Chains Pfam Accession Pfam Identifier Pfam Description Type Source
A PF01909 NTP_transf_2 Nucleotidyltransferase domain Family
A PF04926 PAP_RNA-bind Poly(A) polymerase predicted RNA binding domain Domain Based on its similarity structurally to the RNA recognition motif this domain is thought to be RNA binding [1]. PFAM PF04926
A PF04928 PAP_central Poly(A) polymerase central domain Domain The central domain of Poly(A) polymerase shares structural similarity with the allosteric activity domain of ribonucleotide reductase R1, which comprises a four-helix bundle and a three-stranded mixed beta- sheet. Even though the two enzymes bind ATP, the ATP-recognition motifs are different. PFAM PF04928
