    A PF01909   NTP_transf_2 Nucleotidyltransferase domain Family
    A PF10421   OAS1_C 2'-5'-oligoadenylate synthetase 1, domain 2, C-terminus Domain This is the largely alpha-helical, C-terminal half of 2'-5'-oligoadenylate synthetase 1, being described as domain 2 of the enzyme and homologous to a tandem ubiquitin repeat. It carries the region of enzymic activity between 320 and 344 at the extreme C-terminal end [1]. Oligoadenylate synthetases are antiviral enzymes that counteract vial attack by degrading viral RNA. The enzyme uses ATP in 2'-specific nucleotidyl transfer reactions to synthesise 2'.5'-oligoadenylates, which activate latent ribonuclease, resulting in degradation of viral RNA and inhibition of virus replication [2]. This domain is often associated with NTP_transf_2 Pfam:PF01909. Source: Pfam
