Raws li Dominique hais tias, isoenzymes tau txhais hauv thawj qhov piv txwv los ntawm qhov tseeb uas lawv catalyze tib cov tshuaj tiv thaiv, thiab lawv yuav muaj qhov sib txawv kinetic zog rau qhov sib koom substrate, qee zaum txawv heev - piv txwv li. Hexokinase thiab glucokinase rau qabzib.
YPuas isozymes muaj cov substrates sib txawv?
Tshwj tsis yog lawv zoo ib yam hauv lawv cov khoom siv biochemical, piv txwv li lawv cov substrates thiab enzyme kinetics, lawv yuav raug cais los ntawm kev tshuaj ntsuam biochemical. Txawm li cas los xij, qhov sib txawv no yog feem ntau hloov maj mam, tshwj xeeb ntawm cov allozymes uas feem ntau tsis muaj qhov sib txawv.
Yuav ua li cas isozymes zoo ib yam thiab lawv txawv li cas?
Isozymes (tseem hu ua isoenzymes) yog homologous enzymes
uas catalyze tib cov tshuaj tiv thaiv tab sis txawv hauv cov qauv . Qhov sib txawv ntawm cov isozymes tso cai rau lawv tswj cov tshuaj tiv thaiv tib yam ntawm cov chaw sib txawv hauv cov hom. Hauv particular lawv txawv hauv cov amino acid sequences.
Yuav ua li cas isozymes txawv?
Isozymes lossis isoenzymes, yog cov enzymes uas sib txawv hauv cov amino acid ib ntus tseem ua rau cov tshuaj tiv thaiv tib yam. … Isozymes txawv ntawm allozymes, uas yog cov enzymes uas tshwm sim los ntawm allelic variation ntawm ib tug gene locus. Isozymes feem ntau tuaj yeem sib txawv ntawm ib leeg los ntawm cov khoom siv biochemical xws li electrophoretic mobility.
YPuas isoenzymes muaj cov qauv zoo ib yam?
Isoenzymes (tseem hu ua isozymes) yog lwm yamCov ntaub ntawv ntawm tib yam kev ua enzyme uas muaj nyob hauv ntau qhov sib txawv hauv cov ntaub so ntswg sib txawv. Isoenzymes txawv nyob rau hauv cov amino acid muaj pes tsawg leeg thiab ib theem zuj zus thiab multimeric quaternary qauv; feem ntau, tab sis tsis yog tas li, lawv muaj cov qauv zoo sib xws.
