Figure 6

Correlation of protein abundances estimated by APEX vs . 2-DE based on aromaticity. Proteins predicted for Sd197 genome were sorted based on the frequency of aromatic amino acids F, W and Y in proteins and compared with proteins quantitated by APEX and 2-DE (Fig. 6a). Correlation of protein abundances estimated by APEX vs. 2-DE decreased with increase in non-polarity (>0.08 aromaticity values, R2= 0.63) and increase in polarity (<0.06 aromaticity values, R2= 0.59) compared to the overall abundance correlation.
