S-adenosylhomocysteine hydrolase is an adenosine-binding protein: a target for adenosine toxicity

MS Hershfield and NM Krodich

When adenosine deaminase activity is inhibited, low concentrations of adenosine are toxic to human lymphoblast mutants that are unable to convert adenosine to intracellular nucleotides. In order to identify the mediator of this cytotoxicity, we searched for a cytoplasmic protein capable of binding adenosine with high affinity. Such a protein was identified in extracts of human lymphoblasts and placenta as the enzyme S-adenosylhomocysteine hydrolase.
