    • Luciferase-linked methods for detecting adenosine and for screening for inhibitors of enzymes that produce adenosine are disclosed. The invention also provides methods for detecting the presence of Sadenosyl-L-homocysteine hydrolase (SAHH) comprising: (a) hydrolysis of S-adenosyl-Lhomocysteine (SAH) catalyzed by S-adenosyl-L-homocysteine hydrolase (SAHH) to adenosine and L-homocysteine; (b) converting adenosine to adenosine monophosphate (AMP) by adenosine kinase in the presence of a phosphate donor; (c) converting AMP to adenosine 5 '-triphosphate (ATP) by pyruvate phosphate dikinase (PPDK) in the presence of phosphoenolpyruvate (PEP) and inorganic pyrophosphate; and (d) reacting A TP with luciferin and Oz in the presence of luciferase to produce AMP and a luminescent signal, wherein the luminescent signal indicates the presence of S-adenosyl-L-homocysteine hydrolase (SAHH).
    • 公开了用于检测腺苷和筛选产生腺苷的酶抑制剂的荧光素酶连接方法。 本发明还提供了用于检测Sadenosyl-L-同型半胱氨酸水解酶(SAHH)的存在的方法,其包括:(a)将S-腺苷-L-高半胱氨酸水解酶(SAHH)催化的S-腺苷 - 高半胱氨酸(SAH)水解成腺苷和 L-高半胱氨酸; (b)在磷酸盐供体存在下,通过腺苷激酶将腺苷转化为腺苷一磷酸(AMP); (c)在磷酸烯醇丙酮酸(PEP)和无机焦磷酸盐存在下,通过丙酮酸磷酸二激酶(PPDK)将AMP转化为5'-三磷酸腺苷(ATP); 和(d)在荧光素酶存在下使TP与荧光素和Oz反应以产生AMP和发光信号,其中发光信号表示S-腺苷-L-高半胱氨酸水解酶(SAHH)的存在。
