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 کاملThe Catabolism of the Purine Nucleotides
Since the first isolation of adenylic acid from hog blood by Hoffman (l), and from muscle by Embden and Zimmermann (2), many recent investigations have shown that other adenine-containing nucleotides, such as adenylpyrophosphoric acid (3-5), codehydrogenase I (6), and codehydrogenase II (7), are of widespread occurrence in animal tissues. The literature that deals with the investigations concer...
متن کامل6-Benzylsulfanyl-9H-purine
The phenyl ring of the title compound, C(12)H(10)N(4)S, a purine derivative, is oriented at a dihedral angle of 76.65 (6)° with respect to the purine ring system. An inter-molecular N-H⋯N hydrogen bonds stabilizes the crystal structure.
متن کامل6-(2-Methoxybenzylamino)purine
The title compound, C(13)H(13)N(5)O, consists of discrete mol-ecules connected by N-H⋯N hydrogen bonds to form infinite chains, with N⋯N separations of 3.0379 (15) and 2.8853 (15) Å. The benzene and purine ring systems make a dihedral angle of 77.58 (3)°. The crystal structure is further stabilized by intra-molecular N⋯O inter-actions [2.9541 (12) Å] and inter-molecular C-H⋯C and C⋯C contacts [...
متن کاملComplex formation of carnosine with purine nucleotides in aqueous solution.
This 1H-NMR study provides experimental evidence for an intermolecular interaction between the dipeptide carnosine (beta-alanyl-L-histidine) and the purine nucleoside 5'-monophosphates 5'-AMP, 5'-GMP. From the observed upfield shifts of the purine nucleotide and imidazole proton resonances it is concluded that the interaction is of the stacking type and that it involves the purine base of the n...
