CAZypedia needs your help! We have many unassigned GH, PL, CE, AA, GT, and CBM pages in need of Authors and Responsible Curators.
Scientists at all career stages, including students, are welcome to contribute to CAZypedia. Read more here, and in the 10th anniversary article in Glycobiology.

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.
2 July 2014: More on the alpha-amylase clan: We are pleased to report that Stefan Janecek has made another key contribution to CAZypedia by completing the Glycoside Hydrolase Family 77 page today. GH77 contains enzymes variously known as amylomaltases, 4-α-glucanotransferases, or disproportionating enzymes (D-enzymes in plants), which catalyze (1-4)-to-(1-4) transglycosylation of alpha-glucan chains and form part of the starch/glycogen debranching system. Together with GH13 and GH70, GH77 constitutes Clan GH-H, a clan of alpha-glucan-specific enzymes united by a common (β/α)8 catalytic domain fold. Stefan is the founder and main organiser of ALAMY - the international symposia on the alpha-amylase enzyme family - and has been a key person in producing the GH13, GH70, GH77 pages in CAZypedia; we are especially grateful for all his hard work and expertise!
23 June 2014: "LysM" domains in CAZypedia: The cohort of Carbohydrate Binding Module Families covered in CAZypedia continues to grow with the completion of the Carbohydrate Binding Module Family 50 by Takayuki Ohnuma and Toki Taira. CBM50 members are also known as LysM domains, which are found in a range of enzymes beyond glycoside hydrolases, including proteases, in which they are believed to facilitate targeting and degradation the bacterial cell wall.
