Proteins with a high propensity to aggregate can be largely prevented from doing so with surprisingly small changes to their primary structure. By using a combination of rational design and quantitative measurements of aggregation rates, we show that adding a single charge in specific "gatekeeper" regions is sufficient to change the timescale for amyloid fibril growth from minutes to weeks, thereby dramatically reducing the efficiency of this process.
