Characterization of the guanosine 5'-triphosphate 3'-diphosphate and guanosine 5'-diphosphate 3'-diphosphate degradation reaction catalyzed by a specific pyrophosphorylase from Escherichia coli

Biochemistry, 1978
Guanosine 5'-triphosphate 3'-diphosphate (pppGpp) and guanosine 5'-diphosphate 3'-diphosphate (ppGpp) are specifically degraded by a manganese-dependent pyrophosphorylase present in spoT+ but not in spoT- strains of Escherichia coli, indicating that the enzyme is the spoT gene product.

5‘-RNA Self-Capping from Guanosine Diphosphate

Biochemistry, 1997
A selected RNA (isolate 6) efficiently catalyzes a self-capping reaction with free GDP, yielding the same 5'-capped structure as is formed by protein GTP:RNA guanylyltransferase. This unexplored RNA-catalyzed reaction type involving nucleophilic attack on phosphate by phosphate adds to the variety of possible postsynthetic RNA-catalyzed RNA ...

Selective Inhibition of tRNA^Tyr Transcription by Guanosine 3′‐Diphosphate 5′‐Diphosphate

European Journal of Biochemistry, 1977
Guanosine 3′‐diphosphate 5′‐diphosphate (ppGpp) selectively reduces the synthesis of su+III tRNA from θ80 psu+III DNA relative to the synthesis of θ80 RNA in a system in vitro containing DNA and Escherichia coli RNA polymerase holoenzyme as the sole macromolecular components.

Modulation of guanosine 5′-diphosphate-d-mannose metabolism in recombinant Escherichia coli for production of guanosine 5′-diphosphate-l-fucose

Bioresource Technology, 2009
Guanosine 5'-diphosphate (GDP)-L-fucose, an activated form of a nucleotide sugar, plays an important role in a wide range of biological functions. In this study, the enhancement of GDP-L-fucose production was attempted by supplementation of mannose, which is a potentially better carbon source to be converted into GDP-L-fucose than glucose, and ...

Nucleotide specificity of stringent factor and the synthesis of analogs of guanosine 5'-diphosphate 3'-diphosphate and guanosne 5'-triphosphate 3'-diphosphate

Biochemistry, 1975
The ribosome-dependent stringent factor reaction was found to be nonspecific with regard to the number of phosphate groups linked to the 5' position of guanosine nucleotides. Both GMP and guanosine 5'-tetraphosphate could accept a pyrophosphoryl group from ATP although at a much lower rate than GDP or GTP.

[107] Isolation of uridine diphosphate glucose, uridine diphosphate acetylglucosamine, and guanosine diphosphate mannose

1963
Publisher Summary This chapter describes the isolation of uridine diphosphate glucose, uridine diphosphate acetylglucosamine, and guanosine diphosphate mannose. The basic principle is that alcoholic extract from toluene-autolyzed yeast is fractionated on anion-exchange columns.
