Class b: All beta proteins [48724] (178 folds) |
Fold b.50: Acid proteases [50629] (1 superfamily) barrel, closed; n=6, S=10, complex topology |
Superfamily b.50.1: Acid proteases [50630] (4 families) |
b.50.1.1: Retroviral protease (retropepsin) [50631] (9 proteins) dimer of identical mono-domain chains, each containing (6,10) barrel |
b.50.1.2: Pepsin-like [50646] (11 proteins) duplication: consists of two similar barrel domains N-terminal: barrel, partly opened; n*=6, S*=10 |
b.50.1.3: LPG0085-like [159190] (1 protein) Pfam PF05618; DUF785; single-domain protein similar to one pepsin domain with the conserved catalytic Asp motif (not in a few archaeal members of this Pfam family) |
