Enzymatic synthesis of purine nucleotides.
The demonstration of a pathway of pyrimidine nucleotide synthesis in which PRPP’ is a key intermediate (1, 2) prompted a study to determine whether the same type of reaction mechanism might apply to the synthesis of purine nucleotides. In a preliminary note the condensation of adenine with PRPP to yield A5P was reported (3). Subsequent work has established the existence of enzymes in yeast whic...
متن کاملConcentrations of purine nucleotides and purine and pyrimidine bases in cerebrospinal fluid of neurologically healthy children.
The concentrations of the nucleotides AMP and IMP, the nucleosides adenosine, guanosine and inosine, the purine bases adenine, guanine, hypoxanthine and xanthine, urate, and the pyrimidine bases cytosine, thymine and uracil were determined by high performance liquid chromatography in the cerebrospinal fluid of 63 children aged between 1 month and 13 years who showed no sign of neurological dise...

تعداد 20 رأس میش نژاد نائینی 6+-24 ماهه، با میانگین وزن 2/3-+40 کیلوگرم، همراه با 20 رأس بره های آنها در قالب طرح کاملا تصادفی اثر بتائین و مکمل سولفات بر خصوصیات شیر و پشم و عملکرد بره ها بررسی شد. میش ها بطور تصادفی در چهار تیمار قرار گرفتند. تیمارها عبارت بودند از: 1-گروه شاهد 2-بتائین (05/0 درصد ماده خشک) 3-سولفات (24/0 سولفور درصد ماده خشک 4-بتائین هرماه با سولفات. جیره غذائی طبق nrc با مح...
15 صفحه اولMechanisms of synthesis of purine nucleotides in heart muscle extracts.
The key role of ATP, a purine nucleotide, in the conversion of chemical energy into mechanical work by myocardial tissue is well established (1, 2). The requirement for purine nucleotides has also been demonstrated in the multiple synthetic reactions which maintain all animal cells in the steady state. Since the question immediately arises whether the purine nucleotides are themselves in a stea...
