Attention CAZymologists: Registration for CBM11 - The 11th Carbohydrate Bioengineering Meeting (Helsinki, 10-13 May 2015) - is now open!
CAZypedia maintains a history of the CBMs, including links to previous conference proceedings.
Also: Applications are now being accepted to attend the 2015 GRC on Cellulosomes, Cellulases & Other Carbohydrate Modifying Enzymes.

Welcome to CAZypedia!
The Encyclopedia of Carbohydrate-Active Enzymes.

Purpose

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."

Content

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

19 January 2015: Still in the high 70's today: Zui Fujimoto brought the Glycoside Hydrolase Family 78 page up to Curator Approved status today, making it CAZypedia's 97th approved GH page. GH78 is a family of archaeal, bacterial, and fungal alpha-L-rhamnosidases that cleave diverse flavonoid glycosides, polysaccharides, glycoproteins, and glycolipids from plants. Read more on these ecologically relevant enzymes here.

7 January 2015: Love your guts: CAZypedia is ringing in the new year with a new Glycoside Hydrolase Family 76 page by Spencer Williams. GH76 contains endo-acting α-mannanases, including members from the human gut bacterium Bacteroides thetaiotaomicron that enable us to degrade yeast mannans in our diet. A very recent publication in Nature, notably involving CAZypedia contributors Michael Suits, Al Boraston, Spencer Williams, Gideon Davies, Wade Abbott, and Harry Gilbert, has recently shed new light on the structure, mechanism, and biological function of these enzymes. Read more here!


11 September 2014: Another PL family done: Today, Richard McLean and Wade Abbott finished the Polysaccharide Lyase Family 22 page, bringing the number of Curator Approved PL pages in CAZypedia to a total of 5 (of 23). PL22 is a family of bacterial (and a handful of archeal) oligogalacturonide lyases (OGLs), archetypal members of which are highly specific for digalacturonate and Δ4,5-unsaturated digalacturonate i.e., they do not cleave polymeric α-(1,4)-linked galacturonan, a component of pectin. Wade performed a seminal crystallographic analysis of PL22, and he and Richard have produced a lucid distillation of the mechanism of catalysis in this family. Read more here!


9 September 2014: 2-for-1 Back to School Special: With the start of the new academic year, we are happy to report that two new Polysaccharide Lyase Family pages have recently been completed and given Curator Approved status. In August, Naotake Konno and Shinya Fushinobu produced the Polysaccharide Lyase Family 20 page, which describes this small (currently, 18 member) group of bacterial and fungal beta-(1-4)-glucuronan-cleaving enzymes. And, on the 7th of this month, Sine Larsen and Leila LoLeggio composed the Polysaccharide Lyase Family 4 page. Currently, PL4 is only known to contain rhamnogalacturonan lyases involved in pectin degradation, notably including many plant sequences in addition to bacterial and fungal members. We thank these Authors and Responsible Curators for their contributions and encourage our readers to check out these new pages.
