GH105 enzymes are a class of unsaturated glucuronyl/galacturonyl hydrolases found mainly in bacteria, but a few fungial and a handful of archaeal enzymes have also been annotated ''Cantarel2009''. Much like the glycoside hydrolase family 88, enzymes from GH105 perform hydrolysis via a hydration of the double bond between the C-4 and C-5 carbons of the terminal monosaccharide of their substrates ''Munoz-Munoz2017''. Enzymes from GH105 have been organized into three subgroups: unsaturated rhamnogalacturonidases, d-4,5-unsaturated β-glucuronyl hydrolases, and d-4,5-unsaturated α-galacturonidases. The unifying feature shared between these substrates is the presence of the non-reducing monosaccharide 4-deoxy-L-threo-hex-4-enopyranuronosyl that binds at the -1 active site of the enzymes, and is linked to the +1 sugar via its anomeric C-1 carbon. The 4-deoxy-L-threo-hex-4-enopyranuronosyl saccharide is defined as ΔGal or ΔGlc depending on whether it assumes an α- or β- configuration, respectively. In degradable substrates, the sugar present at the +1 position can be linked via its C-2, C-4, or C-6 carbon, given the substrate preference of individual enzymes

Substrate specificities

GH105 enzymes are a class of unsaturated glucuronyl/galacturonyl hydrolases found mainly in bacteria, but a few fungial and a handful of archaeal enzymes have also been annotated Cantarel2009. Much like the glycoside hydrolase family 88, enzymes from GH105 perform hydrolysis via a hydration of the double bond between the C-4 and C-5 carbons of the terminal monosaccharide of their substrates Munoz-Munoz2017. Enzymes from GH105 have been organized into three subgroups: unsaturated rhamnogalacturonidases, d-4,5-unsaturated β-glucuronyl hydrolases, and d-4,5-unsaturated α-galacturonidases. The unifying feature shared between these substrates is the presence of the non-reducing monosaccharide 4-deoxy-L-threo-hex-4-enopyranuronosyl that binds at the -1 active site of the enzymes, and is linked to the +1 sugar via its anomeric C-1 carbon. The 4-deoxy-L-threo-hex-4-enopyranuronosyl saccharide is defined as ΔGal or ΔGlc depending on whether it assumes an α- or β- configuration, respectively. In degradable substrates, the sugar present at the +1 position can be linked via its C-2, C-4, or C-6 carbon, given the substrate preference of individual enzymes
