Many cellular enzymes are regulated by the noncovalent binding of GTP and GDP, such that they are active when GTP is bound but inactive when GDP is bound. What are the differences between these nucleotides and how might they affect enzyme activity?
Added by Stephanie W.
Step 1
GTP and GDP are both nucleotides, but they differ in the number of phosphate groups they contain. GTP has three phosphate groups, while GDP has two phosphate groups. Show more…
