Tryptophan yog corepressor ntawm trp operon trp operon Trp operon muaj tsib yam genes: trpE, trpD, trpC, trpB, thiab trpA, uas encode enzymatic qhov chaw ntawm txoj kev.. Nws kuj muaj cov tshuaj tiv thaiv kab mob hu ua trpR. trpR muaj tus txhawb nqa qhov twg RNA polymerase khi thiab ua ke mRNA rau kev tswj hwm cov protein. https://en.wikipedia.org › wiki › Trp_operon
trp operon - Wikipedia
. Qhov kev hloov pauv tau tso cai rau tus neeg tawm tsam los khi rau tus neeg teb xov tooj qhov chaw ntawm operon. Tus neeg ntxeev siab ua txoj hauv kev, tiv thaiv RNA polymerase los ntawm kev sau cov noob caj noob ces.
Vim li cas tryptophan yog corepressor?
Thaum tryptophan nyob ib puag ncig, nws txuas rau cov tshuaj tiv thaiv molecules thiab hloov lawv cov duab kom lawv ua haujlwm. Ib tug me me molecule zoo li trytophan, uas hloov ib tug repressor rau hauv nws active lub xeev, hu ua ib tug corepressor.

Yuav ua li cas operon yog trp?
The trp operon yog ib qho piv txwv classic ntawm a repressible operon. Thaum tryptophan accumulates, tryptophan khi rau ib tug repressor, uas ces khi rau tus neeg teb xov tooj, tiv thaiv ntxiv transcription. Lub lac operon yog classicpiv txwv li ib tug inducible operon. Thaum lactose nyob hauv lub cell, nws hloov mus rau allolactose.
Corepressor molecule yog dab tsi?
Corepressors yog cov neeg tswj hwm kev hloov pauv uas tsis muaj peev xwm ntawm kev ywj pheej DNA khi, raug xaiv ncaj qha lossis tsis ncaj los ntawm DNA-binding TFs los tawm tsam cov hom phiaj qhia.
