Figure 4. Sequence Homology between Human and Bacterial E2s.
Alignment of human, Bacillus stearothermophilus (B. ste.), and A. vinelandii (A. vin.) tE2 sequences. Identical residues are bold and capitalized; similar residues are capitalized only. Helices (H) are indicated by shading; β sheets (S) are indicated by dotted boxes. The prokaryotic tE2s have two short β strands between H3 and S2 that are not present in human tE2, and two other β strands (S6 and S7) are shorter in human than in prokaryotic tE2.
