A hexokinase yog ib qho enzyme uas phosphorylates hexoses, tsim hexose phosphate. Hauv ntau cov kab mob, cov piam thaj yog cov khoom tseem ceeb tshaj plaws rau hexokinases, thiab glucose-6-phosphate yog cov khoom tseem ceeb tshaj plaws. Hexokinase muaj peev xwm hloov cov pawg inorganic phosphate los ntawm ATP mus rau substrate.
hexokinase nyob qhov twg?
Hexokinase I/A pom nyob rau hauv tag nrho cov ntaub so ntswg mammalian, thiab suav hais tias yog "lub tsev tu enzyme," tsis cuam tshuam los ntawm feem ntau lub cev, hormonal, thiab metabolic hloov. Hexokinase II / B yog tus thawj tswj hwm isoform hauv ntau hom cell thiab nce hauv ntau cov qog nqaij hlav. Nws yog hexokinase pom nyob rau hauv cov leeg thiab lub plawv.
Hexokinase yog dab tsi?
Nyob hauv cov ntaub so ntswg thiab kab mob feem ntau, glucose yog cov khoom tseem ceeb tshaj plaws ntawm hexokinases, thiab qabzib 6-phosphate yog cov khoom tseem ceeb tshaj plaws. Hexokinases tau pom nyob rau hauv txhua yam kab mob uas kuaj xyuas, xws li cov kab mob, cov poov xab, thiab cov nroj tsuag, mus rau tib neeg thiab lwm yam vertebrates.
YPuas hexokinase tsuas yog hauv daim siab?
Hexokinase D, ib qho isoenzyme pom tsuas yog hauv daim siab, muaj cov khoom tshwj xeeb. … Vim tias hexokinase D kev ua haujlwm tsis cuam tshuam los ntawm qabzib 6-phosphate, qhov enzyme no txhawb nqa lub siab lub peev xwm los tswj cov ntshav qabzib.
hexokinase 1 ua dab tsi?
Function. Raws li ib tug ntawm ob mitochondrial isoforms ntawm hexokinase thiab ib tug tswv cuab ntawm cov suab thajkinase tsev neeg, HK1 catalyzes tus nqi-txheej thiab thawj kauj ruam ntawm cov piam thaj metabolism, uas yog ATP-nyob ntawm phosphorylation ntawm qabzib rau G6P.
