The Carbohydrate-Active Enzymes Database (CAZy) is a knowledgebase specializing in enzymes that construct or hydrolyze glycosidic bonds in complex carbohydrates. It classifies these enzymes into glycoside hydrolase (GH), glycosyltransferase (GT), polysaccharide lyase (PL), carbohydrate esterase (CE), and auxiliary activities (AA) families based on conserved catalytic domain architectures revealed by amino acid sequence similarity. The database integrates multidimensional data including phylogenetic origin, genomic context, three-dimensional structures, and associated EC numbers for each characterized enzyme.
eggNOG-mapper v2 is a tool for functional annotation of large sets of sequences based on fast orthology assignments using precomputed eggNOG v5.0 clusters and phylogenies.
