Ferredoxins yog cov protein me me uas muajhlau thiab sulfur atoms koom ua ke hlau-sulfur pawg. Cov "capacitors" lom neeg no tuaj yeem lees txais lossis tso tawm hluav taws xob, nrog rau cov txiaj ntsig ntawm kev hloov pauv hauv oxidation lub xeev ntawm cov hlau atoms ntawm +2 thiab +3.
ferredoxin nyob qhov twg?
Ferredoxins yog cov protein uas tsis muaj hlau tsis muaj hlau thiab feem ntau pom muaj nyob hauv cov kab mob anaerobic thiab hauv chloroplasts(11). Thawj qhov kev cais tawm yog los ntawm Clostridium pasteurianum thiab lub npe tiag tiag tau qhia txog xyoo 1962 (63).
Yuav ua li cas hauv ferredoxin?
Ferredoxin yog ib qho me me, muaj cov protein uas ua raws li tus txais hluav taws xob cuam tshuam nrog Photosystem kuv hauv photosynthesis. Nws txais ib qho hluav taws xob thiab txo qis, muab nws lub peev xwm los hla cov electrons uas yog ib feem ntawm cov txheej txheem thauj electron.
Lub luag haujlwm ntawm ferredoxin hauv photosynthesis yog dab tsi?
Cov nroj tsuag-hom ferredoxins (Fds) yog [2Fe-2S] cov proteins uas ua haujlwm feem ntau hauv photosynthesis; lawv transfer electrons los ntawm photoreduced Photosystem kuv rau ferredoxin NADP(+) reductase uas NADPH yog tsim rau CO(2) assimilation.
YPuas yog ferredoxin ib cofactor?
Nws muaj flavin cofactor, FAD . Cov enzyme no belongs rau tsev neeg ntawm oxidoreductases, uas siv hlau-sulfur proteins li electron pub thiab NAD+ los yog NADP+ ua electron txais. Qhov no enzymekoom nrog hauv photosynthesis.
