Bacteria’s amyloids display surprising structure

Protein clumps in S. aureus differ from those in Alzheimer’s, Parkinson’s

Clusters of a toxic bacterial protein have a surprising structure, differing from similar clumps associated with Alzheimer’s and Parkinson’s in humans, scientists report in the Feb.
