Figure Lengend Snippet: ( A ) Heatmaps depicting the specificities of c-Abl, Fer, EPHB1, and EPHB2. Enrichment scores were log 2 -transformed and are displayed on a color scale from blue (disfavored sequence features, negative value), to white (neutral sequence features, near zero value), to red (favored sequence features, positive value). Values in the heatmaps are the average of three replicates. ( B ) Sequences of consensus peptides identified through X 5 -Y-X 5 screens, compared with previously reported SrcTide and AblTide sequences. ( C ) Phosphorylation kinetics of five consensus peptides against five kinases. Initial rates were normalized to the rate of the cognate consensus peptide. All peptides were used at a concentration of 100 μM, and the kinases were used at a concentration of 10–50 nM. Error bars represent the standard deviation from at least three measurements. Figure 2—source data 1. Position-specific amino acid enrichment matrices from the tyrosine kinase X 5 -Y-X 5 library screens. Matrices calculated with and without inclusion of multi-tyrosine sequences are provided.
