proteinase Usage Examples

Converse of object

  • encode: We have characterized a number of cDNAs which encode proteinases to underpin optimization of proteinase inhibitors either alone or in combination.
  • call: The Kiwi fruit already contains a lot of a special enzyme called a proteinase.
  • contain: Several species have been found to contain proteinases in their latex.
  • secrete: Extracellular fungal products: Extracellular enzymes, particularly the secreted aspartyl proteinases, seem to be correlated with virulence of fungal pathogens.

Adjective modifier

  • aspartic: This could be an activated water molecule as seen in aspartic proteinases or an amino acid side chain.
  • papain-like: Identification of mouse hepatitis virus papain-like proteinase 2 activity.
  • main: Structure of coronavirus main proteinase reveals combination of a chymotrypsin fold with an extra alpha-helical domain.
  • other: Some enzymes may not participate directly in the cleavage of matrix proteins but instead are capable of activating other proteinases which degrade the matrix.
  • viral: Proteolytic processing by viral proteinases provides the active components of the viral replicase complex.
  • refolded: Incorporating CpTI into assays using fluorogenic substrates we were able to show that the serine PI inhibited the activity of the refolded proteinases.

Modifies a noun

  • inhibitor: Laboratory experiments look at the growth rates of fungi on substrates amended with proteinase inhibitors.
  • K: Cultures were labeled overnight, then washed and digested overnight in proteinase K before being counted in a liquid scintillation counter.
  • gene: The library was screened with a cysteine proteinase gene fragment originally amplified from cDNA of H. glycines.
  • activity: High levels of cysteine proteinase activity were detected in cryosections of nymphs of this insect.
  • digestion: This assay procedure is greatly simplified compared to the proteinase K digestion methods and is suitable for automation on an ELISA processor.
  • enzyme: The proteinase enzyme attacks the proteins clinging to the DNA and breaks them up thereby releasing the DNA.

Noun used with modifier

  • cysteine: We have used the paradigm of rational design from structural information to engineer more potent cysteine proteinase inhibitors offer.
  • serine: We are studying the structural biology of members of the serpin family of serine proteinase inhibitors using X-ray crystallography.
  • thiol: The overall mechanism of catalysis reaction by thiol proteinases is the same as in serine proteinases.
  • aspartyl: Extracellular fungal products: Extracellular enzymes, particularly the secreted aspartyl proteinases, seem to be correlated with virulence of fungal pathogens.
