Abstract

Transport of molybdenum into bacteria involves a high-affinity ABC transporter system whose expression is controlled by a repressor protein called ModE. While molybdate transport is tightly coupled to utilization in some bacteria, other organisms have molybdenum storage proteins. One class of putative molybdate storage proteins is characterised by a sequence consisting of about 70 amino acids (Mop). A tandem repeat of Mop sequences also constitutes the molybdate binding domain of ModE.

The 7 kDa Mop protein from the methanol-utilizing anaerobe Sporomusa ovata occurs as highly symmetric hexamers binding eight oxyanions. Each peptide assumes an OB fold, which has previously also been observed in ModE. Each hexameric Mop molecule contains eight metal binding sites of two different types; all of them are only formed upon oligomer assembly, i.e., each binding site is located on the interface between two or three dimers [PubMed11080635].

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 15 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 MOP-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 15 hidden Markov models representing the MOP-like superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
