Phenyl2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopyranoside CAS:24404-53-3

Phenyl2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopyranoside hangata e sebelisoa e le substrate bakeng sa enzyme β-galactosidase.Ha β-galactosidase e sebetsa holim'a eona, motsoako oa hydrolyzed, o baka tlhahiso ea p-nitrophenol kapa o-nitrophenol, e nang le 'mala o mosehla o ka bonoang habonolo.Sena se etsa hore e be molemo joalo ka karoloana ea litlhahlobo tse lekanyang tšebetso ea β-galactosidase.

Tšebeliso e 'ngoe e tloaelehileng ea Phenyl2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopyranoside e ka litlhahlobo tsa liphatsa tsa lefutso tsa moqolotsi oa litaba.Litlhahlobong tsena, mofuta oa thahasello o kopantsoe le lefutso la moqolotsi oa litaba, joalo ka mofuta oa beta-galactosidase.Mosebetsi oa moqolotsi oa litaba joale o hlahlojoa ka ho lekanya mosebetsi oa β-galactosidase o sebelisa Phenyl2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopyranoside e le substrate.Sena se lumella bafuputsi ho ithuta polelo ea liphatsa tsa lefutso le taolo.

Phenyl2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopyranoside e ka boela ea sebelisoa ho shebella li-inhibitors kapa activator tsa β-galactosidase.Ka ho hlahloba metsoako e fapaneng kapa bakuli ba lithethefatsi, bafuputsi ba ka tseba limolek'hule tse fetolang ts'ebetso ea enzyme ena, e ka bang le ts'ebeliso ea kalafo ho mafu kapa maemo a itseng.

Ho feta moo, motsoako ona o ka sebelisoa ho hloekisa protheine.β-galactosidase hangata e kopantsoe le liprotheine tse khahlang ho thusa ho lemoha le ho hloekisa.Phenyl2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopyranoside e ka sebelisoa e le substrate ho shebella le ho hloekisa liprotheine tsena tsa fusion ka ho lemoha mosebetsi oa β-galactosidase.
