Researchers Resolved Structure of Pseudomonas Protein
Scientists have determined the full-length structural conformation of the CdrA protein found in Pseudomonas aeruginosa.
Updated on Sept. 18, 2026 in Life Sciences
Researchers successfully identified the full-length structural conformation of the CdrA protein, a key fibrillar adhesin produced by the bacterium Pseudomonas aeruginosa. This structural insight provides a clearer understanding of how the protein facilitates bacterial surface attachment and biofilm formation.
Why it matters
Understanding the precise structure of bacterial adhesins is a crucial step in unraveling how pathogens colonize surfaces. These findings provide a structural foundation that could guide the design of future therapies aimed at disrupting biofilm formation.
The CdrA structure was characterized by an extension domain of tandem repeat modules and an adhesive domain containing two claw-like subdomains. Structural restraints were generated using cryo-electron microscopy and solid-state NMR.
The players
Pseudomonas aeruginosa
This bacterium is a common pathogen known for producing proteins that facilitate chronic infections through the formation of biofilms.
The details
The team utilized advanced computational methods to refine the full-length model of CdrA, which is central to the formation of bacterial aggregates. The new data delineates the architectural components that allow the bacterium to build robust biofilms.
