the present results clearly show the involvement of two pathways contributing to deoxyguanosine-mediated inhibition of the proliferation of normal lymphocytes , i.e. , on the one hand degradation of deoxyguanosine by pnp , salvage of guanine by hgprt , and ( possibly ) phosphorylation of gmp eventually leading to gtp , and on the other hand formation of dgtp by direct phosphorylation of deoxyguanosine by deoxycytidine kinase .
