'''June 4, 2018:''' ''When two worlds collide.'' The [[CBM81]] family has an interesting binding mechanism, mixing characteristics of both [[Carbohydrate-binding_modules#Types|type A]] and [[Carbohydrate-binding_modules#Types|type B]] binding.  The binding is enthalpically driven to soluble ligands, so by definition this is a [[Carbohydrate-binding_modules#Types|type B]] interaction;  however, the CBM binding face resembles the flat face of [[Carbohydrate-binding_modules#Types|type A]] (crystalline-polysaccharide binding) CBMs.  '''[[User: Marcelo Liberato|Marcelo Liberato]]''' authored the [[CBM81]] page and '''[[User: Fabio Squina|Fabio Squina]]''' acted as responsible curator.  Find out more about the unusual family 81 CBMs '''[[CBM81|here]]'''.

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!
