Proteome-wide expression changes on cellulose versus glucose visualized as a Cytoscape interaction network (Shannon et al, 2003). Nodes are proteins (circles) or KEGG/carbohydrate-active enzyme (CAZy) categories (yellow diamonds); edges are protein interactions defined by KEGG or CAZy databases. Protein node sizes show expression on cellulose as log₂ (Absolute Protein EXpression, APEX). Node colors are expression changes as cellulose/glucose log₂ protein ratios (MS1 peak area ratio, MPA ratio). Proteins less than twofold changed are white, higher on cellulose are graded orange, and higher on glucose are graded purple (see legend).
