modified nucleotides

Post by biology_is_power » Sun Mar 05, 2006 8:07 am

greetings:

i know that ATP is a modified nucleotide that plays an important role in energy metabolism, but are there any more that are crucial?

Thanks

Yes. GTP for instance.

ATP = Adenosine Triphosphate. Adenine (purine base) can turn into adenonsine (a nucleoside) which then can turn into ATP (a nucleotide)

ATP, CTP, GTP etc

Hope this tidbit helps.

also nucleotides in tRNA-molecules for instance are modified (recall that pseudo-uridine is also 1 of many modified nucleic acids)
