Abstract

The duplicated hybrid motif is a structural motif that is found in certain glucose-permease-like enzymes, and consists of a half-barrel beta-sheet of eight strands that is sandwiched with two 3-stranded beta-sheets. Enzymes displaying this motif include domain IIa of the glucose-specific permease from bacteria , which is part of the phosphoenolpyruvate:sugar phosphotransfer system (PTS), a bacterial and mycoplasma system responsible for the uptake of some sugars and their concomitant phosphorylation [PubMed9705652].

This structural motif is also found in peptidoglycan hydrolase LytM, a member of peptidase family M23, although it contains an extra N-terminal, non-conserved beta-sheet subdomain.

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 4 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 Duplicated hybrid motif 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 4 hidden Markov models representing the Duplicated hybrid motif superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
