Figure 6: Muscle and liver glycogenolysis.
From: Quantitative maps of protein phosphorylation sites across 14 different rat organs and tissues
The chemical pathway for glycogenolysis is shown as are the phosphorylated enzymes involved in each of the steps identified in rat or human skeletal muscle (left) or in liver (right). The protein isoforms with the greatest number of identified phosphorylation sites were chosen for visualization. The number of phosphorylation sites on each of the proteins is indicated by small circles that are colour coded according to the amino acid phosphorylated with yellow for tyrosine, purple for threonine and blue for serine. The normalized protein intensity count is provided next to each protein.
