Hypothesis
To develop a multicriterion system that describes CAZymes’ mechanisms and functional information more effectively than the existing EC number system.
Conclusion
The CAZac system enhances the ability to search and compare functional information across CAZyme families, addressing limitations of the existing EC classification.
Supporting Evidence
- The CAZy database has been providing reference classification for carbohydrate-active enzymes for over 30 years.
- The CAZac system allows complex searches in the CAZy database to uncover the evolution of substrate specificity.
- The study highlights the limitations of the existing EC number system in describing enzyme functions.
Takeaway
This study created a new tool called CAZac to help scientists understand how enzymes that break down carbohydrates work, making it easier to find and compare their functions.
Methodology
The CAZac system was developed to describe the mechanisms and activities of carbohydrate-active enzymes based on their sequence families.
Limitations
Less than 1% of sequences in the CAZy database have been functionally characterized, and many CAZyme substrates are not yet known or available.
