prothrombinase

prothrombinase

9.9
A group of proteins that helps blood form clots by changing prothrombin into thrombin
  • noun
  • /proʊˈθrɑːmbɪneɪs/
  • Specialized
translation icon : protrombinasa
  • Prothrombinase is an essential enzyme that helps convert prothrombin into thrombin during the clotting process.

Examples

  • The formation of prothrombinase on platelets is essential for rapid thrombin generation during wound healing.

  • A deficiency in prothrombinase activity can result in impaired blood clotting and excessive bleeding.

  • Prothrombinase plays a critical role in the final steps of the blood coagulation cascade.

  • The prothrombinase complex plays a crucial role in blood clotting.

  • Without prothrombinase, the coagulation process would fail.

  • Deficiencies in prothrombinase can lead to serious bleeding disorders.

  • In the coagulation cascade, prothrombinase is critical for ensuring effective blood clot formation.

Morphology

prothrombinase = prothrombin (transparent) = prothrombin + ase

Formed by adding the productive enzyme suffix '-ase' to the noun 'prothrombin', clearly indicating an enzyme acting on prothrombin.

Etymology

Prothrombinase comes from three parts: pro- meaning 'before', thrombin from a word for 'clot', and -ase which marks an 'enzyme'. So prothrombinase is the enzyme that turns prothrombin into thrombin, the protein that makes blood 'clot', which is why the word is used for a key step in blood clotting.
