Fig. 5

The frequency differences of 20 × 20 amino acid pairs between carbonylated sites and non-carbonylated sites of lysine, arginine, threonine and proline. The amino acid pair with red box indicates an over-representation in carbonylated sites (positive data) comparing to non-carbonylated sites (negative data); on the other hand, green box means an under-representation
