What it is Filled
A large group of enzymes that hydrolyse glycosidic bonds in carbohydrates and glycoconjugates, classified into families by sequence in the CAZy database and including amylases, cellulases, inulinases, dextranases, pectinases, alpha-glucosidases, beta-galactosidases and debranching enzymes such as amylo-alpha-1,6-glucosidase; glycoside hydrolases are essential in digestion, cell wall turnover and glycan processing, and are used industrially in food, biofuel and textile processing.
Why it exists Filled
Let an agent explain glycoside hydrolases and their classification, identify major enzyme kinds and their substrates, relay biological roles and industrial uses, and distinguish them from other carbohydrate-active enzymes.
Distinguishing features Filled
- Glycosidic bond hydrolysis
- Sequence-based families
- Retaining and inverting mechanisms
- Wide biological and industrial roles
What robots and AI may and may not do Filled
Must not
- Fabricate activity or classification data.
- Present enzyme supplements as cures for health conditions without evidence.
- Ignore safety rules when handling enzyme powders that can cause allergy.
Only with a human decision
- Using enzyme preparations in food or medicine for people.
May
- Describe the enzyme families and their functions from biochemical databases.
- Annotate sequences into families using recognised classification.
Moral aspects Filled
- Enzyme dusts are a recognised cause of occupational asthma.
- Classification databases are shared resources; errors spread to every user.
Who is affected
- Researchers
- Workers handling enzyme products
- Consumers
Owners Filled
Steward
Nobody owns the group; curators of carbohydrate enzyme databases maintain the classification.
Master systems
- Carbohydrate-active enzyme databases

- How should CAZy and EC databases be linked?
- The registry entry has merged aliases naming specific enzymes; should they be split off?
