Welcome to the Carbohydrate-Active enZYmes Database
CAZy now offers a platform facility that provides either automatic annotation or human curation services for your data.
The fully automatic annotation is to provide users with high quality and most up-to-date results.
However, since automatic annotation is never error-free, and while we are working at constantly improving our pipeline, a "human curation" service also exists for the highest-quality analyses.
Because human curation requires expertise and time, and because such resources are limited, a query for human curation will have to be validated by the CAZy scientific committee.

The CAZy database describes the families of structurally-related catalytic and carbohydrate-binding modules (or functional domains) of enzymes that degrade, modify, or create glycosidic bonds.
Online since 1998, CAZy is a specialist database dedicated to the display and analysis of genomic, structural and biochemical information on Carbohydrate-Active Enzymes (CAZymes).
CAZy data are accessible either by browsing sequence-based families or by browsing the content of genomes in carbohydrate-active enzymes. New genomes are added regularly shortly after they appear in the daily releases of GenBank.
New families are created based on published evidence for the activity of at least one member of the family and all families are regularly updated, both in content and in description.
An original aspect of the CAZy database is its attempt to cover all carbohydrate-active enzymes across organisms and across subfields of glycosciences. Please let us know if some families have escaped our attention, we will be happy to add them !
For a more extensive encyclopedic resource on the particular features of carbohydrate active enzymes, please visit CAZypedia, a web site driven by the scientific community that studies these enzymes.
PULDB is a database of Polysaccharide Utilization Loci (PULs) in Bacteroidetes. PULDB displays information on experimentally determined and predicted PULs for a number of Bacteroidetes genomes.
A new reference for the CAZy database : We summarized the recent changes in the CAZy database, and evolution during the last eight years in an article published the Nucleic Acids Research (Database Issue), with a specific focus on functional annotations.
