• guanine
  • dubious - discuss]Its structure is similar to that of the guanine nucleobase, the only difference being that nucleotides like GTP have a ribose sugar and three phosphates, with the nucleobase attached to the 1' and the triphosphate moiety attached to the 5' carbons of the ribose.

  • gene
  • RPMI-8226R was subjected to microarray gene expression profiling, and guanosine triphosphate (GTP) level was determined with the objective of comparing these biomarkers to the same markers in patient samples from the Phase I clinical trial. (thefreedictionary.com)
  • concentrations
  • Four triphosphates, XTP, ITP, 7-methyl-GTP and 2′-O-methyl-GTP, gave 50% inhibition of both the poly(C)- and poly(U2,C)-dependent reactions at concentrations from 0.1 to 5 mM. (biochemj.org)
  • ability
  • The current study demonstrates that the ability of guanosine 5'-triphosphate (GTP) and its nonhydrolyzable analogue guanylyl-5'-imidodiphosphate (Gpp(NH)p) to inhibit opiate agonist binding to rat brain membranes can be altered by two methods: by preincubating with EDTA, and by preincubating at pH 4.5.
