Medical Definition of Guanosine tetraphosphate

1. Guanosine 5'-diphosphate 2'(3')-diphosphate. A guanine nucleotide containing four phosphate groups. Two phosphate groups are esterified to the sugar moiety in the 5' position and the other two in the 2' or 3' position. This nucleotide serves as a messenger to turn off the synthesis of ribosomal RNA when amino acids are not available for protein synthesis. Synonym: magic spot I. Chemical name: Guanosine 5'-(trihydrogen diphosphate), mono(trihydrogen diphosphate) (ester) (12 Dec 1998)
