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

Alignments of sequences to 2 models
in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical
are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.

|
Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.
|
There are 2 hidden Markov models representing the Polynucleotide phosphorylase/guanosine pentaphosphate synthase (PNPase/GPSI), domain 3 superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
