Phosphate-transfer reactions of adenosine and inosine nucleotides.
but purified adenylate kinase of muscle tissue does not catalyse reaction (2). It is possible that the enzyme is identical with the adenylate kinase of other tissues, which, according to Kotelnikova (1949, 1950) and Barkulis & Lehninger (1951), differs from the muscle-adenylate kinase. It is also possible that the transfer is the result of the combined action of reactions (3) and (1). In this c...
متن کامل2'-O-methylation of adenosine, guanosine, uridine, and cytidine in RNA of isolated rat liver nuclei.
Nuclei isolated from rat liver, when incubated with methyl-labeled S-adenosylmethionine, incorporated label into 2'-O-methyladenosine, 2'-O-methylguanosine, 2'-O-methyluridine, and 2'-O-methylcytidine of endogenous nuclear RNA. Addition of ribosomal RNA from wheat germ to the reaction markedly stimulated 2'-O-methylation of total RNA. The relative incorporation of label into the four different ...
متن کاملAdenosine Triphosphate : Guanosine Monophosphate Phosphotransferase
Several laboratories have reported studies on individual enzymes that belong to the general class of adenosine triphosphate : nucleoside monophosphate phosphotransferases (EC 2.7.4.4), commonly termed nucleoside monophosphate kinases (l-7). Studies with partially purified enzyme preparations have indicated that a variety of nucleoside monophosphates can serve as alternative substrates for nucle...
متن کاملStimulation of fluid secretion of malpighian tubules of drosophila melanogaster meig. by cyclic nucleotides of inosine, cytidine, thymidine and uridine
External application of the 3',5'-cyclic monophosphates of inosine, cytidine, uridine and thymidine stimulated the fluid secretion rate (FSR) of Malpighian tubules isolated from Drosophila melanogaster. The evidence suggested that the cyclic nucleotides acted intracellularly in some capacity. Receptors of the 'purinergic' type appeared not to be major contributors to fluid secretion; of three p...
متن کاملDNAzyme-mediated catalysis with only guanosine and cytidine nucleotides
Single-stranded DNA molecules have the capacity to adopt catalytically active structures known as DNAzymes, although the fundamental limits of this ability have not been determined. Starting with a parent DNAzyme composed of all four types of standard nucleotides, we conducted a search of the surrounding sequence space to identify functional derivatives with catalytic cores composed of only thr...
