Strain-specific diversity of mucus-binding proteins in the adhesion and aggregation properties of Lactobacillus reuteri

Mucus-binding proteins (MUBs) have been revealed as one of the effector molecules involved in mechanisms of the adherence of lactobacilli to the host; mub, or mub-like, genes are found in all of the six genomes of Lactobacillus reuteri that are available. We recently reported the crystal structure of a Mub repeat from L. reuteri ATCC 53608 (also designated strain 1063), revealing an unexpected recognition of immunoglobulins. In the current...
