'''2 July 2014:''' ''More on the alpha-amylase clan:'' We are pleased to report that '''[[User:Stefan Janecek|Stefan Janecek]]''' has made another key contribution to ''CAZypedia'' by completing the '''[[Glycoside Hydrolase Family 77]]''' page today.  '''[[GH77]]''' contains enzymes variously known as ''amylomaltases'', ''4-α-glucanotransferases'', or ''disproportionating enzymes'' (''D-enzymes'' in plants), which catalyze (1-4)-to-(1-4) transglycosylation of alpha-glucan chains and form part of the starch/glycogen debranching system. Together with [[GH13]] and [[GH70]], [[GH77]] constitutes [[Clan]] GH-H, a clan of alpha-glucan-specific enzymes united by a common (β/α)<sub>8</sub> catalytic domain fold.  [[User:Stefan Janecek|Stefan]] is the founder and main organiser of ''ALAMY'' - the international symposia on the alpha-amylase enzyme family -  and has been a key person in producing the [[GH13]], [[GH70]], [[GH77]] pages in ''CAZypedia''; we are especially grateful for his hard work and expertise!

'''2 May 2024:''' ''CBDs I to X... A major milestone!'' '''CBM families 1 to 10 are now complete!''' These are the old CBD (cellulose-binding domain) families, which used to have roman numerals as part of their nomenclature. A special thank you to all the authors and responsible curators who have contributed to this major milestone. Go have a peek at each of these old school families on their respective ''CAZypedia'' pages: '''[[CBM1]], [[CBM2]], [[CBM3]], [[CBM4]], [[CBM5]], [[CBM6]], [[CBM7]], [[CBM8]], [[CBM9]], and [[CBM10]]'''.

''"LysM" domains in CAZypedia:'' The cohort of [[Carbohydrate Binding Module Families]] covered in ''CAZypedia'' continues to grow with the completion of the '''[[Carbohydrate Binding Module Family 50]]''' by '''[[User:Takayuki Ohnuma|Takayuki Ohnuma]]''' and '''[[User:Toki Taira|Toki Taira]]'''. [[CBM50]] members are also known as LysM domains, which are found in a range of enzymes beyond glycoside hydrolases, including proteases, in which they are believed to facilitate targeting and degradation the bacterial cell wall.

'''14 May 2014:''' ''Two new CBM pages:'' We are pleased to report that '''[[User:Shinya Fushinobu|Shinya Fushinobu]]''' has produced and given [[Curator Approved]] status to two new [[CBM]] pages.  '''[[Carbohydrate Binding Module Family 28]]''' contains Type B CBMs that target non-crystalline beta-glucan chains, while '''[[Carbohydrate Binding Module Family 42]]''' members are Type C CBMs that bind terminal, non-reducing-end L-arabinofuranosyl residues, as found in xylans.  Both families are likely to play key role in potentiating biomass degradation by their host organisms, and are therefore relevant to related biotechnological applications.

'''[[CBM6]]''' was originally defined based on the observation of xylan binding, however the diversity of substrate specificities in this family has now grown to include diverse beta-glucans, chitin, and even the marine polysaccharide agarose; remarkably, some '''[[CBM6]]''' members also contain two distinct binding sites.  The '''[[CBM6]]''' page is ''CAZypedia's'' second [[Carbohydrate Binding Module Families|Carbohydrate Binding Module Family]] page, and we [[Carbohydrate_Binding_Module_Families#Under_construction|look forward]] to the further expansion of this section in the new year!

2 May 2024: CBDs I to X... A major milestone! CBM families 1 to 10 are now complete! These are the old CBD (cellulose-binding domain) families, which used to have roman numerals as part of their nomenclature. A special thank you to all the authors and responsible curators who have contributed to this major milestone. Go have a peek at each of these old school families on their respective CAZypedia pages: CBM1, CBM2, CBM3, CBM4, CBM5, CBM6, CBM7, CBM8, CBM9, and CBM10.

11 February 2024: A "BLAST" from the past, with a fresh update. Author Eduardo Moreno Prieto composed a new page on Glycoside Hydrolase Family 119,a family of bacterial amylases, which was Curator Approved by Stefan Janecek and Bernard Henrissat today. The first member of GH119 was characterized in 2006, and through sequence analysis with GH57 members, Janeček and Kuchtová predicted the active-site residues in 2012. Over a decade later, Eduardo, Bernard, and colleagues finally provided critical experimental support for these predictions. Learn more about this history, and especially the relationship between GH119 and GH57, in CAZypedia.

3 February 2024: A new family of beta-1,2-glucan-cyclizing enzymes. A page on the (currently) newest GH family, Glycoside Hydrolase Family 189, was completed today by Authors Tomoko Masaike, Masahiro Nakajima, and Nobukiyo Tanaka (Masahiro Nakajima is the Responsible Curator). GH189 is a family of bacterial transglycosylases that comprise a critical domain in cyclic beta-1,2-glucan synthase (CGS), because this domain is responsible for the final cyclization step during the biosynthesis of these key effector molecules. The discovery of GH189 builds on similarly exciting work by these authors and their colleagues on beta-1,2-glucan hydrolases in GH144 and GH162, which share a common protein fold with GH189, but have distinct mechansims. Check out the GH189, GH144, and GH162 pages to learn more about this breakthrough work on beta-1,2-glucan-active enzymes!
