| Pseudomonas serine proteinase | <enzyme> Extracellular proteases I, II, III have role in infectious process of pseudomonas aeruginosa; included in the group of microbial serine proteinases EC 3.4.21.4 Registry number: EC 3.4.21.- Synonym: pseudomonas aeruginosa protease, pseudomonas alkaline protease (26 Jun 1999) |
| human a1-proteinase inhibitor | A glycoprotein that is the major protease inhibitor of human serum, is synthesised in the liver, and is genetically polymorphic due to the presence of over 20 alleles; individuals appropriately homozygous are deficient in a1-trypsin and are predisposed to pulmonary emphysema and juvenile hepatic cirrhosis because of alterations in the amino acid and sialic acid components of the glycoprotein. A1-Antitrypsin also inhibits thrombin. Synonym: a1-trypsin inhibitor, human a1-proteinase inhibitor. (05 Mar 2000) |
