Analogues of uridine 5′‐diphosphate glucose and guanosine 5′‐diphosphate mannose

Recueil des Travaux Chimiques des Pays-Bas, 1990
AbstractOne‐pot coupling of 2′,3′‐di‐O‐benzoyl‐uridine and 4,5,6,8‐tetra‐O‐acetyl‐3,7‐anhydro‐2‐deoxy‐D‐glycero‐D‐ido‐octitol with appropriate bifunctional phosphoro‐, phosphono‐ and thiophosphonylation reagents gave, after removal of the base‐labile protecting groups, analogues of UDP‐Glc containing charged phosphate, neutral alkyl‐ and ...

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.

Intracellular levels of guanosine 5′-diphosphate 3′-diphosphate (ppGpp) and guanosine 5′-triphosphate 3′-diphosphate (pppGpp) in cultures of Streptomyces griseus producing streptomycin

Canadian Journal of Microbiology, 1978
Guanosine 5′-diphosphate 3′-diphosphate (ppGpp) and guanosine 5′-triphosphate 3′-diphosphate (pppGpp) were identified in the vegetative mycelium of Streptomyces griseus. Adenosine 5′-diphosphate 3′-diphosphate (ppApp) and adenosine 5′-triphosphate 3′-diphosphate (pppApp) were not present but several other phosphorus-containing compounds which may have

[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.

Microtubule assembly with the guanosine 5'-diphosphate analog 2',3'-dideoxyguanosine 5'-diphosphate

Biochemistry, 1983
The GDP analogue 2',2'-dideoxyguanosine 5'-diphosphate (ddGDP) supports efficient tubulin polymerization. Microtubule-associated protein (MAP) dependent microtubule assembly occurs in 0.1 M 2-(N-morpholino)-ethanesulfonate, and sheets of parallel protofilaments are formed in 1.0 M glutamate without MAPs. The nucleotide is bound to tubulin in the course

Effect of polyamines on synthesis and degradation of guanosine 5′-diphosphate 3′-diphosphate

Biochimica et Biophysica Acta (BBA) - General Subjects, 1983
The effect of polyamines on the in vitro and in vivo synthesis and degradation on guanosine 5'-diphosphate 3'-diphosphate (ppGpp) has been studied in Escherichia coli. The presence of 2 mM spermidine lowered the optimal Mg2+ concentration for ppGpp formation from 17 mM to 11 mM.

Is Guanosine Diphosphate-D-Glucose a Precursor of Cellulose ?

Nature, 1970
PARTICULATE enzyme preparations from bacteria1 and plants2,3 have been reported to catalyse the biosynthesis of high molecular weight β-1,4-linked glucan, chiefly cellulose, from either UDP-glucose or GDP-glucose. Partial hydrolysis of the polysaccharide formed from UDP-glucose, however, indicates the presence of β-1,3-linked glucose moieties4,5 ...
