| − | '''14 February 2020:''' ''A rose by any other name would smell as sweet.'' The human gut bacterium ''Roseburia intestinalis'' provides a curator approved [[Carbohydrate Binding Module Family 86]] page as a special Valentine Day's gift. [[CBM86]] members are structurally located at the N-termini of [[GH10]] xylanase polypeptides. ''Roseburia intestinalis'' certainly enjoys the sugary xylans it encounters in the dietary tract as a carbon source and likely uses the [[CBM86]] modules to enhance xylan capture through improved xylan affinity for the xylanase enzymes. The [[CBM86]] page was written in record time by '''[[User:Maria Louise Leth|Maria Louise Leth]]''' with '''[[User:Maher Abou Hachem|Maher Abou Hachem]]''' acting as responsible curator. Read more on the 'rosy' xylan-binding [[CBM86]] family [[CBM86|here]]. | + | '''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...'' |

| − | '''16 December 2019:''' ''Closing the year with marine CAZymes:'' The '''[[Glycoside Hydrolase Family 107]]''' page, which describes a family of endo-1,4-fucanases, was finalized today by [[Author]] '''[[User:David Teze|David Teze]]''' and [[Responsible Curator]] '''[[User:Al Boraston|Alisdair Boraston]]'''. The characterized enzymes of this family hydrolyze the marine polysaccharides known as fucoidans (sulfated fucans). First identified by the Roscoff group in 2006 (see ''e.g.'' [[User:Gurvan Michel|Gurvan Michel]] and [[User:Mirjam Czjzek|Mirjam Czjzek]]), recent collaborative work by the [[User:Steve Withers|Withers]] and [[User:Al Boraston|Boraston]] groups has resolved the structure and mechanism of '''[[GH107]]'''. Of particular note, crystallography of two '''[[GH107]]''' members has revealed similarity with [[GH29]] members, which together now form the new [[Clan]] GH-R. ''See the '''[[GH107]]''' page for the details from the seminal publications on this family!'' | |

| − | '''Friday the 13th of December 2019:''' ''A spooky Christmas gift:'' The bacterial [[CBM71]] family is a new addition to [[Carbohydrate Binding Module Families|CAZypedia CBM]] just in time for Christmas! The CAZypedia CBM page describes the characterization of two lactose- and lacNAc- binding Pneumococcal [[CBM71]] members. The page was authored by '''[[User:Ben Pluvinage|Ben Pluvinage]]''' with '''[[User:Al Boraston|Alisdair Boraston]]''' acting as responsible curator. ''Find out more on the [[CBM71]] family [[CBM71|here]]!'' | + | '''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]]'''.'' |

| − | '''3 November 2019:''' ''Xylan-cleaving LPMOs:'' Today, [[Responsible Curator]] '''[[User:Jean-Guy Berrin|Jean-Guy Berrin]]''' approved the '''[[Auxiliary Activity Family 14]]''' page [[Author|authored]] by '''[[User:Marie Couturier|Marie Couturier]]''', which describes one of the newer families of lytic polysaccharide monooxygenases (LPMOs) described in the CAZy database. '''[[AA14]]''' was first described in 2018 by '''[[User:Marie Couturier|Marie]]''', '''[[User:Jean-Guy Berrin|Jean-Guy]]''', and their co-workers. Notably, they showed that the founding members of this family were specific for the plant cell wall matrix glycan, xylan, which contrasts other families of LPMOs that are predominantly cellulose- or chitin-active. ''Check out the '''[[AA14]]''' page for more details!''

| − | '''24 October 2019:''' ''A tale of an amoebal CBM:'' The '''[[Carbohydrate Binding Module Family 55]]''' page discussing the pathogenically interesting chitin-binding '''[[CBM55]]''' family has been flipped to curator approved. The '''[[CBM55]]''' family was first identified from ''Entamoeba histolytica'', a protist that causes dysentery and liver abscesses. The page was authored by '''[[User:John Samuelson|John Samuelson]]''' with '''[[User:Elizabeth Ficko-Blean|Elizabeth Ficko-Blean]]''' acting as responsible curator. ''Read more on this amoebal CBM family on the '''[[CBM55]]''' page.''

| − | '''15 October 2019:''' ''A new debut for beta(1-2):'' The '''[[Glycoside Hydrolase Family 144]]''' page, which describes the β-1,2-glucanases in this family, was completed by [[Author]] '''[[User:Koichi Abe|Koichi Abe]]''' and [[Responsible Curator]] '''[[User:Masahiro Nakajima|Masahiro Nakajima]]''' today. '''[[GH144]]''' was founded in 2017 based on a seminal publication by '''[[User:Koichi Abe|Koichi Abe]]''', '''[[User:Masahiro Nakajima|Masahiro Nakajima]]''', and their colleagues. Interestingly, '''[[GH144]]''' contains both ''endo''-β-1,2-glucanases ([{{EClink}}3.2.1.71 EC 3.2.1.71]), as well as ''exo''-acting enzymes that release sophorose (Glc-β(1,2)-Glc) from the nonreducing end of β(1,2)-glucan chains ("sophorohydrolases", analogous to the more well-known "cellobiohydrolases") ''Learn more about these enzymes, whose protein structure is distantly related to that of the fungal β-1,2-glucanases from [[GH162]], on the '''[[GH144]]''' page!''

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.
