Figure 5. Structure-based sequence alignment of the N-terminal region.

The N-terminal sequences of Mfa4 and structurally related proteins with an exposed arginine in the β1β2-loop. The conserved arginine is depicted in red. Hydrophobic amino acids in the β1/β1a strand are depicted in blue and highlighted in grey. Horizontal arrows indicate β-strands (β1b is only present in Mfa4). The location of the N-terminal extension is indicated.
