This family has structural similarity to an endo-1,3-1,4-beta glucanase belonging to glycoside hydrolase family 16. A member containing this domain, BT2157 from B. thetaiotaomicron [1], hydrolyses 3-ketotrehalose during trehalose degradation that proceeds through a 3-keto-glycoside intermediate. Other members containing this domain are involved in disaccharide catabolism with 3-ketoglycoside intermediates [1].	Domain
