From: Detecting pore-lining regions in transmembrane protein sequences
Correctly predicted stoichiometries of three multimeric pore complexes. Bottom-up view of the heterodimeric maltose transporter malFG (left, 2R6G chain F), homotetrameric inward rectifier potassium channel KirBac1.1 (centre, 1P7B) and heterohexameric formate dehydrogenase (right, 1KQG chain B). Stoichiometry relates to the pore-lining membrane region only–extramembranous chains or those that do not line the pore are excluded. Complexes are coloured by chain, with the Pore-Walker predicted location of the pore shown by yellow spheres.
