EC 4.3.2.4 is Orphan !
Common name :Purine imidazole-ring cyclase

Systematic name :DNA-4,6-diamino-5-formamidopyrimidine C(8)-N(9)-lyase (cyclizing; DNA-adenine-forming)

Other names :DNA-4,6-diamino-5-formamidopyrimidine 8-C,9-N-lyase (cyclizing)
DNA-4,6-diamino-5-formamidopyrimidine 8-C,9-N-lyase (cyclizing
DNA-adenine-forming)
Comments :Also acts on 2,6-diamino-5-formamido-3,4-dihydro-4-oxopyrimidine residues. Brings about the reclosure of the imidazole rings of purine residues damaged by gamma-rays.
