Adenosine synthesis was studied during 2-deoxyglucose-induced ATP catabolism in intact rat polymorphonuclear leucocytes. When both adenosine kinase (EC 2.7.1.20) and adenosine deaminase (EC 3.5.4.4) were selectively inhibited, adenosine accumulated. Adenosine formation took place inside the intact cells by a metabolic pathway independent of the ecto-5'-nucleotidase (EC 3.1.3.5). Distinct metabolic pathways are proposed for adenosine production from intracellular or extracellular nucleotides.
在完整大鼠多形核白细胞中,研究了2-脱氧葡萄糖诱导的ATP分解代谢过程中的腺苷合成。当腺苷激酶(EC 2.7.1.20)和腺苷脱氨酶(EC 3.5.4.4)均被选择性抑制时,腺苷会积累。腺苷的形成通过一条独立于胞外5'-核苷酸酶(EC 3.1.3.5)的代谢途径在完整细胞内发生。针对由细胞内或细胞外核苷酸产生腺苷提出了不同的代谢途径。
