guanosine monophosphate

guanosine /gua·no·sine/ (gwah´no-sēn) a purine nucleoside, guanine linked to ribose; it is a component of RNA and its nucleotides are important in metabolism. Symbol G.

cyclic guanosine monophosphate  3′,5′-GMP, cGMP, cyclic GMP; a cyclic nucleotide that acts as a second messenger similar in action to cyclic adenosine monophosphate but generally producing opposite effects on cell function.

guanosine monophosphate  (GMP) a nucleotide important in metabolism and RNA synthesis.

guanosine triphosphate  (GTP) an energy-rich compound involved in several metabolic reactions and an activated precursor in the synthesis of RNA.

guanosine monophosphate (GMP),

a nucleotide that plays an important role in various metabolic reactions and in the formation of RNA from DNA templates.

guanosine

a nucleoside, guanine riboside, one of the major constituents of nucleic acids.

cyclic guanosine monophosphate (cyclic GMP, cGMP)

a cyclic 3′,5′-phosphate that acts as an intercellular second messenger mediating the activity of hormones and other substances; essential in vision where cGMP concentrations increase in the dark.

guanosine monophosphate

a nucleotide important in metabolism and nucleic acid synthesis; called also GMP.

guanosine pentophosphate

involved with guanosinetetraphosphate in the so called stringent response of bacteria in which, because the cell does not have a sufficient pool of amino acids to maintain protein synthesis, tRNA and rRNA synthesis is reduced by about 20-fold, which suspends many of the cells' activities until conditions improve.

guanosine tetraphosphate

see guanosine pentophosphate (above).

guanosine triphosphate

an energy-rich compound involved in several metabolic reactions; called also GTP.
