Phosphatase catalyze hydrolysis ntawm phosphomonoester, tshem tawm phosphate moiety los ntawm substrate. Cov dej tau muab faib rau hauv cov tshuaj tiv thaiv , nrog rau pawg -OH txuas rau phosphate ion, thiab H + protonating pawg hydroxyl ntawm lwm yam khoom.

Ntawm no, phosphatase thiab kinases yog dab tsi?

Protein kinases thiab phosphatase yog cov enzymes catalysing hloov phosphate ntawm lawv cov substrates. Ib qho protein kinase catalyses hloov ntawm -phosphate los ntawm ATP (los yog GTP) rau nws cov protein substrates thaum muaj protein ntau phosphatase catalyses hloov ntawm phosphate los ntawm phosphoprotein mus rau ib qho dej molecule.

phosphatase substrate ua haujlwm li cas? Phosphatase . Phosphatase yog cov enzymes extracellular uas catalyze hydrolysis ntawm phospho-ester bonds hauv organic P-muaj substrate tso inorganic P nyob rau hauv daim ntawv ntawm orthophosphates uas tau siv los ntawm av biota thiab nroj tsuag.

Ib yam li ntawd, koj tuaj yeem nug, phosphatase puas siv ATP?

Phosphatase yog hydrolases; lawv siv dej muab tshem a phosphate los ntawm substrate (dephosphorylation). Kinases yog cov enzymes uas feem ntau hloov lub davhlau ya nyob twg phosphate pab pawg ntawm ATP mus rau ib pawg -OH ntawm lub substrate (phosphorylation).

Yuav ua li cas phosphatase activated?

Phosphoprotein phosphatase yog qhib los ntawm cov tshuaj hormone insulin, uas qhia tias muaj cov piam thaj ntau hauv cov ntshav. Cov enzyme tom qab ntawd ua rau dephosphorylate lwm cov enzymes, xws li phosphorylase kinase, glycogen phosphorylase, thiab glycogen synthase.
