Gut Bacteria – Researchers have discovered that Bacteroides thetaiotaomicron, a commensal bacterium, requires a specific protein domain for survival in mammalian gut. This protein, Rho, contains an intrinsically disordered domain (IDR) which sequesters Rho molecules into an intracellular compartment. This mechanism increases Rho termination activity while altering gene expression patterns to enable B. thetaiotaomicron to colonize successfully the gut. Researchers engineered a B. thetaiotaomicron strain … Continue reading New Research Reveals How Gut Bacteria Colonize the Human Gut
