Homologous Superfamily

Polyribonucleotide nucleotidyltransferase, RNA-binding domain superfamily (IPR036456)

Short name: PNPase_PH_RNA-bd_sf

Overlapping entries


This superfamily represents an RNA-binding domain found in bacterial and organelle PNPases, but not in exosomes. It usually occurs in combination with PH domain 1 (IPR001247) and PH domain 2 (IPR015847), both of which are found in PNPases and exosomes. The core structure of the RNA-binding domain consists of a DNA/RNA-binding 3-helical bundle.
