Class c: Alpha and beta proteins (a/b) [51349] (134 folds) |
Fold c.1: TIM beta/alpha-barrel [51350] (32 superfamilies) contains parallel beta-sheet barrel, closed; n=8, S=8; strand order 12345678 the first seven superfamilies have similar phosphate-binding sites |
Superfamily c.1.8: (Trans)glycosidases [51445] (13 families) |
Family c.1.8.1: Amylase, catalytic domain [51446] (24 proteins) members of the family may contain various insert subdomains in alpha-amylases and closer relatives this domain is usually followed by a common all-beta domain |
Protein A4 beta-galactosidase [82246] (1 species) the catalytic domain is very similar to that of the bacterial beta-amylase; but contains a typical alpha-amylase extra domain |
