6 Questions
Which enzyme catalyses the final step of the purine biosynthesis pathway?
Nucleoside-diphosphate kinase
How is GMP converted to GTP in the purine biosynthesis pathway?
By guanylate kinase
What is the role of nucleoside-diphosphate kinase in purine biosynthesis?
It converts NDPs to NTPs
What enzyme catalyzes the conversion of AMP to adenosine diphosphate in purine biosynthesis?
Adenylate kinase
How is GMP converted to GTP in the purine biosynthesis pathway?
Guanosine kinase to guanosine diphosphate, then nucleotide-diphosphate kinase to GTP
What is the role of nucleotide-diphosphate kinase in purine biosynthesis?
Catalyzes the production of NTPs from NDPs
