Abstract

This entry represents the major region of PLP-dependent transferases. This domain has a three layer alpha/beta/alpha sandwich topology, with mixed beta-sheets of 7 strands. The major region can be found in the following PLP-dependent transferase families:

  • Aspartate aminotransferase (AAT)-like enzymes, such as aromatic aminoacid aminotransferase AroAT, glutamine aminotransferase and kynureninase [PubMed17300176].
  • Beta-eliminating lyases, such as tyrosine phenol lyase and tryptophanase [PubMed16790938].
  • Pyridoxal-dependent decarboxylases, such as DOPA decarboxylase and glutamate decarboxylase beta (GadB) [PubMed15690345].
  • Cystathionine synthase-like enzymes, such as cystalysin, methionine gamma-lyase (MGL), and cysteine desulphurase (IscS) [PubMed17014820].
  • GABA-aminotransferase-like enzymes, such as ornithine aminotransferase and serine hydroxymethyltransferase [PubMed15848278].
  • Ornithine decarboxylase major domain [PubMed10666573].

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 88 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 PLP-dependent transferases 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 88 hidden Markov models representing the PLP-dependent transferases superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
