Glycoside Hydrolase Family 168

Mechanism	Retaining (inferred) e
3D Structure Status	( β / α ) ₈ barrel
Note	Family created after the demonstration of the endo-1,3-fucanase activity of the FunA protein (AXE80_10060) of Wenyingzhuangia fucanilytica by Shen et al., Frontiers in Microbiology (2020). FunA also displayed a transglycosidase activity.
