Structural basis for sugar translocation through maltoporin channels at 3.1 angstrom resolution

Structural basis for sugar translocation through maltoporin channels at 3.1 angstrom resolution

Trimeric maltoporin (LamB protein) facilitates the diffusion of maltodextrins across the outer membrane of Gram-negative bacteria. The crystal structure of maltoporin from Escherichia coli reveals an 18-stranded, antiparallel beta-barrel that forms the framework of the channel.
