Fig 4. Principal component analysis plot showing the distribution of acetonic extractives of the group B defined in Fig 3.

This group B is a chemically similar group of extractives based on major functional categorizations of chemicals found in the extracts. A matrix based on the interactions between the six studied TvGSTO and the five studied PcUre2p and these extractives determined using the fluorescence-based thermal stability assay and the competition experiments was used as input
