30 Apr 2012: A new cellulase fold: On April 27, 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 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 α8 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.


09 Mar 2012: β-glucuronidases!: Hot on the heels of their recent seminal structural and biochemical characterization of a Glycoside Hydrolase Family 79 β-glucuronidase, Hitomi Ichinose and Satoshi Kaneko have just completed the GH79 page in CAZypedia. GH79 is currently a rather small family comprised of enzymes from bacteria, fungi, plants, and mammals, which remove glucuronic acid (GlcA) or 4-O-methyl glucuronic acid from a diversity of substrates, ranging from secondary metabolites to structural biomolecules such as proteoglycans and arabinogalactan proteins.

11 Jan 2012: New for the new year: CAZypedia is proud to report that our first new page of 2012, the Glycoside Hydrolase Family 99 page, has been completed by Spencer Williams and given Curator Approved status today. This page follows the recent publication of seminal structural and mechanistic analyses by a multi-investigator team including CAZypedia Curators Spencer Williams and Gideon Davies, which suggests that endo-mannosidases of this family may use an unusual mechanism involving a 1,2-anhydro-β-mannopyranose ("sugar epoxide") intermediate to effect the release of Glc1–3-1,3-α-Man oligosaccharides during N-glycan trimming. GH99 is a small, but nonetheless important family, whose members come from both higher eukaryotes, which employ these enzymes in protein-folding quality-control, and bacteria, which are likely to use their homologues for carbohydrate scavenging in niche enviroments such as the human gut.


Also in the news: Spencer altered us to the fact that CAZypedia has clocked one million page views sometime recently. We're not quite sure what to make of that, but it seems like a pretty neat achievement. What is really interesting is that we are starting to see some dynamics in which pages are accessed most: Newer pages, such as GH18 (completed Oct. 2010), are becoming more popular than the very first CAZypedia page, GH1 (completed May 2007). And, some of the Lexicon pages, including those on the Cellulosome and anomeric configuration are right up there in the list. If you like to keep score, here's a list of our most popular pages.
