Abstract

Purple acid phosphatases (PAPs) are ubiquitous binuclear metal-containing acid hydrolases characterised by their acidic pH optima and their intense purple colour due to a TyrO-to-FeIII charge-transfer transition. The amino acid residues coordinating the metal ions are conserved in all PAPs. Active PAPs contain an FeIII ion coordinated to Tyr O, a His N, and an Asp O2, in addition to a divalent metal ion (Fe, Zn, or Mn) coordinated by a His N, a His N, and an Asn O. A hydroxide ion and an Asp O2 bridge the two metal ions [PubMed12440878]. These enzymes share a high degree of homology within their N-termini [PubMed10510276].

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 2 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 Purple acid phosphatase, N-terminal 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 2 hidden Markov models representing the Purple acid phosphatase, N-terminal domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
