| Abstract | Leeches, such as the medicinal leech Hirudo medicinalis, produce a variety of antihaemostatic proteins that act as proteinase inhibitors. These inhibitors are used to aid the leech in feeding upon its host by blocking blood coagulation [ 11563948, 11257492]. Examples of these proteins include hirustasin (inhibitor of tissue kallikrein, trypsin, alpha-chymotrypsin, and granulocyte cathepsin G) [10368273], bdellastasin (inhibitor of trypsin, plasmin, and acrosin) [10512718], factor Xa inhibitor antistasin (inhibitor of blood coagulation factor Xa) [9311976], hirudin (thrombin inhibitor), decorsin (inhibitor of platelet aggregation) [8607116] and haemadin (thrombin inhibitor) [11851400]. |

Alignments of sequences to 10 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 Leech antihemostatic proteins 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 10 hidden Markov models representing the Leech antihemostatic proteins superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
