This entry includes small conductance mechanosensitive channels (MscS), which assembles to a homoheptameric complex [1-6]. 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.	Domain

This entry includes small conductance mechanosensitive channels (MscS), which assembles to a homoheptameric complex [1-6]. 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].	Domain
