Folding and assembly of phage P22 tailspike endorhamnosidase lacking the N-terminal, head-binding domain.

Tryptic digestion of a thermal unfolding intermediate of the phage P22 tailspike endorhamnosidase produces an N-terminally shortened protein fragment comprising amino-acid residues 108-666 [Chen, B.-L. & King, J. (1991) Biochemistry 30, 6260-6269]. In the present work, the 60-kDa C-terminal fragment was purified to homogeneity from the tryptic digest by gel… CONTINUE READING
