Truncation mutants of δ and CP-δ.
(a) SDS-PAGE showing five purified proteins. (b) Negative-staining EM images. δ(1–241), δ(1–162) and the midi-fusion all formed fiber-shaped molecules. Some of these fibers are highlighted by arrows. Scale bar, 500 Å. (c) Length measurements for the two δ truncation mutants in comparison with the full-length δ. (d) Length measurements for the midi-fusion protein in comparison with δ(1–162).
