Glycoside Hydrolase Family 145

Activities in FamilyL-Rhα-α-1,4-GlcA α-L-rhamnohydrolase (EC 3.2.1.-)
Mechanism Retaining
3D Structure Statusseven-bladed β-propeller
Catalytic Nucleophile/BaseHis
NoteCreated after Munoz-Munoz et al., Proc. Natl. Acad. Sci. USA (2017) (PMID=28396425); these enzymes hydrolyze a-L-rhamnose residues linked to position 4 of a glucuronic acid using an unusual catalytic machinery comprising a histidine residue. The active site of these a-L-rhamnosidases is located on the opposite side of CAZymes with similar b-propeller folds. Surprisingly, the "normal" side of the b-propeller bears the highest residue conservation in the family and may well have another function. The latter is unknown but strong ressemblance to family PL25 suggests a polysaccharide lyase activity.
