Nws yog tsim los ntawm kwv yees li 96 subunits koom ua peb lub luag haujlwm enzymes hauv tib neeg: 20-30 daim ntawv ntawm pyruvate dehydrogenase E1 tivthaiv, 60 daim ntawv ntawm pyruvate dehydrogenase E2 tivthaiv, thiab 6 daim ntawv luam ntawm dihydrolipoyl dehydrogenase (E3).
pom pyruvate decarboxylase nyob qhov twg?
a Pyruvate decarboxylase
Cov enzyme no muaj feem ntau hauv cov noob thiab tau kuaj pom hauv O. sativa (Hossain li al., 1994; Rivoal li al., 1990), Z. mays (Forlani et al., 1999) and Pisum sativum (Mücke et al., 1995). Thaum lub sij hawm ethanolic fermentation, acetaldehyde raug txo kom ethanol los ntawm cawv dehydrogenase.
pyruvate decarboxylase siv rau dab tsi?
Pyruvate decarboxylase (PDC, EC 4.1. 1.1) yog enzyme lub luag haujlwm rau cov tsis-oxidative decarboxylation ntawm pyruvate rau acetaldehyde thiab carbon dioxide.
Chav kawm twg puas pyruvate decarboxylase?
YPyruvate decarboxylase is a
homotetramer . Txhua lub subunit zoo ib yam muaj kwv yees li alternating α-helices thiab β-cov ntawv, thiab 2 qhov muaj nyob hauv txhua 60kDa subunit. Qhov no txhais tau tias nws SCOP qeb yog alpha thiab beta protein.
pyruvate decarboxylase yog dab tsi?
Pyruvate decarboxylase nyob ntawm cov cofactors thiamine pyrophosphate (TPP) thiab magnesiumCov enzyme no yuav tsum tsis txhob yuam kev rau cov enzyme uas tsis cuam tshuam nrog pyruvate dehydrogenase, oxidoreductase (EC 1.2. 4.1), uas. catalyzes oxidative decarboxylation ntawm pyruvate rau acetyl-CoA.
