July 3, 2018: Revenge of the Ruminococci.
Three CBM families containing characterized CBM members from Ruminococcal bacteria are now on-line in CAZypedia; two of these families contain uniquely Ruminococcal CBMs. Ana Luis
authored the pages (in one fell swoop) and Harry Gilbert
acted as responsible curator. Descriptions of families CBM75
can be found on their respective CAZypedia pages.
June 4, 2018: When two worlds collide. The CBM81 family has an interesting binding mechanism, mixing characteristics of both type A and type B CBMs. The binding is enthalpically driven to soluble ligands, so by definition this is a type B interaction; however, the CBM binding face resembles the flat face of type A (crystalline-polysaccharide binding) CBMs. Marcelo Liberato authored the CBM81 page and Fabio Squina acted as the Responsible Curator. Find out more about the unusual family 81 CBMs here.
25 May 2018: The almost exclusive expansin associated CBM63 family is on-line. An interesting function is described as a bacterial CBM63 targets expansin to biomechanical hotspots in the Arabidopsis cell wall, where cell wall loosening occurs. The page was authored by Will Chase and Daniel Cosgrove with Daniel Cosgrove acting as responsible curator. Learn more about this expansin family CBM here.
4 May 2018: CAZypedia's first non-LPMO Auxiliary Activity Family page! Today Responsible Curator Roland Ludwig approved Daniel Kracher's and his expansive Auxiliary Activity Family 3 page. AA3 comprises a number of FAD-dependent redox enzymes including cellobiose dehydrogenase, aryl alcohol oxidase/dehydrogenases, glucose oxidases and glucose dehydrogenases, pyranose dehydrogenase, alcohol oxidase, and pyranose oxidase across four subfamilies. Roland and Daniel have done a monumental job in succinctly capturing the diversity of this family, which you can read about here.
2 May 2018: The CBM65 page has been added to the CAZypedia fold. This is a small CAZy family with two currently characterized members from an anaerobic cellulolytic ruminal bacterium. The two CBM65 members bind various beta-glucans and play an important role in enhancing enzymatic activity on substrate. The page was authored by Ana Luis and Harry Gilbert acted as responsible curator. Learn more about this CBM family here.
1 March 2018: The shortest month of the year saw four CBM families reach Curator Approved status, including two early members. Harry Gilbert with input from Ed Bayer, who also acted as Responsible Curator, authored the cellulose-binding CBM3 page. Harry Gilbert and Claire Dumon both contributed to the xylan and glucan-binding CBM4 page. The xylan-binding CBM22 page was taken on by Harry Gilbert solo. Finally, the cellulose-binding CBM78 family was authored by Immacolata Venditto, with Harry Gilbert acting as Responsible Curator. Learn more about each of these families on their respective pages.
15 February 2018: More on pectin, and also arabinan: Jonathon Briggs recently completed the Glycoside Hydrolase Family 147 and Glycoside Hydrolase Family 146 pages, which are involved in the utilization of pectin and galactan, respectively, by human gut Bacteroidetes. Both pages were upgraded to Curator Approved status today by Responsible Curator Harry Gilbert. Learn more about these newly described families at GH146 and GH147.
13 February 2018: The intricacies of pectin deconstruction: Rhamnogalacturonan II (RGII) represents the most structurally complex plant cell wall polysaccharide currently known, the complete saccharification of which requires a battery of CAZymes. Under the guidance of Responsible Curator Harry Gilbert, four new GH pages related to RGII deconstruction were Curator Approved today. Special thanks go to Authors Ana Luis (GH106, GH139, and GH141) and Didier Ndeh (GH138) for their hard work in putting these pages together. Learn more about the individual, specific contributions of each of these families (three of which have been recently uncovered) to microbial RGII utilization on their respective pages.
