Data

About the toolbox development

Almost 50 databases in one!

Environmental data integration

Integrated database

Combination of environmental data (Copernicus) with organism observation data (OBIS) can give valuable information on the living conditions of organisms (not publicly available data).

Most data publicly available, but a lot of time was spent on data integration to increase usability and overall value.

Tools

About the toolbox development
  • Enhanced Prediction Accuracy, utilizing in-house developed tools alongside state-of-the-art models.
  • Increased Reliability, combining multiple existing tools for easy comparison of results. Models are independently tested and selected based on their performance and accuracy.

Protein Thermostability

Optimal enzyme temperature

EC number & enzyme classification

pH

Similarity search (sequence and structure)

Metabolic enzyme cost (based on research article)

Protein Properties: aromaticity, instability index, flexibility, IVYWREL, etc.

Turnover rate prediction (Kcat)

Organism Growth Temperature prediction

Protein/Enzyme cellular localisation and GO terms

Identify novel enzymes
How to use the toolbox
1. Identifying novel enzymes
2. Search for good enzyme candidate

User has an organism of interest

Parameter prediction

  • EC number
  • Temperature
  • pH

Similarity search

  • Sequence
  • Structure
  • Reaction

AA sequence

What if you have 100 genomes? Enzymares pipeline allows WATERFALL FILTERING for enzyme candidates

  • Annotate all predicted genes with EC number predictions through deep learning models. Select EC number of interest. 100 000 proteins => 100 proteins
  • Homology search for validation (compare with experimentally validated structures). 100 proteins => 10 proteins
  • Determine which ones to test first, based on parameter prediction using the tools in the toolbox.
Search for suitable enzymes
