corresponding fold description |
| d.153.1 | N-terminal nucleophile aminohydrolases (Ntn hydrolases) N-terminal residue provides two catalytic groups, nucleophile and proton donor ! | Ntn hydrolase-like 4 layers: alpha/beta/beta/alpha; has an unusual sheet-to-sheet packing |
| d.153.2 | Archaeal IMP cyclohydrolase PurO has a putative active site in the same topological location as the Ntn hydrolase but lacks the N-terminal nucleophile ! | Ntn hydrolase-like 4 layers: alpha/beta/beta/alpha; has an unusual sheet-to-sheet packing |
| d.17.4 | NTF2-like has a beta-alpha(2)-beta insertion after the main helix ! | Cystatin-like Core: alpha-beta(4); helix packs against coiled antiparallel beta-sheet |
| d.96.2 | ApbE-like duplication: contains two differently decorated beta(2)-alpha(2)-beta(2) subdomains, similar to other T-fold domains; probably does not form the tunnel-shaped oligomers ! | T-fold beta(2)-alpha(2)-beta(2); 2 layers: alpha/beta; antiparallel sheet 1234 ! tunnel-shaped: its known members form wide oligomeric barrels different sizes |
| b.2.6 | Cytochrome f, large domain | Common fold of diphtheria toxin/transcription factors/cytochrome f sandwich; 9 strands in 2 sheet; greek-key; subclass of immunoglobin-like fold |
| d.219.1 | PP2C-like contain binuclear metal (Mn) centre ! | PP2C-like 4 layers: alpha/beta/beta/alpha; antiparallel beta sheets |
| d.338.1 | Oxysterol-binding protein-like | Oxysterol-binding protein-like core: large meander beta-sheet of 12 strands wrapped around the N-terminal (distorted) alpha-hairpin; some similarity to transmembrane beta-barrel proteins |
| e.66.1 | Api92-like | Api92-like 2 domains; d1: [alpha+beta with similarity to ferredoxin-like fold]; d2: [6 helices, bundle, one buried central helix], inserted into d1 |
