应用

肌苷 5′-三磷酸盐 (ITP) 用于各种酶和化学过程对 ATP 和 GTP 脱氨作用影响的研究。ITP 可作为研究核苷-5′ 的特异性和动力学的底物-三磷酸酶和 atp 酶。ITP 也用于研究各种 atp 酶和 gtp 酶的激活。
肌苷 5′-本文研究了三磷酸三钠盐对人外周血淋巴细胞染色体畸变率、有丝分裂率、姐妹染色单体互换 (SCE) 频率、第一分裂中期 (X1)、第二分裂中期 (X2) 和第三分裂中期 (X3) 的影响。

生化/生理作用

肌苷 5′——三磷酸盐 (ITP) 具有支持效应系统启动的能力。可阻止鸟苷 5′——三磷酸鸟苷 (GTP) 水解,由转导素 (TD) 催化。与 GTP 相比,ITP 能熟练诱导透化细胞分泌。ITP 代替 GTP 可用于呼肠孤病毒转录的起始和延伸步骤。ITP 在 G 蛋白的激活中也能取代 GTP。

Phosphofructokinase from Jaculus orientalis muscle is an allosteric enzyme regulated by substrates and nucleotide effectors. The conformational modifications upon ligand binding were probed by UV difference spectra and reactivities of thiol groups towards dithiobisnitrobenzoate and N-ethylmaleimide. The binding of Fru-6-P

Infrared spectroscopy has been used to map substrate-protein interactions: the conformational changes of the sarcoplasmic reticulum Ca(2+)-ATPase upon nucleotide binding and ATPase phosphorylation were monitored using the substrate ATP and ATP analogues (2'-deoxy-ATP, 3'-deoxy-ATP, and inosine 5'-triphosphate), which were modified

Cryptococcus neoformans is the causative agent of pulmonary cryptococcosis and cryptococcal meningoencephalitis, which are major clinical manifestations in immunosuppressed patients. In the present study, a surface ATPase (ecto-ATPase) was identified in C. neoformans yeast cells. Intact yeasts hydrolyzed adenosine-5'-triphosphate (ATP)
