Experimental distribution of cuts and fragments, produced by the yeast
double mutant in enolase (taken from Nussbaum et al., Cleavage motifs of the
yeast 20 S proteasome beta subunits deduced from the digests of
enolase 1, Proc. Natl Acad. Sci. USA 95, 12504-12509).
Vertical bars indicate proteasomal cut sites; horizontal bars depict
the detected cleavage products.
