Each monomer consists of a N-terminal transmembrane region and a large cytoplasmic segment composed of a five-stranded antiparallel beta-sheet (middle/second) domain and a C-terminal alpha/beta-domain [4-7]. This is the beta domain which adopts a SH3-like barrel structure.

Each monomer consists of a N-terminal transmembrane region and a large cytoplasmic segment composed of a five-stranded antiparallel beta-sheet (middle/second) domain and a C-terminal alpha/beta-domain [4-7]. The N-terminal region consists of three membrane spanning helices (TM1, TM2 and TM3), TM2 and TM3 are represented in this entry. In the heptamer, the permeation pathway is formed by the packing of TM3s, flanked by TM1-TM2 helical hairpins [4].

Each monomer consists of a N-terminal transmembrane region and a large cytoplasmic segment composed of a five-stranded antiparallel beta-sheet domain (beta-domain, Pfam:PF00924) and a C-terminal alpha/beta-domain [1,2,3]. This is the C-terminal domain of McsS which, together with the middle beta-domain, creates a framework that connects to the cytoplasm through distinct openings [4-6].
