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 See a page that's out-of-date and just needs a touch-up?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

3 November 2016: New PDB links-out: For 3-D visualization of exemplar CAZymes and CBMs, we're trying a switch from Proteopedia to the NGL viewer implementation at the RCSB Protein Data Bank. We've made this switch site-wide across CAZypedia, and would like to hear any feedback you might have. Here's an example for direct comparison: The seminal bacterial cellulose synthase complex in the JMol viewer at Proteopedia (including wiki page) and in the NGL viewer at the PDB (other info available via the page tabs).
30 October 2016: Another X-module comes to light: Today Spencer Williams completed the Glycoside Hydrolase Family 135 page, which describes the genesis of a new CAZy family from a small group of modules formerly known as "X307" in the CAZyModO classification. The single biochemically and structurally characterized GH135 member hydrolyzes the unique fungal exo-polysaccharide galactosaminogalactan, with crystallographic evidence suggesting that the enzyme acts as a alpha-galactosaminidase. However, a number of key enzymological questions about this new family remain outstanding, and we look forward to future work in this direction of the CAZyme landscape.
3 September 2016: Galactosaminoglycan degradation: Spencer Williams has just completed a short entry on Glycoside Hydrolase Family 114, a small family of bacterial and fungal sequences currently represented by a single characterized endo-alpha-1,4-polygalactosaminidase. alpha-1,4-Polygalactosamine, also known as galactosaminoglycan, is produced as a secreted polysaccharide by select fungi, including Aspergilli.
27 February 2016: The sweet side of sulfur: Author Spencer Williams has updated the Glycoside Hydrolase Family 31 page to reflect the recent discovery of the first dedicated sulfoquinovosidases (SQases), previously ‘hidden’ within this family. SQases cleave α-glycosides of sulfoquinovose (6-sulfoglucose), which represent a significant reservoir of organosulfur in the biosphere. See the GH31 page to discover more of the hidden charms of this family.
