Figure 4From: The domain architecture of large guanine nucleotide exchange factors for the small GTP-binding protein ArfThe conserved domains of the BIG/GBF subfamily: HUS domain. See Figure 3 legend for alignment details. The highly conserved HUS motif is boxed in blue. The gap in helix 5 domain is due to an insert in the Arabidopsis 3g43300 sequence, and may be resulting from a sequence annotation error.Back to article page
