Acetylation yog cov organic esterification cov tshuaj tiv thaiv nrog acetic acid. Nws nthuav tawm ib pawg acetyl ua haujlwm rau hauv cov tshuaj lom neeg. Cov tshuaj no yog hu ua acetate esters lossis acetates. Deacetylation yog qhov kev tawm tsam tawm tsam, tshem tawm ntawm pawg acetyl los ntawm cov tshuaj lom neeg.
Kev ua haujlwm ntawm acetylation yog dab tsi?
Acetylation neutralizes tus nqi zoo ntawm lysine thiab yog li cuam tshuam ntau yam ntawm cov protein ua haujlwm, xws li kev ruaj ntseg, kev ua haujlwm enzymatic, subcellular localization thiab kev cuam tshuam nrog lwm cov macromolecules hauv cell.
acetylation txhais li cas?
Mloog cov lus. (a-SEH-tih-LAY-shun) Ib tshuaj tshuaj tiv thaiv uas ib qho me me hu ua pawg acetyl ntxiv rau lwm cov molecules. Acetylation ntawm cov proteins yuav cuam tshuam li cas lawv ua hauv lub cev.
txhais li cas rau DNA ua acetylated?
Acetylation yog txheej txheem uas ib pawg acetyl ua haujlwm tau hloov pauv los ntawm ib lub molecule(qhov no, acetyl coenzyme A) mus rau lwm qhov. … Acetylation tshem tawm cov nqi zoo ntawm cov histones, yog li txo qis kev cuam tshuam ntawm N termini ntawm histones nrog cov phosphate tsis zoo ntawm pawg DNA.
Yuav ua li cas thaum cov protein yog acetylated?
Protein acetylation yog ib qho ntawm cov kev hloov pauv hloov pauv loj (PTMs) hauv eukaryotes, uas cov acetyl pawg los ntawm acetyl coenzyme A (Ac-CoA) is pauvmus rau ib qhov chaw tshwj xeeb ntawm cov saw hlau polypeptide. … Protein acetylation ib txwm tshwm sim nyob rau hauv ob hom sib txawv, uas ua ke ua lub cell-wide acetylome.
