@sudarshanb259 Yes. We restrict the dataset (ie. remove all peptides with log P > 0) then run the algorithm in order to find the interesting cases of peptides that do aggregate but at least less due to the hydrophobic effect.

@AlexandervanTe1 So, your ML model is able to predict peptides of high AP, and surprisingly, for some of these peptides have log P < 0. And enthalpy (intermolecular interaction) plays a major role in the aggregation rather than entropy (hydrophobicity). Have I understood it properly?

3. This is the interesting part, that it does aggregate despite being soluble (at least as far as log P < 0 = soluble) means the molecules are interacting in an attractive fashion in the way we would expect for a self-assembling nanomaterial.

@AlexandervanTe1 @scotch_research 3. A basic question. When you write "a soluble hexapeptide that aggregates in water" in Figure 2, is it soluble in water? If so, how can it still form aggregates?

Ahh sorry i misunderstood. During the CGMD simulation there are 300 peptides in the simulation box. The datasets are 8000 (20^3) for tripeptides, up to 64,000,000 (20^6) for hexapeptides.

@AlexandervanTe1 Thanks. With a dataset of 300, you are able to capture the feature-target relationship to a good extend. Great!

2. sum(SP2) is the total number of SP2 carbon atoms, max ASA and Bulkiness are described in the references listed, twitter character limit ties my hands a bit here. Briefly, maxASA is the highest ASA for an amino acid in the tripeptide Gly-X-Gly in all biophysical conformations.
Sudarshan@sudarshanb259

@AlexandervanTe1 @scotch_research 2. In the Judred parameters, what does sum(SP2) means? Is it the total number of SP2 hybridized atoms? What is Max SASA and how do you define bulkiness?
