Abstract

Extracts of wheat (Triticum vulgare Vill. [Triticum aestivum L.] var. Lemhi) seedlings contain thymidine-phosphorylating activity with ATP, ADP, or AMP and nucleotide hydrolase activity (ATP → → AMP). The synthesis of [32P]dTMP exclusively from [α-32P]ATP with none detectable from [γ-32P]ATP demonstrates the absence of thymidine kinase and the presence of nucleoside phosphotransferase as the only observable thymidine-phosphorylating enzyme.
