Welcome to CAZypedia!
The Encyclopedia of Carbohydrate-Active Enzymes.
Cazypedia logo big.png


CAZypedia has been initiated as a community-driven resource to assemble a comprehensive encyclopedia of the "CAZymes," the carbohydrate-active enzymes and associated carbohydrate-binding modules involved in the synthesis and degradation of complex carbohydrates. CAZypedia is inspired by, and closely connected with, the actively curated CAZy Database. It's probably fair to say that CAZypedians are, like our friends at the CAZy DB, a group of "biocurators."
If you are new to the CAZyme classification, "Sorting the Diverse" by Professors Gideon Davies and Michael Sinnott (The Biochemist, 2008, vol. 30, part 4, pp. 26-32) provides an excellent introduction and historical perspective.


CAZypedia initially focussed on the Glycoside Hydrolase Families defined in the CAZy Database, and we continue to strive for complete coverage of this diverse class of enzymes. Other catabolic and anabolic CAZymes, as well as Auxiliary redox enzymes and non-catalytic Carbohydrate Binding Modules, continue to be incorporated as interest and engagement from the scientific community grows. In addition, there is a Lexicon of terms relevant to CAZymes and carbohydrate chemistry.
These and other aspects of CAZypedia's content can be accessed through the menus on the left side of each page.

How CAZypedia works

CAZypedia is built on authoring and editing principles similar to those of other expert-based online encyclopedias (cf. Citizendium, Scholarpedia). All contributors to CAZypedia, from the Authors to the Board of Curators, are experts in the field. Transparency is achieved through the use of contributors' real names and published biographies in CAZypedia. Individual entries in CAZypedia are managed by Responsible Curators, who are responsible for selecting expert Authors and coordinating author contributions on individual pages. Selection of Responsible Curators, based on their specialist expertise and ability to participate in the active maintenance of entry content, is handled by the Senior Curators.
More information on CAZypedia's content and editorial policies is available here.
A short lecture and a set of slides presenting CAZypedia are freely available here.
An article describing CAZypedia's genesis and evolution has been published in the journal Glycobiology.


If you would like to get involved with CAZypedia or suggest an improvement, please contact the Board of Curators.

Latest news

23 June 2021 A free CAZypedia webinar: Check out the presentation on CAZypedia by Senior Curator Elizabeth Ficko-Blean, which was part of a webinar on Recent Advances in Carbohydrate-Active Enzymes organized by Stefan Janecek. Stefan also gave a talk on alpha-amylase bioinformatics, and Nicolas Terrapon gave an overview of the CAZy database in a presentation entitled "Carbohydrate-Active EnZymes Annotation in the High-Throughput Era". More information on the webinar can be found here, and you can watch all three lectures for free on YouTube.

31 May 2021 Celebrating CAZy: The B.A. Stone Award for Excellence in Plant Polysaccharide Biochemistry was awarded to CAZy founder Bernard Henrissat today. CAZy, CAZypedia, and Prof. Bruce Stone have a long, intertwined history, and today we celebrate Bernie's insight to create a sequence-based classification of the Carbohydrate-Active EnZymes, starting with the cellulases.

30 March 2021 Presenting the gagalicious CBM87 family: CBM87 members are found appended to fungal galactosaminogalactan deacetylases that are involved in biofilm formation. The CBM87s have the unusual - but not unheard of - property of extending the enzyme's catalytic site. The GAG-binding CBM87 CAZypedia page has been authored by Natalie Bamford with Lynne Howell acting as responsible curator. Go gaga for the GAG-binding CBM87 family here.

2 December 2020: It's a bird, it's a plane, it's CBM14! From start to finish in superhero time, the lectin-containing, chitin-binding CBM14 page is up and running. This is thanks to the heroic efforts of author Eva Madland with Elizabeth Ficko-Blean acting as responsible curator for the CBM14 page. This CBM family continues to blur the lines betweeen CBMs and lectins and even type A , B and C CBMs. Find out more on these interesting chitin-binding multi-characteristic CBMs here.

1 December 2020: YANCEFP! (Yet Another New Carbohydrate Esterase Family Page, from our friends at WLU!) Following on a string of CE pages completed by students at Wilfred Laurier University (see CE3, CE4, CE7 and CE9), today Bobby Lamont finalized the Carbohydrate Esterase Family 2 under the guidance of Prof. Joel Weadge and Prof. Anthony Clarke. CE2 contains carbohydrate de-O-acetylases with diverse regiospecifcity, which use a catalytic dyad to perform hydrolysis. This family has a long and rich history of mechanistic and structural study, dating back to the last millennium, which you can learn much more about on Bobby's detailed page.

29 September 2020: Back to the future with beta-1,3-glucanases: The Glycoside Hydrolase Family 128 page was promoted to Curator Approved status by Mario Murakami today. GH128 was originally created following the discovery of this family by Yuichi Sakamoto and colleagues, who characterized the archetypal beta-1,3-glucanase from the shiitake mushroom. This year, a team led by Mario Murakami, including first-author Camila Santos, presented a sweeping first mechanistic and structural study of GH128. We're grateful to Camila and Mario for elaborating upon Yuichi's original CAZypedia page, which you can read here. You can also compare GH128 with other distinct beta-1,3-glucanase families covered in CAZypedia, e.g. GH17, GH81, GH148, and GH158.

CAZypedia is dedicated to the late Prof. Bruce Stone, whose enthusiasm to create a comprehensive encyclopedia of carbohydrate-active enzymes was essential in the genesis of this project.
