Thymidine phosphorylase inhibits vascular smooth muscle cell proliferation.

Thymidine phosphorylase has been used in a study to evaluate biomarkers for advanced breast cancer patients treated with capecitabine-based first-line chemotherapy. Thymidine phosphorylase has also been used in a study to investigate implications for the clinical efficacy of nucleoside analogues.

一种对胸腺嘧啶可逆性转化为胸腺嘧啶进行催化的酶。 胸苷磷酸化酶是嘧啶核苷挽救途径的一部分。

一种对胸腺嘧啶可逆性转化为胸腺嘧啶进行催化的酶。胸苷磷酸化酶是嘧啶核苷挽救途径的一部分。该途径允许嘧啶碱基被回收用于核苷酸生物合成，而1-磷酸戊糖被转化为磷酸戊糖分流和糖酵解的中间体。 大肠埃希菌胸苷磷酸化酶与人序列具有40%的序列同源性，已发现该序列与血管生成剂血小板衍生的内皮生长因子相同。 在鸡绒膜尿囊膜测定中，纯化的大肠埃希菌酶已显示出刺激血管生长的作用。

Solution in 0.5 M potassium phosphate containing 2 mM uracil, 0.02% sodium azide and bovine serum albumin

Cloned from E. coli and produced in overexpressing E. coli

One unit will convert 1.0 μmole each of thymidine and phosphate to thymine and 2-deoxyribose 1-phosphate per min at pH 7.4 at 25°C.
