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.

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.

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.
