Transaminase Mechanism Transaminases ua cov tshuaj tiv thaiv kab mob uas NH2 amine pawg los ntawm cov amino acid pauv rau O pawg ntawm keto acid. Ntawm no, keto acid dhau los ua amino acid, thiab cov amino acid dhau los ua keto acid. Feem ntau ntawm cov transaminases ua haujlwm ntawm proteins.
YDab tsi yog transaminase ua dab tsi?
Aminotransferases lossis transaminases yog ib pab pawg ntawm cov enzymes uas ua kom muaj kev sib hloov ntawm cov amino acids thiab oxoacids los ntawm kev hloov ntawm cov amino pawg.
Dab tsi yog qhov kev hloov pauv ntawm kev hloov pauv?
Kev hloov pauv yog txheej txheem los ntawm cov amino pawg raug tshem tawm ntawm cov amino acids thiab xa mus rau cov neeg txais keto-acids los tsim cov amino acid version ntawm keto-acid thiab keto- acid version ntawm tus thawj amino acid.
Dab tsi yog transaminase tawg?
Transaminases lossis aminotransferases yog cov enzymes uas ua rau cov tshuaj tiv thaiv kev hloov pauv nruab nrab ntawm cov amino acid thiab α-keto acid. Lawv yog cov tseem ceeb hauv kev tsim cov amino acids, uas tsim cov proteins.
Yuav ua li cas aminotransferase enzymes catalyze cov tshuaj tiv thaiv?
Cov aminotransferases (ATs) (los yog transaminases) catalyze kev sib pauv ntawm ib pawg amino ntawm cov amino acid thiab oxoacid, kom cov amino acid hloov mus rau hauv oxoacid thiab vice versa (Equation (4)). Feem ntau, l-glutamate lossis 2-oxoglutarate muab ib qho ntawm ob khub ntawmreactants.
