WebHowever, after some time, tubulin molecules hydrolyze the GTP molecule to form guanosine diphosphate (GDP). This hydrolysis of GTP makes the binding to other tubulin molecules to the microtubule unfavorable. This results in depolymerization. This polymerization and depolymerization cycling provides microtubules with their dynamic nature. WebNov 28, 2008 · A GTP-remnant model for microtubule dynamic instability. (A) Model for microtubule dynamics showing GTP-tubulin (red) in a GTP cap during polymerization (P) and in inner microtubule regions. Upon cap loss, the probability of catastrophe (C) increases and the microtubule depolymerizes (D) until its end reaches a GTP-tubulin remnant.

GTP is involved in energy transfer within the cell. For instance, a GTP molecule is generated by one of the enzymes in the citric acid cycle. This is tantamount to the generation of one molecule of ATP, since GTP is readily converted to ATP with nucleoside-diphosphate kinase (NDK). During the elongation stage of translation, GTP is used as an energy source for the binding of a new amino-bound tRNA to the A site of the ribosome. GTP is also used as an energy source for t…
