Abstract

The histidine triad motif (HIT) is related to the sequence H-phi-H-phi-H-phi-phi (where phi is a hydrophobic amino acid). Proteins containing HIT domains form a superfamily of nucleotide hydrolases and transferases that act on the alpha-phosphate of ribonucleotides [PubMed12119013]. HIT-containing proteins fall into three families:

  • Hint family of protein kinase-interacting proteins. These include adenosine 5'-monophosphoramide hydrolases (e.g. HIT-nucleotide-binding protein, or HINT) and diadenosine polyphosphate hydrolases (e.g. fragile HIT protein, or FINT). These HIT domains have a topology similar to that found in the N-terminal of protein kinases [PubMed15904496].
  • GalT family. These include specific nucleoside monophosphate transferases (e.g. galactose-1-phosphate uridylyltransferase, diadenosine tetraphosphate phosphorylase, and adenylyl sulphate:phosphate adenylytransferase). These HIT domains are a duplication consisting of 2 HIT-like motifs. This family binds zinc and iron.
  • mRNA decapping enzyme family. These include enzymes such as DcpS and Dcp2. The HIT-domain is usually C-terminal in these proteins [PubMed15273322].

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 27 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 HIT-like 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 27 hidden Markov models representing the HIT-like superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
