Tyrosinase yog lub luag haujlwm rau thawj kauj ruam hauv kev tsim cov tshuaj melanin. Nws hloov cov protein tsev thaiv (amino acid) hu ua tyrosine mus rau lwm qhov chaw hu ua dopaquinone.
Qhov txawv ntawm tyrosine thiab tyrosinase yog dab tsi?
Tyrosinase yog ib qho enzyme uas muaj peev xwm ntawm ortho-hydroxylating tyrosine thaum CO tsuas yog oxidizes ortho-diphenols.
Yuav ua li cas thaum tyrosinase inhibited?
Siv Tyrosinase Inhibitor yuav pab tiv thaiv koj cov tawv nqaij thiab tiv thaiv koj los ntawm kev tsim hyperpigmentationthiab feem ntau hyperpigmentation yog pw hauv qab ntawm daim tawv nqaij thiab yuav tshwm sim tom qab hauv lub neej. Koj tuaj yeem tiv thaiv qhov hyperpigmentation los ntawm qhov tshwm sim lossis los ntawm qhov chaw tag nrho.
YYuav ua li cas thiaj tau tyrosinase?
Tyrosinase yog lub ntuj enzymes uas tuaj yeem tau txais los ntawm ntau qhov chaw xws li kab mob, fungi, nroj tsuag thiab tsiaj txhuthiab tsuas tuaj yeem ua kom huv mus rau qib qis heev. Ntau hom kab mob microbial tau tshaj tawm rau kev tsim cov tyrosinases zoo li Streptomyces glaucescens, Agaricus bisporus thiab Neurospora crassa.
Cov yam ntxwv ntawm tyrosinase yog dab tsi?
Cov qauv tag nrho ntawm tyrosinase tuaj yeem muab faib ua peb lub npe: lub hauv paus sau, N-terminal domain, thiab C-terminal domain. Lub hauv paus tseem ceeb, uas yog tsim los ntawm 6 qhov khaws cia histidine residues, muaj CuA thiab CuB oxidizing ions.
