Fig. 3.
A single layer reconstructed protein array display of 967 out of approximately 2000 possible proteins that can potentially be expressed by P. gingivalis. The display shows one complete data set for a single growth condition. The plot is generated in any web browser by a separate Java program, D2g, that reads output from DTASelect.13 In the screen image above, the x-axis is pI (calculated) and the y-axis is log Mr, also calculated from the putative ORF. Each point on the plot also serves as a web-based link to the full entry in our P. gingivalis ORF database, the DTASelect summary for the particular protein represented by the dot, the mass spectral data and a BLAST link back to the original genome database. The hot links embedded in the plot make a convenient user interface to the many types of data used in our studies.
