Qhov sib txawv tseem ceeb ntawm hydrolase thiab hloov pauv yog tias hydrolase yog ib qho enzyme uas tshem covalent bonds los ntawm kev siv dej thaum transferase yog ib qho enzyme uas catalyzes hloov ntawm ib pawg ua haujlwm ntawm ib lub molecule mus rau lwm lub molecule.
Y Hydrolase thiab transferase yog ob hom enzymes uas catalyze biochemical tshua. Hydrolases siv dej txhawm rau txhawm rau txhawm rau covalent bonds hauv cov tebchaw. Hydrolases hydrolyze cov tebchaw rau hauv cov tebchaw me me. Transferases yog ib pawg ntawm cov enzymes uas ua rau kev hloov pauv ntawm cov dej tsis ua haujlwm los ntawm ib lub molecule mus rau lwm lub molecule. Lawv hloov acetyl, amino, methyl thiab phosphoryl pawg, thiab lwm yam.ntawm cov tebchaw.
Hydrolase yog dab tsi?
Hydrolase yog ib qho enzyme uas ua rau cov cleavage ntawm covalent bonds thiaj li hloov lawv mus rau hauv me me molecules. Hauv lwm lo lus, hydrolases catalyze hydrolysis ntawm cov tebchaw los ntawm kev siv dej. Yog li ntawd, hydrolases catalyze qhov sib ntxiv ntawm hydrogen thiab hydroxyl ions ntawm dej rau ib lub molecule. Raws li qhov tshwm sim, qhov sib xyaw ua ke tau muab faib ua ob lossis ntau dua yooj yim molecules.
Daim duab 01: Peptidase
Muaj ntau ntau hom hydrolases. Lipases, nucleases, glycosidases, proteases lossis peptidases yog ntau hom hydrolases. Lipases cleave ester bonds ntawm carboxylic acid thiab cawv hauv lipids thaum nucleases hydrolyze phosphodiester bonds hauv nucleic acids. Glycosidases tshem tawm glycosidic bonds hauv carbohydrates thaum peptidases rhuav peptide bonds hauv cov protein. Ib yam li ntawd, hydrolases hydrolyze siab molecular hnyav tebchaw rau hauv cov tebchaw me los yog lub tsev blocks.
Dab tsi yog Transferase?
Transferase yog ib qho enzyme uas catalyzes kev hloov ntawm ib pawg ua haujlwm los ntawm ib lub molecule (tus pub molecule) mus rau lwm lub molecule (acceptor molecule). Cov pab pawg ua haujlwm no yog pawg tsis muaj dej ua haujlwm. Transferases feem ntau hloov amine, carboxyl, carbonyl, methyl, acyl, glycosyl, thiab phosphoryl functional pawg los ntawm pub rau tus txais. Kev hloov ntawm ib pab pawg ua haujlwm yuav tshwm sim raws li kev hloov pauv nucleophilic.
Daim duab 02: Hloov pauv
Methyltransferases, formyltransferases thiab transaldolases yog ob peb hom kev hloov pauv. Methyltransferases hloov methyl (CH3) pab pawg los ntawm tus pub rau tus neeg txais. Formyltransferases catalyze hloov pauv ntawm pawg formyl (CHO) thaum transaldolases hloov peb cov pa roj carbon ketol. Ntxiv mus, acyl-transferases yog lwm hom kev hloov pauv uas ua rau muaj kev hloov pauv ntawm acyl pawg. Glycosyltransferase, sulfurtransferase thiab selenotransferase kuj yog cov enzymes hloov pauv.
Dab tsi yog qhov zoo sib xws ntawm Hydrolase thiab Transferase?
- Hydrolase thiab transferase yog ob hom enzyme uas ua cov tshuaj lom neeg ntawm cov tshuaj lom neeg.
- Lawv ua kom cov tshuaj tiv thaiv biochemical.
- Lawv yog cov protein thiab tshwj xeeb rau lawv cov substrates.
Qhov txawv ntawm Hydrolase thiab Transferase yog dab tsi?
Y Hydrolases yog enzymes uas catalyze hydrolysis ntawm cov tebchaw siv dej. Ntawm qhov tod tes, transferases yog cov enzymes uas ua rau kev hloov ntawm ib pawg ua haujlwm los ntawm ib qho molecule mus rau lwm qhov. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm hydrolase thiab transferase. Lipases, phosphatase, glycosidases, peptidases, thiab nucleosidases yog ntau hom hydrolases. Lub caij no, methyltransferases, formyltransferases, acyltransferase, glycosyltransferase, sulfurtransferase thiab transaldolases yog ob peb hom kev hloov pauv.
Hauv qab no yog ib daim ntawv qhia ntawm qhov sib txawv ntawm hydrolase thiab transferase.
Summary – Hydrolase vs Transferase
Y Hydrolase thiab transferase yog cov enzymes uas ua kom cov tshuaj tiv thaiv biochemical. Hydrolases catalyze cov hydrolysis ntawm cov khoom thaum hloov pauv hloov pauv hloov ntawm pawg ua haujlwm los ntawm ib lub molecule mus rau lwm qhov. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm hydrolase thiab transferase. Hydrolases siv dej thaum cov tshuaj tiv thaiv. Hauv qhov sib piv, cov hloov pauv siv cov pab pawg uas tsis yog dej ua haujlwm.
