Figure 7.

Sequence alignment of the Rac subfamily. The amino acid sequences of Rac GTPases were aligned using ClustalX, the secondary structures predicted using ESPript. Regions of the Rac proteins are indicated above the alignment; blue are the G domains, (G1, G2, G3, G4, and G5 with their respected motifs), purple are switch 1 and switch 2 domains, red is the Rho insert, green is the polybasic region, and black is the CAAX box. Blue frames are indicators of the conserved residues; white letters in red boxes represent identity, red letters in white boxes represent similarity.
