Figure 9From: Prediction of transmembrane helix orientation in polytopic membrane proteinsConservation of residues in PetL subunit of cytochrome b 6 f. Sequence logo for PetL subunit (11 sequences, pairwise sequence identity 13%–87%). Conserved residues Tyr7 from PetL and Ser85 from PetN form a possible interhelical hydrogen bond in 1Q90 (shown in spacefill).Back to article page
