Literature summary for 2.4.2.1 extracted from
- Remote mutations alter transition-state structure of human purine nucleoside phosphorylase (2008), Biochemistry, 47, 2565-2576.
Protein Variants
| Protein Variants | Comment | Organism |
|---|---|---|
| K22E/H104R | the transition state of the mutant is fully dissociative, N7-protonated hypoxanthine with C1'-N9 distance above 3.0 A, with partial participation of phosphate, C1-Ophosphate distance is 2.26 A, 2'-C-exo-ribosyl ring pucker and the O5'-C5'-C4'-O4' dihedral angle near 60°. The transition state of the mutant is altered from the fully dissociative DN*AN character for the human wild-type purine nucleoside phosphorylase to a late phosphate-associative character | Homo sapiens |
