Superfamily: Pseudouridine synthase

the active site is the most conserved structural region of the superfamily and is located between the subdomains
link to SUPERFAMILY database - Superfamily

Lineage:

  1. Root: scop
  2. Class: Alpha and beta proteins (a+b) [53931]
    Mainly antiparallel beta sheets (segregated alpha and beta regions)
  3. Fold: Pseudouridine synthase [100877]
    consists of two alpha+beta subdomains with some similarity to the ferredoxin-like fold
  4. Superfamily: Pseudouridine synthase [55120]
    the active site is the most conserved structural region of the superfamily and is located between the subdomains
