Chemical shift assignments of the rib domain in a cell surface protein from Limosilactobacillus reuteri

The Rib domain, a conserved structural element found in Gram-positive bacterial cell surface proteins, plays a role in bacterial virulence and is a potential target for vaccine development. Despite the availability of high-resolution crystallographic structures, the precise functional role of the Rib domain remains elusive. Here, we report the chemical shift assignments of the Rib domain from a cell surface protein of Limosilactobacillus reuteri, providing a foundational step toward understanding its potential involvement in host-bacteria interactions.
