Nco ntsoov tias nyob rau hauv ib txwm enzymatic kev sib tham, ib enzyme yuav paub thiab khi rau ib lub substrate thiaj li yuav catalyze cov tshuaj tiv thaiv. Nws mam li tso cov khoom. Kev sib tw inhibition yog qhov cuam tshuam ntawm ib qho cov enzymes muaj peev xwm los khi rau lub substrate vim muaj qhov sib txawv molecule khi rau qhov chaw nquag.

Nyob rau hauv tas li ntawd, yuav ua li cas inhibited enzymes?

Ib enzyme inhibitor yog ib qho molecule uas khi rau ib qho enzyme thiab txo nws txoj haujlwm. Kev khi ntawm ib inhibitor tuaj yeem nres lub substrate los ntawm nkag mus rau hauv cov enzymes active site thiab/los yog hinder enzyme los ntawm catalyzing nws cov tshuaj tiv thaiv.

Ib sab saum toj no, ua li cas thiaj li ua kom muaj enzyme? Enzyme Activation . Enzyme activation tuaj yeem nrawm los ntawm kev hloov kho biochemical ntawm cov enzyme (piv txwv li, phosphorylation) los yog los ntawm qhov tsis muaj molecular hnyav zoo modulators. Cov molecules no yuav tsum khi rau ib qhov chaw uas tsis yog lub substrate binding site, txwv tsis pub substrate khi tsis tuaj yeem tshwm sim.

Kuj tseem paub yog, inhibition cuam tshuam li cas rau kev ua enzyme?

Cov teebmeem ntawm Inhibitors ntawm Kev ua enzyme . Enzyme inhibitors yog cov khoom uas hloov cov catalytic kev ua ntawm enzyme thiab yog li ntawd qeeb, lossis qee zaum, nres catalysis. Kev sib tw inhibition tshwm sim thaum lub substrate thiab ib yam khoom zoo li lub substrate yog ob qho tib si ntxiv rau enzyme.

Dab tsi yog 3 hom enzyme inhibitors?

Muaj peb hom ntawm reversible inhibitors Kev sib tw, tsis sib tw / sib xyaw, thiab tsis sib tw inhibitors . Kev sib tw inhibitors , raws li lub npe qhia, sib tw nrog substrates los khi rau lub enzyme tib lub sijhawm. Cov inhibitor muaj affinity rau lub active site ntawm ib enzyme qhov twg lub substrate kuj khi rau.
