FIG. 2.
Summary of budding phenotypes of M domain mutants. Each row represents a mutant with specific basic residue neutralizations (gray boxes) and/or acidic residue substitutions (black boxes). Budding phenotypes: wild-type level of release (+), less than 20% of wild-type release (−), between 20 and 50% of wild-type release (partial), near-twofold increase in release (enhanced).
