Pmsf treatment to inhibit proteinase k
WebProteinase K activates the pro-rMTG without unwanted degradation of the histidine-tag. It turned out to be very important to inhibit proteinase K activity, e.g., by PMSF, prior to protein separation by SDS-PAGE.

WebApr 15, 2024 · In comparison, PMSF may have better membrane permeability and has been extensively used in numerous living yeast studies 39,40, but further detection of the status of vacuole upon PMSF treatment ... WebPMSF (phenylmethylsulfonyl fluoride) functions as a non-specific inhibitor of multiple proteases and other enzymes, such as palmityl coenzyme A deacylase, arylsulfatase A, acetylcholinesterase, trypsin and chymotrypsin. It is an irreversible inhibitor, and sulfonylates hydroxyl groups of the serine residues present in the active site of enzymes.
WebTo support this asseveration, we used the phenylmethylsulfonyl fluoride (PMSF) inhibitor of proteinase-3. Adding PMSF inhibitor at 6 h of culture, there was no increase in the absorbance if compared with the control proteinase-3-induced biofilm without PMSF inhibitor (p < 0.05), meanwhile the addition of PMSF after 10 h of culture stops the ...
