    Protein Summary

    This structure is similar to previous JCSG structures 3gf8, 3liu, 3pay, 3r4r, 393142, likely involved in fimbrae formation. It demonstrate a novel form of oligomerization (dimer) through stand swapping.

     

    This type of proteins are highly abundant in gut bacteria, potentially important for host interaction. Further investigation will be conducted when more structures become available (all targets will be tagged 3gf8-related).

     

    This protein (BF1858) appears to be from the same operon as 393142(BF1861). It is noted that the putative operon consists of many proteins of similar fold.
