Guanosine-5'-triphosphate (GTP) is a purine nucleoside triphosphate. It is one of the building blocks needed for the synthesis of RNA during the transcription process. Its structure is similar to that of the guanosine nucleoside, the only difference being that nucleotides like GTP have phosphates on their ribose sugar. GTP has the guanine nucleobase attached to the 1' carbon of the ribose and it … WebSep 25, 2012 · The central paradigm of microtubule biology is that microtubules are stabilized by a ‘GTP cap’, a region at the end of a polymerizing microtubule where GTP …
