Figure 2. Periodicity analysis of the predicted TM α-helices of AUX/LAX proteins.

Figure 2

TM helices 2, 5, 7 and 10 of the AUX/LAX family have a periodicity in their predicted residue conservation and hydrophobicity. The linear sequence of each TM of A. thaliana AUX1 is projected on to a helical wheel, with the first amino acid of each helix set against a pale blue background. In each case the open arrow points to the centre of the hydrophobic face of the helix and the broken arrow to the centre of the conserved face of the helix. The length of the arrow is proportional to the strength of observed periodicity [32]. Loss-of-function missense mutations in AUX1 [28] in TM5, TM7 and TM10 are indicated in bold on a light background. Other predicted TM helices in AUX/LAX sequences show less convincing periodicity.
