Figure 4: Structural superposition among the MAYV E1 homology model (orange cartoon) and the homologous proteins from Semliki Forest virus (grey) and Chikungunya virus (green). Cyan subunit is the E2 protein from Chikungunya virus. Side chain of Leu at positions 300 of MAYV E1 is reported as red stick model. Disulfide bonds are displayed as yellow sticks. Red areas in the β -strands of the Semliki Forest and Chikungunya virus E1 proteins denote the two-residue insertions found with respect to the MAYV E1 sequence. |
