β-Galactosidase muaj peb lub zog enzymatic (Fig. 1). Ua ntej, nws tuaj yeem tshem cov disaccharide lactose los tsim cov piam thaj thiab galactose, uas tuaj yeem nkag mus rau glycolysis. Qhov thib ob, cov enzyme tuaj yeem ua rau lub cev hloov pauv ntawm lactose rau allolactose, thiab, thib peb, cov allolactose tuaj yeem nkag mus rau monosaccharides.
Lub luag haujlwm ntawm beta galactosidase yog dab tsi?
β-galactosidase yog ib qho tseem ceeb rau kab mob raws li nws yog tus kws kho mob tseem ceeb hauv kev tsim lub zog thiab qhov chaw ntawm carbons los ntawm kev tawg ntawm lactose rau galactose thiab qabzib Nws yog kuj tseem ceeb heev rau cov zej zog uas tsis muaj lactose intolerant vim nws yog lub luag haujlwm ua cov mis nyuj tsis muaj lactose thiab lwm yam khoom siv mis nyuj.
beta galactosidase ua dab tsi hauv Lac operon?
β-Galactosidase (lacZ) muaj ob txoj haujlwm ua haujlwm. Nws hydrolyzes lactose rau galactose thiab qabzib thiab catalyzes lub intramolecular isomerization ntawm lactose rau allolactose, lac operon inducer.
Dab tsi yog beta galactosidase ib txwm zom?
Raws li ib qho enzyme, β-galactosidase cleaves lub disaccharide lactose los tsim galactose thiab qabzib uas thaum kawg nkag mus rau glycolysis. Cov enzyme no kuj ua rau cov tshuaj tiv thaiv transgalactosylation ntawm lactose mus rau allolactose uas thaum kawg cleaved rau monosaccharides.
E coli siv beta galactosidase li cas?
Kev ua tiav, lub luag haujlwm ntawm β-galactosidase hauv E. coli yog txhawm rau hydrolyze cov disaccharide lactose rau galactose thiab qabzib nrog rau hloov lactose mus rau lwm qhov disaccharide, allolactose, uas yog lub ntuj inducer rau lac operon.
