<p><b>New page</b></p><div>RuBisCO je okrajšava za ribulozo-1,5-bifosfat-karboksilaza/[[oksigenaza]]. Je encim, ki se nahaja v stromi kloroplasta in sodeluje v temotnih reakcijah pri [[fotosintezi]]/ v [[Calvinovem ciklu]]. Predstavlja 15% vseh proteinov v kloroplastu in velja za enega najbolj zastopanih encimov na Zemlji. <br />
<br />
<br />
== Zgradba encima ==<br />
RuBisCO je sestavljen iz šestnajstih podenot- osmih velikih in osmih malih, ki imajo skupno molsko maso okoli 540kDa. Velika podenota L z molsko maso 55kDa je zapisana v [[plastidni DNA]] kloroplasta, kjer se tudi sintetizira. V njej so vezavna mesta za substrat. <br />
Mala podenota S je zapisana v jedrni DNA, sintetizira se v [[citoplazmi]] in skozi membrano vstopa v kloroplast. Njena molska masa znaša 13kDa.<br />

<br />
<br />
== Reakcije encima ==<br />
RuBisCO se lahko obnaša kot karboksilaza ali oksigenaza, saj lahko sintetizira sadkorno molekulo [[RuBP]] (ribuloza-1,5-bifosfat) tako s CO2 kot tudi z O<sub>2</sub>. Glede na vrsto vezave plinastega substrata ločimo dva tipa reakcij: <br />
-vezava ogljika (CO<sub>2</sub>)<br />
-fotorespiracija (vezava O<sub>2</sub>)<br />
<br />
Pri vezavi CO<sub>2</sub> poteka reakcija med RuBP in CO<sub>2</sub> do nastanka 6C vmesnega produkta (2-keto-2-karboksiarabinitol-1,5-bifosfat), ki je neobstojen in zato razpade v dve molekuli 3-fosfoglicerata. [http://www.google.si/imgres?imgurl=http://guweb2.gonzaga.edu/faculty/cronk/biochem/images/rubisco-rxn.gif&imgrefurl=http://guweb2.gonzaga.edu/faculty/cronk/biochem/R-index.cfm%3Fdefinition%3DR&usg=__1_KCzooGgLHObAXiYICktz0FXq8=&h=251&w=710&sz=8&hl=sl&start=0&sig2=cTG5hpDyoYWr7LhpUE0WJw&zoom=1&tbnid=i0ZThI5ywkCV8M:&tbnh=74&tbnw=208&ei=EEsFTcDvDIvqOfqBxaYB&prev=/images%3Fq%3Drubisco%2Breaction%26hl%3Dsl%26client%3Dfirefox-a%26rls%3Dorg.mozilla:sl:official%26biw%3D1366%26bih%3D576%26gbv%3D2%26tbs%3Disch:1&itbs=1&iact=hc&vpx=83&vpy=352&dur=3420&hovh=133&hovw=378&tx=224&ty=111&oei=cUoFTcyIMJDxsgaM3qHtCQ&esq=4&page=1&ndsp=18&ved=1t:429,r:12,s:0 (slika: potek reakcije)]<br />
<br />
Pri fotorespiraciji pride do vezave molekule O<sub>2</sub> na RuBP, pri čemer nastaneta molekuli 3-fosfoglicerata in 2-fosfoglicerata. RuBisCO ima manjšo afiniteto do vezave s kisikom, saj tako poteče le 25% vseh reakcij.<br />
<br />
<br />
== Aktivnost encima ==<br />
V aktivno fazo RuBisCO preide s pomočjo [[RuBisCO aktivaze]]. Najprej se na encim s pomočjo ATP vežeta aminokislina [[lizin]] in RuBP, ki povzroči komformcijske spremembe im nato izstopi iz encima. Na lizin se veže CO<sub>2</sub>, ki se reducira v COO-, nanj pa kofaktor Mg<sup>2+</sup>2, ki povzroči aktivacijo encima. <br />
Na encimsko aktivnost vplivajo tudi pH, ki je podnevi zaradi svetlobnih reakcij fotosinteze 8, ponoči pa pade na 7 in deaktivira encim, pa tudi koncentracija kofaktorja Mg<sup>2+</sup>2, CO<sub>2</sub>.

<br />
RuBisCO je počasen encim (sintetizira 3-5 reakcij na min) in je glavni določevalec hitrosti temotnih reakcij.<br />
