| − | '''09 May 2011:''' ''It's a big news day here at CAZypedia.'' We are proud to announce that three distinct glycoside hydrolase family pages have been [[Curator Approved]] today: | + | '''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 '''[[Carbohydrate-binding_modules#Blurred Lines: CBMs, Lectins and Outliers|lectin-like CBM family]]'''. Its first characterized members were lectins, including the B chain from the highly toxic [https://en.wikipedia.org/wiki/Ricin ricin] toxin from ''Ricinus communis''. This spine tingling read was authored by '''[[User:Scott Mazurkewich|Scott Mazurkewich]]''' and '''[[User:Lauren McKee|Lauren McKee]]''' who also acted as responsible curator. ''Come and visit the scariest of ''CAZypedia'' CBM pages, '''[[CBM13|here!]]'''... if you dare...'' |
| − | * '''[[Glycoside Hydrolase Family 74]]''' (written by '''[[User:Katsuro Yaoi|Katsuro Yaoi]]''' and '''[[User:Takuya Ishida|Takuya Ishida]]''', and curated by '''[[User:Katsuro Yaoi|Katsuro Yaoi]]''') is a family predominantly comprised of endo-glucanases that are specific for the plant polysaccharide xyloglucan (true xyloglucanases).

| − | * '''[[Glycoside Hydrolase Family 95]]''' (written and curated by '''[[User:Takane Katayama|Takane Katayama]]''') is a family of 1,2-α-L-fucosidases, members of which cleave human milk oligosaccharides, blood group glycoconjugates, and/or xyloglucan oligosaccharides.

| − | * '''[[Glycoside Hydrolase Family 117]]''' (written by '''[[User:Etienne Rebuffet|Etienne Rebuffet]]''' and curated by '''[[User:Mirjam Czjzek|Mirjam Czjzek]]''') is a small, newly created family of α-1,3-L-(3,6-anhydro)-galactosidases (neoagarobiose hydrolases), which catalyze the final step in the degradation of agars from red macroalgae in the marine environment.

| − | ''We would like to express our sincere thanks to our Japanese and French colleagues for these important contributions to CAZypedia.'' Links to these families will be included in the next public update of the [http://www.cazy.org/ CAZy database] (expected soon!). | |

| − | ''Special thanks also go to '''[[User:Etienne Rebuffet|Etienne]]''' for updating the '''[[Glycoside Hydrolase Family 82]]''' page,'' including a very cool animated image that highlights enzyme domain movement during substrate binding. | |

| − | '''28 April 2011:''' ''More on α-glucoside cleavage:'' [[Author]] and [[Responsible Curator]] '''[[User:Takashi Tonozuka|Takashi Tonozuka]]''' recently completed the '''[[Glycoside Hydrolase Family 63]]''' page, which has been updated to [[Curator Approved]] status today. '''[[GH63]]''' is especially notable as it contains the eukaryotic "processing α-glucosidase I enzymes," which are essential for N-glycan trimming during glycoprotein maturation. '''[[User:Takashi Tonozuka|Takashi Tonozuka's]]''' group has done seminal structural elucidation work in this family, and we very much appreciate his contribution to ''CAZypedia'', especially during these tough times in Japan. | + | '''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 '''[[User:Daichi Ito|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 '''[[CBM91|here]]'''.'' |

| − | '''21 March 2011:''' ''A new page on the equinox (as we thaw-out and welcome the sun back to the Baltic region):'' [[Responsible Curator]] '''[[User:Anna Kulminskaya|Anna Kulminskaya]]''' today approved the '''[[Glycoside Hydrolase Family 35]]''' page, which was written by '''[[User:Anna Kulminskaya|Anna]]''', with input on the 3-D structure section from '''[[User:Mirko Maksimainen|Mirko Maksimainen]]''' and '''[[User:Juha Rouvinen|Juha Rouvinen]]'''. '''[[GH35]]''' is a family of β-galactosidases from diverse organisms that display a range of bond specificities. Only very few tertiary structures have been solved in this family, to which the Russian and Finnish groups have made seminal contributions.

| − | '''28 February 2011:''' ''Hexosaminidases!:'' The '''[[Glycoside Hydrolase Family 20]]''' and '''[[Glycoside Hydrolase Family 84]]''' pages, which were completed last week by [[Author]] '''[[User:Ian Greig|Ian Greig]]''' and approved by [[Responsible Curator]] '''[[User:David Vocadlo|David Vocadlo]]''', have today been cross-linked from the [http://www.cazy.org CAZy database] ''(look out for the next public release)''. [[GH20]] is of significant medical relevance, as it contains the human enzymes HexA and HexB, deficiencies of which case Tay-Sachs disease and Sandhoff diseases, respectively. [[GH84]] is similarly important in the context of cell and organism biology, as this family contains human OGA (HexC, MGEA5, ''O''-GlcNAcase), a nuclear and cytoplasmic enzyme that is responsible for dynamic modulation of β-linked ''O''-GlcNAc residues linked to serine and threonine residues. ''O''-GlcNAc'ylation of specific protein residues has in some cases been found to be reciprocal to phosphorylation and, accordingly, has implicated ''O''-GlcNAc in diverse cellular processes and disease states.

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.
