Figure 2From: Quantitative proteomics of nutrient limitation in the hydrogenotrophic methanogen Methanococcus maripaludisExperimental design, computational. The effect of each nutrient limitation was assessed by comparing its proteome to that from the two other nutrient limitations, thus providing two control conditions for each condition under study, green, H2-limitation; orange, nitrogen limitation; blue, phosphate limitation; light colors, light isotope (14N); dark colors, heavy isotope (15N).Back to article page
