This domain is found in tRNA-splicing endonuclease from the archaea Thermoplasma acidophilum (EndA), which is organised into two major domains, the N-terminal domain and the catalytic domain (Pfam:PF01974), with a linker region between them (this entry). This domain consists of an alpha-helix and three consecutive beta-strands [1].	Domain
