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 See a page that's out-of-date and just needs a touch-up?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.

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.
