What is found?

Function of similar fold proteins Adenylate kinase and guanylate kinase= catalyzes the ATP-dependent phosphorylation of GMP into GDP.

Also found, adenylate and guanylate kinase have a P-loop structure

Description of P-loop: - formed between a β-strand and a α-helix - at its N-terminus
