Fold: Double-split beta-barrel

pseudobarrel; capped on both ends by alpha-helices

Lineage:

  1. Root: scop
  2. Class: All beta proteins [48724]
  3. Fold: Double-split beta-barrel [89446]
    pseudobarrel; capped on both ends by alpha-helices

Superfamilies:

  1. AbrB/MazE/MraZ-like [89447] (3)
    members of this superfamily are known or predicted to have DNA-binding function

    1. Kis/PemI addiction antidote [89448] (1) picpic
      forms intertwined homodimer
    2. AbrB N-terminal domain-like [54743] (2) picpic
      dimeric fold similar to MazE; the DNA-binding site is similar to the conserved surface site of MraZ
    3. Hypothetical protein MraZ [102020] (1) picpic
      duplication: contains two interlocking repeats of similar sequence arranged as subunits in the MazE homodimer
  2. AF2212/PG0164-like [141694] (2)
    six-stranded barrel, topologically similar to the Reductase/isomerase/elongation factor domain fold (scop_cf 50412)
    link to SUPERFAMILY database - Superfamily
    1. PG0164-like [141695] (1) picpic
      duplication: comprises two intertwinned beta(2)-alpha-beta structural repeats
    2. AF2212-like [159360] (1) picpic
      Pfam 01954; DUF104; intertwinned homodimer of beta(2)-loop-beta subunits; the capping helices are replaced with extended loops
