FIG. 1.

Schematic representations of the GFP fusion proteins. The full-length HPV-11 E2 protein consists of the N, H, and C domains, each denoted by a different boxed symbol. The amino acid residues of the E2 protein expressed in each fusion protein are indicated. Mutations of the H domain are also illustrated. The GFP moiety is placed at the amino terminus of each fusion protein and is represented by an oval. The calculated molecular masses (kilodaltons) are given at the right; ∗ signifies the dimeric form of the protein when the C domain is present.
