In silico identification of catalytic residues and domain fold of the family GH119 sharing the catalytic machinery with the α-amylase family GH57

► The GH119 family is predicted to adopt a (β/α)7-barrel fold. ► Conserved sequence regions of the family GH57 are recognised in GH119. ► The GH119 family shares catalytic machinery with the family GH57. ► The families GH57 and GH119 may create a novel CAZy GH clan.
