Figure 2From: pkaPS: prediction of protein kinase A phosphorylation sites with the simplified kinase-substrate binding modelCumulative distribution of distances between successive sites in learning set proteins with multiple phosphorylated serine/threonine residues. The figure demonstrates that about two thirds of all distances are within the extended motif length of approximately 50 positions. The maximum distance, which exceeds the displayed x-axis, is 1759 amino acids.Back to article page
