Sialic acid transporters (SiaT) are required for sialic acid uptake in a number of human pathogens and are of interest as targets for antimicrobial drug development. Here the authors present the substrate bound SiaT structure from the uropathogen Proteus mirabilis and provide insights into the mechanism of sialic acid transport.
