Surface Protein Dispersin of Enteroaggregative Binds Plasminogen That Is Converted Into Active Plasmin.

Dispersin is a 10.2 kDa-immunogenic protein secreted by enteroaggregative (EAEC). In the prototypical EAEC strain 042, dispersin is non-covalently bound to the outer membrane, assisting dispersion across the intestinal mucosa by overcoming electrostatic attraction between the AAF/II fimbriae and the bacterial surface.

Replication Protein A-1 Has a Preference for the Telomeric G-rich Sequence in Trypanosoma cruzi.

Replication protein A (RPA), the major eukaryotic single-stranded binding protein, is a heterotrimeric complex formed by RPA-1, RPA-2, and RPA-3. RPA is a fundamental player in replication, repair, recombination, and checkpoint signaling. In addition, increasing evidences have been adding functions to RPA in telomere maintenance, such as interaction with telomerase to facilitate its activity and also involvement in telomere capping in some conditions.
