Why do G proteins such as Ras use GTP rather than ATP?
Why is GTP used in cell signalling rather than ATP?
I understand thatG proteins such as Ras use GTP in cell signalling. Is there a reason why they don't use ATP instead? Can anyone throw any light on this? Thanks very much indeed for taking the time to respond.
