Laccase yog tooj liab-muaj polyphenol oxidase, uas feem ntau muaj nyob rau hauv daim ntawv dimer lossis tetramer. Laccase tau pom thawj zaug los ntawm tus kws tshawb fawb Nyij Pooj Yoshi hauv cov pos hniav daj xim, thiab tom qab ntawd pom muaj nyob hauv cov kab mob, kab mob thiab kab mob kuj muaj nyob hauv laccase. Thaum kawg ntawm lub xyoo pua 19th, GB etranel thawj zaug cais nws raws li cov khoom siv kho mob los ntawm cov xim nyoos thiab hu ua laccase. Lub ntsiab qhov chaw ntawm laccase nyob rau hauv cov xwm yog cov nroj tsuag laccase, tsiaj laccase thiab microbial laccase. Microbial laccase tuaj yeem muab faib ua kab mob laccase thiab fungal laccase. Cov kab mob laccase feem ntau yog zais los ntawm lub xov tooj ntawm tes, thaum cov kab mob fungal feem ntau faib tawm sab nraud ntawm tes, uas yog hom kawm tshaj plaws tam sim no. Txawm hais tias cov nroj tsuag laccase ua lub luag haujlwm tseem ceeb hauv cov txheej txheem physiological ntawm lignocellulose synthesis thiab tsis kam mus rau lom thiab abiotic stresses, cov qauv thiab cov txheej txheem ntawm cov nroj tsuag laccase tsis paub.

Laccase tuaj yeem ua rau oxidation ntawm ntau tshaj 200 ntau hom tshuaj, dav siv hauv cov khoom noj, textile, ntawv thiab lwm yam lag luam. Laccase muaj cov khoom ntawm oxidizing phenolic tshuaj, uas tuaj yeem hloov mus rau hauv polyphenol oxides. Polyphenol oxides lawv tus kheej tuaj yeem ua polymerized los ua cov khoom loj, uas raug tshem tawm los ntawm cov khoom siv lim dej. Yog li laccase yog siv hauv kev tsim cov dej haus kom paub meej txog dej haus. Laccase tuaj yeem catalyze phenolic tebchaw hauv cov kua txiv hmab txiv ntoo thiab cov cawv txiv hmab tsis cuam tshuam rau cov xim thiab saj ntawm cov cawv. Laccase tau ntxiv rau cov txheej txheem kawg ntawm kev tsim npias kom tshem tawm cov pa oxygen ntau dhau thiab cov polyphenol oxides, yog li txuas ntxiv lub txee lub neej ntawm npias.
