4-NITROPHENYL-ALPHA-D-MANNOPYRANOSIDE CAS:10357-27-4

Ma enzyme substrates: 4NPM ingagwiritsidwe ntchito ngati substrate ya ma enzyme osiyanasiyana, kuphatikizapo ma glycosidases ndi ma enzyme ena ofanana nawo. Ma enzyme amenewa amagawaniza mgwirizano wa glycosidic pakati pa mannose ndi 4NPM, zomwe zimapangitsa kuti nitrophenyl moiety itulutsidwe. Kukula kwa hydrolysis ya substrate kumatha kuyezedwa spectrophotometrically poyang'anira kuyamwa kwa gulu la nitrophenyl lotulutsidwa pamlingo winawake. Izi zimathandiza ofufuza kuwunika ntchito ya enzyme ndi kinetics.

Kuyesa kagayidwe ka chakudya m'thupi: Pogwiritsa ntchito 4NPM ngati gawo lapansi, ofufuza amatha kuphunzira momwe ma enzyme omwe amagwira ntchito mu kagayidwe ka chakudya m'thupi, monga alpha-mannosidases amagwirira ntchito. Ma enzyme amenewa amathira ma glycosidic bonds mu mankhwala okhala ndi mannose, ndipo ntchito yawo imatha kuyezedwa poyang'anira kutulutsidwa kwa nitrophenyl moiety kuchokera ku 4NPM.

Maphunziro a Glycosylation: 4NPM ingagwiritsidwenso ntchito poyesa kufufuza ma enzyme omwe amagwira ntchito mu glycosylation. Glycosylation ndi njira yolumikizira mamolekyu a shuga ku mapuloteni kapena mamolekyu ena, ndipo ma enzyme ambiri amagwira ntchito mu njirayi. Pogwiritsa ntchito 4NPM ngati gawo lolandirira, ofufuza amatha kuyeza kusamutsa kwa shuga kupita ku 4NPM ndi ma enzyme enaake omwe amagwira ntchito mu glycosylation reactions.

Kuyesa ma enzyme inhibitors kapena activators: 4NPM ingagwiritsidwe ntchito poyesa ma high-throughput screening assays kuti azindikire mankhwala omwe amaletsa kapena kuyambitsa ma enzyme enaake. Poyesa momwe ma test compounds amakhudzira hydrolysis kapena kusintha kwa 4NPM ndi ma enzyme omwe akufunidwa, ofufuza amatha kuzindikira mankhwala othandizira kapena ma probe othandiza pophunzira ntchito ya ma enzyme.
