Amino Acid Sequence Alignment of Members of the UPS Family.

Amino acids are given with standard single-letter designation, and dashes indicate gaps. Residues are shown in white letters on black if five or more sequences have identical residues at the aligned position. Gray background indicates similar amino acids, and asterisks indicate conserved amino acids sharing the consensus sequence A-x(4)-G-K-S (“Walker A” motif). Gray boxes above the sequences indicate the positions of 10 potential transmembrane domains (TM), and the connecting lines indicate potential outside and inside domains as predicted by TMHMM version 2.0 (http://www.cbs.dtu.dk/services/TMHMM/). VuA3, protein A3 from Vigna unguiculata.
