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."


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 (e.g. Polysaccharide Lyases and Glycosyltransferases), 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). 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.

Latest news

6 February 2014: Our second LPMO page: Glyn Hemsworth and Gideon Davies have just completed the Auxiliary Activity Family 11 page. AA11 is a very recently discovered family of copper-dependent, lytic polysaccharide mono-oxygenases (LPMO), whose defining member catalyzes the oxidative cleavage of chitin. The LPMO field is particularly exciting and rapidly evolving, and we are proud to present the AA11 page in CAZypedia so closely after the initial report on this family.

17 January 2014: More on CBMs: The Carbohydrate Binding Module Family 41 page was upgraded to Curator Approved status today by Alicia Lammerts van Bueren and Al Boraston. CBM41 is a family of alpha-glucan-binding modules, which are primarily associated with the pullulanases and debranching enzymes of Glycoside Hydrolase Family 13. Find out more here...!

6 January 2014: A new year, a new CBM page! The Carbohydrate Binding Module Family 6 page was completed and given Curator Approved status today by Author and Curator Mirjam Czjzek. CBM6 was originally defined based on the observation of xylan binding, however the diversity of substrate specificities in this family has now grown to include diverse beta-glucans, chitin, and even the marine polysaccharide agarose; remarkably, some CBM6 members also contain two distinct binding sites. The CBM6 page is CAZypedia's second Carbohydrate Binding Module Family page, and we look forward to the further expansion of this section in the new year!

18 December 2013: A new mannanase page: Today, Rohan Williams and Spencer Williams completed the Glycoside Hydrolase Family 113 page. GH113 is currently a very small family (120 members) with only one characterized member, the Alicyclobacillus acidocaldarius beta(1-4)-mannanase. The seminal crystal structure of this enzyme revealed GH113 to be a member of Clan GH-A. A recent publication from the Williams team and collaborators illuminated further details of the GH113 and GH26 transition states using designed inhibitor-enzyme complexes. Read more about this emerging family here!

New for fall 2013: The CAZy database now presents enzyme ligands! See any family's "Structure" page for examples.

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.
