Figure 3. . . Sequence alignments of a subset of simian adenovirus type B (SAdV-B) isolates identified in study of prevalence of adenoviruses in fecal samples from rhesus macaques, United States. The putative fused E3 CR1-αβ protein from isolate A1139 (see Table 2) and the corresponding separately encoded CR1-α and CR1-β proteins from isolate A1312 are shown. The N-terminal (N) and C-terminal (C) sections of the fused A1139 CR1-αβ proteins have been separately aligned with the A1312 CR1-α and CR1-β proteins, respectively. Gray shading indicates homologous regions, red font indicates identical residues, and underlining indicates hydrophobic regions.
