Sequence logos produced for the loop E region of different fungal MIP groups. The positions corresponding to the conserved NPA motif are used as the reference point and the position of Asn in the NPA motif is designated as ‘0”. All other amino acids are marked relative to this position. The arrows shown in cyan point to the residues from LE1 and LE2 positions that participate in the formation of the narrow selectivity filter. The acidic and basic residues that can form intra-helical salt-bridge interaction are indicated in the figure. The sequences logos were produced from the web server http://weblogo.berkeley.edu/logo.cgi.
