Abstract

Pyruvate kinase controls the exit from the glysolysis pathway, catalysing the transfer of phosphate from phosphooenolpyruvate (PEP) to ADP. Mammalian pyruvate kinase is a homotetramer, where each polypeptide subunit consists of four domains: N-terminal, A domain, B domain and C-terminal. Activation of the enzyme is believed to occur via the clamping down of the B domain onto the A domain to dehydrate the active site cleft. The N- and C-terminal domains are situated at inter-subunit contact sites, and could be involved in assembly and communication within the complex. The N-terminal domain has a TIM beta/alpha-barrel structure. Homologous TIM-barrel domains are found in the following proteins:

  • N-terminal of pyruvate kinase , which is interrupted by an all-beta domain [PubMed11563914].
  • C-terminal of pyruvate phosphate dikinase , which has a similar mode of substrate binding to pyruvate kinase [PubMed11790099].
  • Phosphoenolpyruvate carboxylase ; this domain has additional helices [PubMed12467579].
  • Phosphenolpyruvate mutase/Isocitrate lyase , where it forms a swapped dimer [PubMed11526312].
  • HpcH/HpaI aldolases, such as the beta subunit of citrate lyase, where it forms a swapped dimer, and contains a pyruvate kinase-type metal binding site [PubMed7064730].
  • Ketopantoate hydroxymethyltransferase PanB , where a C-terminal helix exchange is observed in some enzymes [PubMed12906829].

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 24 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 Phosphoenolpyruvate/pyruvate domain 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 24 hidden Markov models representing the Phosphoenolpyruvate/pyruvate domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
