Superfamily Children

• Profilin (actin-binding protein) (55770)

  alpha-beta(2)-alpha-beta(5)-alpha
  Superfamily

• GAF domain-like (55781)

  alpha(2)-beta(3)-alpha-beta(3)-alpha; antiparallel beta-sheet: order 321654
  Superfamily

• PYP-like sensor domain (PAS domain) (55785)

  alpha-beta(2)-alpha(2)-beta(3)
  Superfamily

• Pheromone-binding domain of LuxR-like quorum-sensing transcription factors (75516)

  alpha(2)-beta(2)-alpha(2)-beta(3)-alpha; possibly related to the PAS domain
  Superfamily

• Sensory domain-like (103190)

  alpha(2)-beta(2)-alpha(2)-beta(3); possibly related to the PAS domain
  Superfamily

• SNARE-like (64356)

  beta(2)-alpha-beta(3)-alpha(2)
  Superfamily

• Roadblock/LC7 domain (103196)

  alpha-beta(2)-alpha-beta(3)-alpha; structurally most similar to the SNARE-like superfamily with a circular permutation of the terminal helices
  Superfamily

• YeeU-like (143737)

  beta(2)-alpha-beta(3); 2 layers, a/b; there is an oligomerization interface instead of the 'missing' helical layer
  Superfamily

• GlcG-like (143744)

  alpha-beta(2)-alpha(3)-beta(2)-alpha; similar to the Roadblock/LC7 domain
  Superfamily

• YNR034W-A-like (998036)
