BcsA and BcsB form a 1:1 stoichiometric complex spanning approximately 150 A perpendicular and 55 A parallel to the membrane. The complex is divided into a cuboid-shaped membrane-spanning region sandwiched between large cytoplasmic and periplasmic domains. BcsA contains four N-terminal and four C-terminal transmembrane-helices separated by a large intracellular loop (4/5-loop) that forms a GT-domain (aa 128 to 368). transmembrane domains 3-8 form a narrow channel for the translocating polysaccharide and BcsA's intracellular C-terminus (aa 575 to 759) contains a 6-stranded beta-barrel and a highly curved alpha-helical region that attaches the beta-barrel to the GT-domain. BcsB is a dome-shaped, beta-strand rich, periplasmic protein. Its N-terminal region forms the tip of the dome, whereas the C-terminal transmembrane-anchor interacts with BcsA. Two amphipathic helices further stabilize its interaction with BcsA and the periplasmic water-membrane interface. Domain structures. Modeling, overview |

recombinant catalytic domains of rice CesA8 cellulose synthase form dimers reversibly as the fundamental scaffold units of architecture in the synthase complex. The monomer is a two-domain, elongated structure, with the smaller domain coupling two monomers into a dimer. The catalytic core of the monomer is accommodated only near its center, with the plant-specific sequences occupying the small domain and an extension distal to the catalytic domain, structure comparison and modeling, overview.
