FIG. 6.

Native gel electrophoresis. [³⁵S]methionine-labeled in vitro-translated proteins were incubated in gel shift binding buffer in the absence or presence of 0.5% SDS prior to being loaded on a native polyacrylamide gel. The positions of the likely dimeric (D) and monomeric (M) forms of BZLF-1 (Z) are indicated. The high-molecular-weight complexes formed by BZLF-1/3C‘d’ (H) are also indicated on the gel.
