Cytosine deaminase
An enzyme that oxidizes 5-fluorouracil to 5-fluorouracil
Usage and Biology
result
Cytosine deaminase (CD) is the enzyme that can transform cytosine into uracil. CD’s function is to convert nontoxic 5-Flucytosine (5-FC) into toxic 5-fluorouracil 5-FU, which has an extreme damage to the bacteria.
We added gradient of 5-FC culturing the bacteria and monitor their growth.
Fig.1 Growth of E.coli at different concentration of 5-FC. Foster the bacteria (keeping the quantity of the bacteria same before 1% passaging : 2μl bacteria, OD=3.5) with a concentration gradient of 5-FC in the LB mediacontaining 50µg/ml Amp and str): 500mg/l, 250mg/l, 100mg/l, 50mg/l, 25mg/l, 0mg/l. A. The bacteria (E.coli) using T7 to express CD. B. The bacteria (E.coli) can`t express CD.
As a positive control, we added gradient of 5-FU culturing the bacteria and monitor their growth.
