Guanylic acid 5 -phosphate

The second step in the conversion of inosinic acid to guanylic acid is the aminolysis of xanthylic acid with glutamine by xanthosine-5 -phosphate aminase [65]. This aminase, isolated fromf. coli B, is inhibited allosterically by adenosine and adenylic acid [320], and it is also inhibited by psicofuranine (9-0-D-psicofuranosyladenine) (LXXIV) [284, 321-326], which apparently is not...

Holy and Sorm (49, 50) observed that RNase T2, like RNase Ti, attacks 9-(/3-D-ribofuranosyl) and 9-(a-L-lyxofuranosyl) derivatives but not 9-(j8-L-ribofuranosyl) and 9-(a-D-lyxofuranosyl) derivatives. Also, like RNase RNase T2 is quite inactive on the phosphodiester bonds of the nucleotide with 2 -0-methyl ribose, such as 2 -0-methyl guanylic acid (96) or 2 -0-methyl cytidylic acid (86). Thus, the action of RNase T2 is in good accord with that of RNase Ti and RNase A on sugar specificity, which may be a common property throughout all RNases, producing 3 -phosphate via 2, 3 -cyclic phosphate.

RNA contains the nucleotide bases adenine (A), uracii (Lf), guanine (G), and Cytosine (C). These bases are cox alently attached to the ribose phosphate to form nucleotides. The respective nucleotides ate called adenylic acid (A), uridylic acid (U), guanylic acid (G), and cytidylic acid (C>,...

It is now known that mild, alkaline hydrolysis of ribonucleic acids yields mixtures of the 2 - and 3 -phosphates of ribonucleosides, although it had earlier been believed that only the 3 -phosphate derivatives are produced. For example, it was reported that guanylic acid (6), obtained from ribonucleic acid hydrolysates, is deaminated with nitrous acid to xanthylic acid (7), which was hydrolyzed at pH 1.9 to a ribose phosphate...

A nucleoside in which a hydroxyl group of one of the sugar moieties is esterified with a phosphoric acid is called a nucleotide. For example, placing a phosphate at the 5 -position of adenosine and guanosine, each possessing purine base, generates nucleotides, and these are named 5 -adenylic acid (AMP) and 5 -guanylic acid (GMP), respectively, and are utilized biochemically in the formation of ribonucleic acid (RNA).
