Biochem/physiol Actions

L-Arabinose is the naturally occurring isomer and is a constituent of plant polysaccharides. Most bacteria contain an inducible arabinose operon that codes for a series of enzymes and transporters that allows L-arabinose to be used as the sole carbon source in microbial culture.

The microbiota confers host protection by limiting the colonization of pathogenic bacteria in the gut, but the mechanisms by which pathogens overcome colonization resistance remain poorly understood. Using a high-density transposon screen in the enteric pathogen Citrobacter rodentium, we find

Studying gene function in the post-genome era requires methods to localize and inactivate proteins in a standardized fashion in model organisms. While genome-wide gene disruption and over-expression efforts are well on their way to vastly expand the repertoire of Drosophila
