Abstract

These sequences contain a plant domain of about 200 amino acids, characterised by four conserved cysteine residues. The functional importance of these residues has been studied in a pectinesterase inhibitor from Kiwi. The cysteine residues form two disulphide bonds: first to second and third to fourth [PubMed10880981]. Roughly half the members of this family have an adjacent C-terminal pectinesterase domain , suggesting that the pairing of the enzymatic domain and the cysteine domain reflect a conserved regulatory mechanism for this enzyme family.

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 3 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 Plant invertase/pectin methylesterase inhibitor 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 3 hidden Markov models representing the Plant invertase/pectin methylesterase inhibitor superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
