β-galactosidase yog ib qho exoglycosidase uas hydrolyzes β-glycosidic daim ntawv cog lus tsim ntawm galactose thiab nws cov organic moiety. Nws kuj tseem tuaj yeem tshem tawm fucosides thiab arabinosides tab sis nrog kev ua haujlwm qis dua. Nws yog ib qho enzyme tseem ceeb hauv tib neeg lub cev.
pom beta-galactosidase nyob qhov twg?
Lub noob GLB1 muab cov lus qhia rau kev tsim cov enzyme hu ua beta-galactosidase (β-galactosidase). Cov enzyme no nyob hauv lysosomes, uas yog cov khoom sib txuas hauv cov hlwb uas tawg thiab rov ua dua ntau hom molecules.
YPuas beta-galactosidase secreted?
Lub β-galactosidase nyob rau hauv nruab nrab tau tshwm sim los ua ib qho secreted, extracellular enzyme, tsis yog khoom ntawm cell lysis. Cov kev ua ub no tau pom tias muaj lub cev thiab lub cev muaj zog zoo ib yam li cov ntawm ib qho intracellular β-galactosidase yav dhau los pom hauv Neurospora.
YYuav ua li cas thaum beta-galactosidase?
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 transgalactosylation ntawm lactose rau allolactose, thiab, peb, cov allolactose tuaj yeem cleaved rau monosaccharides.
Qhov txawv ntawm lactase thiab beta-galactosidase yog dab tsi?
β-Galactosidase, feem ntau hu ua lactase, yog lub luag haujlwm enzyme rau hydrolyzelactose. Cov enzyme no muaj kev siv dav hauv kev lag luam ua zaub mov. … Qhov tsis txaus ntawm cov enzyme no hauv txoj hnyuv ua rau muaj lactose intolerance, thiab cov neeg uas raug kev txom nyem los ntawm nws tsis muaj peev xwm haus mis nyuj thiab khoom noj siv mis.
