Rhamnogalacturan_acetylesterase_like subgroup of SGNH-hydrolases. Rhamnogalacturan acetylesterase removes acetyl esters from rhamnogalacturonan substrates, and renders them susceptible to degradation by rhamnogalacturonases. Rhamnogalacturonans are highly branched regions in pectic polysaccharides, consisting of repeating -(1,2)-L-Rha-(1,4)-D-GalUA disaccharide units, with many rhamnose residues substituted by neutral oligosaccharides such as arabinans, galactans and arabinogalactans. Extracellular enzymes participating in the degradation of plant cell wall polymers, such as Rhamnogalacturonan acetylesterase, would typically be found in saprophytic and plant pathogenic fungi and bacteria.

Carbohydrate Binding Module family 35 (CBM35), pectate lyase-like; appended mainly to enzymes that bind mannan (Man), xylan, glucuronic acid (GlcA) and possibly glucans. This family includes carbohydrate binding module family 35 (CBM35) domains that are non-catalytic carbohydrate binding domains that are appended mainly to enzymes that bind mannan (Man), xylan, glucuronic acid (GlcA) and possibly glucans. Included in this family are CBM35s of pectate lyases, including pectate lyase 10A from Cellvibrio japonicas, these enzymes release delta-4,5-anhydrogalaturonic acid (delta4,5-GalA) from pectin, thus identifying a signature molecule for plant cell wall degradation. CBM35s are unique in that they display conserved specificity through extensive sequence similarity but divergent function through their appended catalytic modules. They are known to bind alpha-D-galactose (Gal), mannan (Man), xylan, glucuronic acid (GlcA), a beta-polymer of mannose, and possibly glucans, forming four subfamilies based on general ligand specificities (galacto, urono, manno, and gluco configurations). In contrast to most CBMs that are generally rigid proteins, CBM35 undergoes significant conformational change upon ligand binding. Some CBM35s bind their ligands in a calcium-dependent manner, especially those binding uronic acids.
