Qhov sib txawv tseem ceeb ntawm phosphorylase thiab phosphatase yog tias phosphorylase enzymes catalyze cov tshuaj tiv thaiv cuam tshuam nrog kev hloov pauv ntawm phosphate pawg ntawm cov tebchaw, hos phosphatase enzymes catalyze cov tshuaj tiv thaiv uas cuam tshuam nrog kev tshem tawm ntawm pawg phosphate los ntawm kev sib xyaw ua ke ntawm phosphate. byproduct.
Phosphorylase thiab phosphatase yog ob qhov sib txawv enzymes uas koom nrog hauv kev ua kom muaj kev cuam tshuam biochemical, uas suav nrog cov substrates nrog phosphate pawg.
Phosphorylase yog dab tsi?
Phosphorylase yog ib qho enzyme uas catalyzes ntxiv ntawm phosphate pawg mus rau phosphate txais. Hauv cov tshuaj tiv thaiv no, phosphorylase ntxiv cov phosphate pawg no los ntawm ib qho inorganic phosphate. Phosphorylase muaj xws li allosteric enzymes uas tuaj yeem ua rau kev tsim cov piam thaj-1-phosphate los ntawm cov substrate xws li glucan.
Daim duab 01: Phosphorylase Enzyme
Phosphorylase enzymes muaj nyob rau hauv chav kawm enzyme ntawm kev hloov pauv. Qhov no yog vim cov enzymes hloov phosphate functional pawg los ntawm ib qho chaw mus rau lwm qhov. Muaj ntau hom phosphorylase enzymes, xws li Glycosyltransferases thiab Nucleotidyltransferases. Txawm li cas los xij, muaj ob hom phosphorylase li phosphorylase a thiab phosphorylase b. ntawm lawv, thiab phosphorylase ib yog daim ntawv nquag.
Phosphatase yog dab tsi?
Phosphatase yog ib hom enzyme uas siv dej txhawm rau phosphoric acid kom tau phosphate ion thiab cawv. Yog li ntawd, nws yog ib qho enzyme uas tshem tawm pawg phosphate los ntawm ib qho chaw. Hauv cov tshuaj tiv thaiv no, cov enzyme catalyzes hydrolysis ntawm lub substrate, uas ua rau nws lub npe raws li ib tug subcategory ntawm hydrolases. Tsis tas li ntawd, cov enzymes no tseem ceeb heev hauv cov kab mob lom. Cov txheej txheem uas cov enzyme no koom nrog yog hu ua dephosphorylation.
Hauv qhov sib piv rau phosphatase, phosphorylases hloov phosphate pawg ntawm cov tebchaw, thiab kinases catalyze cov tshuaj tiv thaiv ntawm kev hloov ntawm phosphate pawg los ntawm ATP rau molecules. Yog li, phosphatase thiab kinases yog qhov tseem ceeb hauv kev hloov pauv tom qab hloov pauv. Nws yog cov txheej txheem tseem ceeb hauv lub xov tooj ntawm tes kev tswj hwm.
Daim duab 02: Phosphatase Enzyme Molecule
Feem ntau, phosphate enzymes catalyze hydrolysis ntawm phosphomonoesters kom tshem tawm phosphate moiety los ntawm substrate. Hauv cov tshuaj tiv thaiv no, cov dej molecule sib cais, thiab -OH pawg txuas rau phosphate ion, thiab cov proton (H + ion) protonates hydroxyl pab pawg ntawm lwm yam byproduct. Cov tshuaj tiv thaiv no ua rau kev puas tsuaj ntawm phosphomonoester thiab tsim cov phosphate ion thiab cawv molecule uas muaj ib pab pawg hydroxyl dawb.
Feem ntau, phosphate enzymes yog ib chav loj ntawm cov enzymes, thiab muaj txog 104 cov enzymes txawv. Peb tuaj yeem faib cov enzymes no los ntawm qhov tshwj xeeb ntawm cov substrate thiab los ntawm cov kab ke homology hauv catalytic domains. Txawm li cas los xij, tag nrho cov enzymes no hauv txhua pawg ua haujlwm hauv tib lub hauv paus ntsiab lus uas lawv catalyze cov tshuaj tiv thaiv uas cuam tshuam nrog phosphate pawg tshem tawm los ntawm cov tebchaw.
Qhov txawv ntawm Phosphorylase thiab Phosphatase yog dab tsi?
Phosphorylase thiab phosphatase yog ob lub enzymes sib txawv. Qhov sib txawv tseem ceeb ntawm phosphorylase thiab phosphatase yog tias phosphorylase enzymes catalyze cov tshuaj tiv thaiv cuam tshuam nrog kev hloov ntawm phosphate pawg ntawm cov tebchaw, hos phosphatase enzymes catalyze cov tshuaj tiv thaiv uas cuam tshuam nrog kev tshem tawm ntawm pab pawg phosphate los ntawm kev sib xyaw ua phosphate ion thiab cawv.

Summary – Phosphorylase vs Phosphatase
Phosphorylase thiab phosphatase yog ob qhov sib txawv enzymes uas koom nrog hauv catalyzing biochemical cov tshuaj tiv thaiv, suav nrog cov substrates nrog phosphate pawg. Qhov sib txawv tseem ceeb ntawm phosphorylase thiab phosphatase yog tias phosphorylase enzymes catalyze cov tshuaj tiv thaiv cuam tshuam nrog kev hloov pauv ntawm phosphate pawg ntawm cov tebchaw, hos phosphatase enzymes catalyze cov tshuaj tiv thaiv uas cuam tshuam nrog kev tshem tawm ntawm pab pawg phosphate los ntawm kev sib xyaw ua phosphate ion thiabib qho cawv.
