Structural Classification of Proteins
home mail help root up expand collapse

Fold: PurS-like

consists of two alpha+beta subdomains with some similarity to the ferredoxin-like fold

Lineage:

  1. Root: scop
  2. Class: Alpha and beta proteins (a+b) [53931]
    Mainly antiparallel beta sheets (segregated alpha and beta regions)
  3. Fold: PurS-like [109622]
    consists of two alpha+beta subdomains with some similarity to the ferredoxin-like fold

Superfamilies:

  1. PurS-like [82697] (2)
    segment-swapped dimer: the swapped segment is made of the first helix and second strand; a single long strand is formed by strands 2 and 3 of each subunit
