Application | Comment | Organism |
---|---|---|
medicine | enzyme is interesting for anticancer gene therapy since it deaminates the prodrug 5-fluorocytosine to the active drug 5-fluorouracil | Saccharomyces cerevisiae |
Cloned (Comment) | Organism |
---|---|
expression as His-tagged enzyme in Escherichia coli strain BL21 and as selenomethionine-labeled enzyme in strain B834 | Saccharomyces cerevisiae |
Crystallization (Comment) | Organism |
---|---|
purified recombinant wild-type and selenomethionine-labeled enzymes in 10% 2-propanol, 20% PEG 4000, 0.1 M Na HEPES, pH 7.5, at 4°C and at 22°C by hanging drop vapour diffusion method, 0.002 ml of both reservoir and protein solution are mixed in presence of 2-hydroxypyrimidine, 3-5 days to 1-2 weeks at 22°C, micro-seeding, X-ray diffraction structure determination and analysis at beyond 1.5 A resolution | Saccharomyces cerevisiae |
