Definition of proteolysis in English:
proteolysis
noun ˌprəʊtɪˈɒlɪsɪsˌproʊdiˈɑləsəs
mass nounBiochemistry The breakdown of proteins or peptides into amino acids by the action of enzymes.
Example sentencesExamples
- However, most proteolysis takes place in the duodenum as a consequence of enzyme activities secreted by the pancreas.
- A protein resistant to heat and proteolysis that inhibits serine proteases was isolated from wheat leaf apoplasts.
- Chapter 5 focuses on the catabolism of proteoglycans, detailing mainly proteolysis and the host of proteases involved.
- As a cheese ages, fats and proteins break down through proteolysis, into simplified units via bacterial or fungal actions.
- Constitutive proteolysis, however, is the main source of free amino acids used for de novo protein synthesis.
Derivatives
adjective ˌprəʊtiːəˈlɪtɪkˌproʊdiəˈlɪdɪk
Biochemistry Fibrinogen and its proteolytic cleavage product, fibrin, are critical plasma proteins with multiple functions in blood clotting.
Example sentencesExamples
- With age and any degenerative condition, serum levels of proteolytic enzymes are at a much lower concentration.
- The biochemical degradation of proteins through hydrolysis of peptide bonds is caused by the action of proteolytic enzymes or proteases.
- Similar proteinases catalyse the proteolytic processing of these proteins and contribute to their complete breakdown during germination and seedling growth.
- Most notably, there are the proteolytic enzymes trypsin and chymotrypsin, which our bodies make.
adverbˌprəʊtiːəˈlɪtɪk(ə)li
Biochemistry The existence of these insoluble and proteolytically resistant deposits can seriously interfere with normal organ function.
Example sentencesExamples
- All 3 proteins are proteolytically regulated by sterols.
- Fibrin degradation means that thrombin must have been present to form fibrin and plasmin was present to proteolytically digest it.
- The proteolytically modified actins were used within 1 day.
- We therefore developed proteogest, a program that generates basic descriptive statistics for both the intact and proteolytically processed proteome.
Origin
Late 19th century: modern Latin, from protein + -lysis.
