This entry represents the beta-alpha-beta-alpha-beta(2) domains common both to bacterial chorismate mutase and to members of the YjgF family. These proteins form trimers with a three-fold symmetry with three closely-packed beta-sheets.

Chorismate mutase (CM, ) is an enzyme of the aromatic amino acid biosynthetic pathway that catalyses the reaction at the branch point of the pathway leading to the three aromatic amino acids, phenylalanine, tryptophan and tyrosine (chorismic acid is the last common intermediate, and CM leads to the L-phenylalanine/L-tyrosine branch). It is part of the shikimate pathway, which is present only in bacteria, fungi and plants. The structure of chorismate mutase enzymes from Bacillus subtilis [PubMed10818343] and Thermus thermophilus have been solved and were shown to have a catalytic homotrimer, with the active sites being located at the subunit interfaces, where residues from two subunits contribute to each site.

The YjgF family is a large, widely distributed family of proteins of unknown biochemical function that are highly conserved among eubacteria, archaea and eukaryotes. Members include not only the conserved bacterial protein YjgF that displays a homotrimeric structure [PubMed10595546], but also the regulatory protein YabJ from B. subtilis that is required for adenine-mediated repression of purine biosynthetic genes [PubMed10557275], the yeast growth inhibitor YER057cp that appears to play a role in the regulation of metabolic pathways and cell differentiation [PubMed11442631], and the mammalian 14.5 kDa translational inhibitor protein L-PSP (liver perchloric acid-soluble protein) with endoribonucleolytic activity that directly affects mRNA translation and can induce disaggregation of the reticulocyte polysomes into 80 S ribosomes [PubMed10400702].

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 33 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 YjgF-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 33 hidden Markov models representing the YjgF-like superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
