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
