How about the human tRNA-IPT?

Deduction:

- a P-loop may exist

- P-loop pattern is not the same as adenylate kinase

Figure 13 2qor superimposed against 2qgn via PyMOL. 2qgn indicated in green

--> shows that the P-loop pattern is not same as guanylate kinase

- the structure might have diverged

- a zinc finger motif is found in human

--> Zn finger motifs are commonly found in nucleic acid binding

-- Previously in LOCATE found that human enzyme in nucleus

--> supports the nucliec binding properties of this enzyme
