Class a: All alpha proteins [46456] (290 folds) |
Fold a.102: alpha/alpha toroid [48207] (6 superfamilies) multihelical; up to seven alpha-hairpins are arranged in closed circular array; there may be sequence similarities between different superfamilies |
Superfamily a.102.4: Terpenoid cyclases/Protein prenyltransferases [48239] (5 families) |
a.102.4.1: Terpenoid cyclase N-terminal domain [48240] (3 proteins) incomplete toroid made of four hairpins automatically mapped to Pfam PF01397 |
a.102.4.2: Terpene synthases [48243] (3 proteins) consists of two toroid domains: one of six and one of five hairpins |
a.102.4.3: Protein prenyltransferases [48246] (3 proteins) |
a.102.4.4: Complement components [48251] (4 proteins) probably related to other families, but has no known enzymatic activity |
a.102.4.0: automated matches [227201] (1 protein) not a true family |
