Abstract

RmlC (dTDP (deoxythimodone diphosphates)-4-dehydrorhamnose 3,5-epimerase) is a dTDP-sugar isomerase enzyme involved in the synthesis of L-rhamnose, a saccharide required for the virulence of some pathogenic bacteria [PubMed10802738]. RmlC is a dimer, each monomer being formed from two beta-sheets arranged in a beta-sandwich, where the substrate-binding site is located between the two sheets of both monomers.

Other protein families contain domains that share this fold, including glucose-6-phosphate isomerase ; germin, a metal-binding protein with oxalate oxidase and superoxide dismutases activities [PubMed11062559]; auxin-binding protein [PubMed12065401]; seed storage protein 7S [PubMed11124907]; acireductone dioxygenase [PubMed12402029]; as well as three proteins that have metal-binding sites similar to that of germine, namely quercetin 2,3-dioxygenase [PubMed11839311], phosphomannose isomerase [PubMed8612079] and homogentisate dioxygenase [PubMed10876237], the last three sharing a 2-domain fold with storage protein 7s.

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 59 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 RmlC-like cupins 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 59 hidden Markov models representing the RmlC-like cupins superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
