Figure 1.

Number and functional categories of S. cerevisiae proteins containing three or more consecutive prolines. (A) Number of yeast proteins containing polyPro stretches with the indicated consecutive prolines. Formins Bni1 and Bnr1 are the only yeast proteins with polyproline stretches with 12 or more prolines. (B) GO functional categories significantly overrepresented in the 549 yeast genes containing a polyPro stretch with at least three consecutive prolines. Bars represent the number of genes found in each category and the P-value is indicated for each category.
