Abstract

This entry represents an alpha/beta domain consisting of alternating beta-strands and alpha helices in two layer. This domain is found in RNA 3'-terminal phosphate cyclase (RPTC), where it occurs as a duplication of three repeats of this fold packed together around a pseudo three-fold axis [PubMed10673421]. RNA cyclases are a family of RNA-modifying enzymes that catalyse the ATP-dependent conversion of the 3'-phosphate to the 2',3'-cyclic phosphodiester at the end of RNA. These cyclases contain an insert alpha/beta domain with a thioredoxin topology .

This domain is also found in enolpyruvate transferase, where it occurs as a duplication of six repeats of this fold organised into two RPTC-like domains [PubMed9485407, PubMed15995357]. Enolpyruvate transferase is the first enzyme in bacterial peptidoglycan biosynthesis, catalysing the transfer of enolpyruvate from phosphoenolpyruvate to UDP-N-acetyl-glucosamine.

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


Alignments of sequences to 5 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.


Browse and view proteins in genomes which have different domain combinations including a EPT/RTPC-like domain.


Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 5 hidden Markov models representing the EPT/RTPC-like superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
