ABSTRACT:
The present invention provides a procaryotic host cell stably transformed or transfected by a vector including a DNA sequence encoding for purine nucleoside phosphorylase or hydrolase. The transformed or transfected procaryotic host cell can be used in combination with a purine substrate to treat tumor cells and/or virally infected cells.
