Bacteriophage M13 procoat protein inserts into the plasma membrane as a loop structure.

The major coat protein of bacteriophage M13 is synthesized as a precursor, the procoat, with a typical leader (signal) sequence of 23 residues at its NH2-terminus. A fusion protein that contains the NH2-terminal 141 residues of cytoplasmic ribulokinase and all but the first ten residues of M13 procoat was made. The fusion protein inserts into the plasma… CONTINUE READING
