Figure 5.

PCA of the relative abundances of proteins identified in the iTRAQ experiments for Synechocystis wild type and neutral site mutants containing a gfp module (with or without the constitutive promoter). The first component (x-axis) is responsible for 87.79% of the variation in the samples, and the second component (y-axis) is responsible for 8.79%. The heterologous proteins GFP (P42212) and NPTII (P00552, aminoglycoside 3′-phosphotransferase conferring resistance to neomycin/kanamycin), and a native small stress-related protein (P74485) are clearly separated from the bulk of the proteome (central protein cluster). This figure is available in black and white in print and in colour at DNA Research online.
