Abstract

Pyridoxal-5'-phosphate-dependent enzymes (B6 enzymes) catalyze manifold reactions in the metabolism of amino acids. Most of these enzymes can be assigned to one of three different families of homologous proteins, the alpha, beta and gamma families. The alpha and gamma family might be distantly related with one another, but are clearly not homologous with the beta family. The beta family includes L- and D-serine dehydratase, threonine dehydratase, the beta subunit of tryptophan synthase, threonine synthase and cysteine synthase. These enzymes catalyze beta-replacement or beta-elimination reactions [PubMed8112347].

Comparison of sequences from eukaryotic, archebacterial, and eubacterial species indicates that the functional specialization of most B6 enzymes has occurred already in the universal ancestor cell. The cofactor pyridoxal-5-phosphate must have emerged very early in biological evolution; conceivably, organic cofactors and metal ions were the first biological catalysts [PubMed10800595].

The 3D structure of the beta-subunit of tryptophan synthase has been solved. The subunit has two domains that are approximately the same size and similar to each other in folding pattern. Each has a core containing a four-stranded parallel beta-sheet with three helices on its inner side and one on the outer side. The cofactor is bound at the interface between the domains [PubMed7748903].

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 22 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 Tryptophan synthase beta subunit-like PLP-dependent enzymes 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 22 hidden Markov models representing the Tryptophan synthase beta subunit-like PLP-dependent enzymes superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
