Figure 3. Secondary peptide positional scan supports selection for Phe at the −2 position.

Figure 3

(A) Each peptide pool has threonine fixed as the phosphoacceptor and Arg fixed at the +2 position. Each bar represents one peptide pool. Shown are peptide pools where Z is a fixed residue at −2 ie X-X-X-Z-X-T-X-R-X-X where X is a degenerate position (adapted from [18]). (B) Table lists the log scores for each peptide pool. Phe at the −2 position has the highest log score (bold). (C) Sequence logo representation for secondary peptide scan. Position 0 is Thr and position +2 is Arg.
