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 e atisa ho sebelisoa e le substrate bakeng sa enzyme β-galactosidase. Ha β-galactosidase e sebetsa ho eona, motsoako o hasoa, e leng se fellang ka tlhahiso ea p-nitrophenol kapa o-nitrophenol, e nang le 'mala o mosehla o ka bonoang habonolo. Sena se etsa hore e be molemo e le substrate bakeng sa liteko tse lekanyang ts'ebetso ea β-galactosidase.

Tšebeliso e 'ngoe e tloaelehileng ea Phenyl2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopyranoside e litekong tsa liphatsa tsa lefutso tsa moqolotsi oa litaba. Litekong tsena, liphatsa tsa lefutso tse khahlisang li hokahantsoe le liphatsa tsa lefutso tsa moqolotsi oa litaba, joalo ka liphatsa tsa lefutso tsa beta-galactosidase. Mosebetsi oa liphatsa tsa lefutso tsa moqolotsi oa litaba o beoa leihlo ka ho lekanya mosebetsi oa β-galactosidase ho sebelisoa Phenyl2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopyranoside e le substrate. Sena se lumella bafuputsi ho ithuta polelo le taolo ea liphatsa tsa lefutso.

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

Ho phaella moo, motsoako ona o ka sebediswa tlhoekisong ya protheine. Hangata β-galactosidase e kopanngwa le diprotheine tse kgahlehang ho nolofatsa ho di lemoha le ho di hlwekisa. Phenyl2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopyranoside e ka sebediswa e le substrate ho hlahloba le ho hlwekisa diprotheine tsena tsa fusion ka ho lemoha mosebetsi wa β-galactosidase.
