Qhov sib txawv tseem ceeb ntawm lyases thiab transferases yog lawv txoj haujlwm tseem ceeb. Lyases yog cov enzymes uas catalyze dissociation los yog tawg ntawm molecules los ntawm cleaving lub bonds ntawm lawv. Lub caij no, cov tshuaj hloov pauv yog cov enzymes uas ua rau kev hloov pauv ntawm pawg ua haujlwm los ntawm ib lub molecule mus rau lwm lub molecule.
Y Enzymes yog biocatalysts ntawm biochemical tshuaj. Lawv yog cov proteins, thiab lawv ceev cov tshuaj biochemical los ntawm kev txo qis lub zog ntawm cov tshuaj tiv thaiv. Yog li ntawd, lawv nce tus nqi ntawm cov tshuaj tiv thaiv yam tsis tau noj. Lawv tuaj yeem ua rau cov tshuaj tiv thaiv biochemical dua thiab dua. Raws li cov tshuaj tiv thaiv cov enzymes catalyze, muaj rau pawg enzymes. Lawv yog cov Transferase, ligase, oxidoreductase, isomerase, hydrolase, thiab lyase. Ntawm cov no, cov lyases catalyze cov cleaving ntawm molecules thaum lub transferases catalyze hloov ntawm pawg ntawm molecules.
Lias yog dab tsi?
Lyases yog cov enzymes uas ua rau kev tawg lossis sib cais ntawm cov molecules. Cov enzymes siv dej los yog redox cov tshuaj tiv thaiv txhawm rau txhawm rau txhawm rau sib txuas ntawm cov molecules. Lyases feem ntau cleave C-C, C-N thiab C-O bonds ntawm molecules. Feem ntau qhov no ua rau kev tsim ntawm ob daim ntawv cog lus ntawm molecules. Nws kuj ua rau kev tsim cov qauv ntawm lub nplhaib. Lyases txawv ntawm hydrolases vim tsis ntxiv dej rau hauv cov khoom. Feem ntau cov lyases suav nrog decarboxylase, aldolases, dehydratases, thiab lwm yam.
Ib qho piv txwv ntawm cov tshuaj tiv thaiv biochemical uas catalyzes los ntawm lyase yog qhia hauv qab no.

Dab tsi yog Transferase?
Transferases yog cov enzymes uas ua rau kev hloov pauv ntawm pawg ua haujlwm los ntawm ib lub molecule mus rau lwm lub molecule. Yog li ntawd, transferases pab txhawb kev hloov ntawm ib pab pawg los ntawm tus neeg pub khoom molecule mus rau tus txais molecule. Kinases yog qhov piv txwv zoo tshaj plaws ntawm kev hloov pauv. Lawv catalyze hloov ntawm ib pab pawg phosphate los ntawm ATP mus rau lwm yam molecule. Cov pab pawg ua haujlwm uas hloov los ntawm kev hloov pauv muaj xws li methyl, glycosyl, aldehyde, ketone, alkyl lossis aryl, cawv thiab carboxyl, thiab lwm yam. Raws li pab pawg ua haujlwm, muaj cov subclasses ntawm kev hloov pauv.

Coenzyme A (CoA) transferase, peptidyl transferase, uridyl transferase, catechol-O-methyltransferase, methylamine-glutamate N-methyltransferase, nucleotidyl transferase, acyltransferase, glycosyltransferase, hexosyltransferase, thiab pentosyltransferase ntau yam.
Dab tsi yog qhov zoo sib xws ntawm Lyases thiab Transferases?
- Lyases thiab hloov pauv yog ob ntawm rau rau pawg loj ntawm enzymes.
- Lawv catalyze biochemical cov tshuaj tiv thaiv thiab nce tus nqi ntawm cov tshuaj tiv thaiv los ntawm kev txo qis lub zog ua kom muaj zog.
- Lawv yog tsim los ntawm cov amino acid sequences. Li no, lawv yog cov proteins thiab muaj qhov chaw nquag los khi nrog lawv cov substrates.
- Lawv koom nrog ntau txoj hauv kev biochemical tseem ceeb hauv cov kab mob nyob.
- Qhov tseeb, lawv yog qhov tseem ceeb ntawm cov txheej txheem tseem ceeb hauv lub neej.
Qhov txawv ntawm Lyases thiab Transferases yog dab tsi?
Lyase yog ib qho enzyme uas catalyzes kev tawg ntawm ntau yam tshuaj bonds los ntawm lwm yam tsis yog hydrolysis thiab oxidation. Lub caij no, transferase yog ib qho enzyme uas catalyzes kev hloov ntawm ib pab pawg neeg ua haujlwm los ntawm tus pub rau tus neeg txais. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm lyases thiab transferases. Decarboxylase, aldolases, dehydratases, thiab lwm yam yog ob peb yam piv txwv ntawm lyases. Thiab, coenzyme A (CoA) transferase, peptidyl transferase, uridyl transferase, catechol-O-methyltransferase, methylamine-glutamate N-methyltransferase, nucleotidyl transferase, acyltransferase, glycosyltransferase, hexosyltransferase, thiab pentosyltransferase.
Hauv qab infographic qhia txog qhov sib txawv ntawm lyases thiab transferases.
Summary – Lyases vs Transferases
Lyases catalyze qhov kev rhuav tshem ntawm ntau yam tshuaj tiv thaiv los ntawm kev txhais tau tias tsis yog hydrolysis thiab oxidation. Yog li ntawd, lyases cleave chemical bonds thiab txhawb kev tawg ntawm molecules los ntawm kev tsim ob daim ntawv cog lus ntawm C molecules thiab tsim cov qauv nplhaib. Lub caij no, cov hloov pauv hloov pauv hloov pauv ntawm pawg ua haujlwm los ntawm ib lub molecule mus rau lwm qhov. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm lyase thiab transferase. Ob leeg lyases thiab transferases yog ob pawg tseem ceeb ntawm cov enzymes uas yog ib feem ntawm ntau yam tseem ceeb biochemical tshwm sim tshwm sim hauv lub neej.
