From Interpro
Function of isopentenyltransferase = synthesizes isopentenyladensosine 5'-monophosphate
Function of adenylate kinase and guanylate kinase= catalyzes the ATP-dependent phosphorylation of GMP into GDP
Also,
-found a P-loop pattern in adenylate kinase and guanylate kinase
-P-loop is said to be involved in ATP/GTP binding
Since there is a fold similarity between adenylate kinase and 2qgn, P-loop might be present.
Adenylate kinase --> P-loop motif is formed between a β-strand and a α-helix, at its N-terminus.
From PDB and Profunc,
- ligand interacts with AVGKT at position 775-780
- This is towards the end-terminus of the protein sequence and
- This sequence is between a β-strand and a α-helix (PDBsum)
Guanylate kinase has a P-loop as well but different pattern from adenylate kinase.
- Divergence of the P-loop motif
This accounts for the fact that 2qgn cannot be superimposed onto guanylate kinase
