Re: Why is ATP rather than GTP, CTP or TTP the energy currency?

... energy, and why don't ribosomes also catalyse the reverse reaction of peptide formation, now I guess it's due to the GTP hydrolysis? But I also ... ATP too? Secondly, almost all of them CTP-GTP-TTP and ATP have same Bond energy . All nucleoside triphosphates have ΔG°' values close to -31 ...
