CAZypedia celebrates the life of Senior Curator Emeritus Harry Gilbert, a true giant in the field, who passed away in September 2025.

CAZypedia needs your help!

We have many unassigned pages in need of Authors and Responsible Curators. See a page that's out-of-date and just needs a touch-up? - You are also welcome to become a CAZypedian. Here's how.
Scientists at all career stages, including students, are welcome to contribute.

'''30 Apr 2012:''' ''A new cellulase fold:'' On April 27, '''[[User:Harry Gilbert|Harry Gilbert]]''' completed the '''[[Glycoside Hydrolase Family 124]]''' page here on ''CAZypedia.'' '''[[GH124]]''' is a comparatively new, but tiny, family in the CAZy classification.  This family is currently comprised of only three members (2 near-identical sequences from 2 ''Clostridium'' spp. and 1 from ''Ruminococcus albus''), but was defined as a GH family based on the demonstration of cellulase activity in one of the Clostridial members.  Remarkably, this enzyme was also shown to have a ''α''<sub>8</sub> superhelical fold, which has not been previously observed in cellulases, but is rather found in diverse lysozymes and lytic transglycosylases of [[GH23]] active on bacterial cell wall peptidoglycan.

23 January 2026: An oldie, but a goodie: As our first page of the new year, the Glycoside Hydrolase Family 71 page, written by Antonielle Vieira Monclaro, was Curator Approved by Johan Larsbrink today. GH71 is a family of mostly fungal alpha-1,3-glucanases that was established and subjected to mechanistic characterization in the early 2000s. More recently in 2025, the Yano and Larsbrink groups independently presented the first crystal structures of GH71 members (from Schizosaccharomyces and Aspergillus, respectively). Antonielle wrote an excellent overview of GH71, which you should definitely check out here.

8 December 2025: Just in time for the holidays: The Glycosyltransferase Family 138 page by Author Wei Peng and Responsible Curator Kim Orth was Curator Approved today. GT138 is small family of plant-associated bacterial members. The archetype from Pseudomonas syringae, AvrB, is a rhamnosyl transferase that glycosylates the plant host protein RIN4 to effect programmed cell death (hypersensitive response). Also notable, AvrB has an unusual protein fold among glycosyltransferases, based upon a "Fido" domain. GT138 represents one of a small, but hopefully growing, number of GT pages in CAZypedia, whose unique features you should read more about here.

31 October 2025: A spooktacular addition to the CAZypedia family! Come and say 'Boo!' to the frighteningly well written CBM13 CAZypedia page. The CBM13 family is a lectin-like CBM family. Its first characterized members were lectins, including the B chain from the highly toxic ricin toxin from Ricinus communis. This spine tingling read was authored by Scott Mazurkewich and Lauren McKee who also acted as responsible curator. Come and visit the scariest of CAZypedia CBM pages, here!... if you dare...

29 July 2025: CBM91 is in the news! The xylan binding CBM91 family CAZypedia page is up and running. Appended to mainly GH43 xylanases this CBM91 family drives interaction with substrate. The CBM91 page was authored by Daichi Ito who also discovered the initial xylan-binding function which resulted in the creation of the CBM91 CAZy family. Read up on this industrially interesting CBM91 family here.
