An Unusual His/Asp Dyad Operates Catalysis in Agar-Degrading Glycosidases
{{output}}
Agarose motifs, found in agars present in the cell walls of red algae, consist of alternating units of d-galactose (G) and α-3,6-anhydro-l-galactose (LA). Glycoside hydrolases from family 117 (GH117) cleave the terminal α-1,3-glycosidic bonds, releasing LA u... ...
