sbmlcore 0.1.3

Constructs core features table for the application to machine learning models

sbml-core

Collection of core classes and functions for structure-based machine learning to predict antimicrobial resistance.

This is a pre-release alpha version - it may not be fully functional for your requirements and it is also subject to change with no notice!

See notebooks walkthrough.ipynb and addition_methods_walkthrough.ipynb for quick user tutorials.

Included features

Changes in Amino Acid Properties

• Volume
• Hydropathy scales: Kyte-Doolittle (paper) and WimleyWhite (paper)
• Molecular weight
• Isoelectric point

Secondary structure

• STRIDE (website and paper)

Solvent accessible surface areas

• FreeSASA (paper)
• STRIDE (website and paper)

Likelihood of changes in protein function

• SNAP2 (server and paper)

Effect of mutation on protein stability

• DeepDDG: a more recent neural network that claims to outperform DUET, PopMusic etc. (paper and server). Can do all possible mutations in one job.

Structural distances

• Distances between mutated residues and any atom/group of atoms of interest. Uses MDAnalysis (paper1 and paper2).

To potentially include at a later stage

• Secondary structure: DSSP (do not anticipate much difference to STRIDE)
• Protein stability:
  1. StabilityPredict. Online metapredictor, single amino acid at a time. Josh used in the pncA paper but had to contact them directly to run the entirity of PncA. (paper)
  2. DynaMUT. Also claims to outperform DUET etc. (paper). Can process a list of specified mutations in one job. (server)
