Abstract

This entry represents the low molecular weight (LMW) protein-tyrosine phosphatases (or acid phosphatase), which act on tyrosine phosphorylated proteins, low-MW aryl phosphates and natural and synthetic acyl phosphates [PubMed1587862, PubMed1304913]. The structure of a LMW PTPase has been solved by X-ray crystallography [PubMed8052313] and is found to form a single structural domain. It belongs to the alpha/beta class, with 6 alpha-helices and 4 beta-strands forming a 3-layer alpha-beta-alpha sandwich architecture.

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 7 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 Phosphotyrosine protein phosphatases I 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 7 hidden Markov models representing the Phosphotyrosine protein phosphatases I superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
