Internal 3 TMS repeats in 6 TMS proteins. A (left). Hydropathy plot of MalG (TC# 3.A.1.1.1), a six TMS membrane porter. Blue lines denote Hydropathy; Red lines denote Amphipathicity; Orange bars mark transmembrane segments as predicted by HMMTOP. B (right). TMSs 1–3 of gi220933130 aligning with TMSs 4–6 of gi255331744 yielded a comparison score of 10.9 S.D. with 40.3% similarity and 27.7% identity. The numbers at the beginning of each line refer to the residue numbers in each of the proteins. TMSs are indicated in red lettering. Vertical lines indicate identities; colons indicate close similarities, and periods indicate more distant similarities.
