Hypothesis
The study aims to create a comprehensive database for protein-carbohydrate interactions to aid in understanding their biological significance and applications in drug design.
Conclusion
DIONYSUS provides extensive annotations of protein-carbohydrate interfaces, facilitating research in glycosciences and drug design.
Supporting Evidence
- DIONYSUS contains over 330k carbohydrate moieties in interaction with proteins.
- The database includes information from approximately 50k experimental structures involving 22k different proteins.
- Users can search the database using protein sequence and structure information or by carbohydrate binding site properties.
- DIONYSUS allows for comparative analysis of different sugar binding sites.
Takeaway
DIONYSUS is like a big library that helps scientists find out how proteins and sugars interact, which is important for understanding diseases and developing new medicines.
Methodology
The database was created by extracting and annotating carbohydrate-containing entries from the Protein Data Bank, followed by a systematic classification of protein-carbohydrate interfaces.
Limitations
The database may not include all possible protein-carbohydrate interactions due to the complexity and variability of these interfaces.
