Tissue plasminogen activator (TPA) is a serine protease occurring in animals including humans. Human-identical TPA (produced industrially by genetically recombinant microorganisms) has an established medical use in the treatment of ischemic stroke: by its proteolytic activity it enables the action of another enzyme (plasmin), which breaks down the protein (fibrin) of blood clots.
Some enzymes are used commercially, for example, in the synthesis of antibiotics. Some household products use enzymes to speed up chemical reactions: enzymes in biological washing powders break down protein, starch or fat stains on clothes, and enzymes in meat tenderizer break down proteins into smaller molecules, making the meat easier to chew.
Function: Amylase is an enzyme that is responsible for the breaking of the bonds in starches, polysaccharides, and complex carbohydrates to be turned into simple sugars that will be easier to absorb. Clinical Significance: Amylase also has medical history in the use of Pancreatic Enzyme Replacement Therapy (PERT). One of the components is ...
A few class A enzymes, most noted the plasmid-mediated KPC enzymes, are effective carbapenemases as well. Ten variants, KPC-2 through KPC-11 are known, and they are distinguished by one or two amino acid substitutions (KPC-1 was re-sequenced in 2008 and found to be 100% homologous to published sequences of KPC-2). KPC-1 was found in North ...
The enzymes are from pigs. [5] Use is believed to be safe during pregnancy. [5] The components are digestive enzymes similar to those normally produced by the human pancreas. [6] They help the person digest fats, starches, and proteins. [5] Pancreatic enzymes have been used as medications since at least the 1800s. [7]
Protease inhibitors were the second class of antiretroviral drugs developed. The first members of this class, saquinavir , ritonavir , and indinavir , were approved in late 1995–1996. Within 2 years, annual deaths from AIDS in the United States fell from over 50,000 to approximately 18,000 [ 5 ] Prior to this the annual death rate had been ...
Medical uses [ edit ] The most important use of beta-lactamase inhibitors is in the treatment of infections known or believed to be caused by gram-negative bacteria , as beta-lactamase production is an important contributor to beta-lactam resistance in these pathogens.
Hyaluronidases are a family of enzymes that catalyse the degradation of hyaluronic acid. Karl Meyer classified these enzymes in 1971, into three distinct groups, a scheme based on the enzyme reaction products. [1] The three main types of hyaluronidases are two classes of eukaryotic endoglycosidase hydrolases and a prokaryotic lyase-type of ...
