About Carbohydrate-Active enZYmes Database

CAZy is a specialist database for enzymes that degrade, modify, or create glycosidic bonds. Online since 1998, it presents genomic, structural, and biochemical information on carbohydrate-active enzymes (CAZymes). Data can be browsed by sequence-based families or by enzyme content in genomes, and new genomes and families are added regularly.

Pricing is not clearly stated.
