1.14.13.166 evolution PNP monooxygenase belongs to a two-component flavin-diffusible monooxygenase family -, 745126 1.14.13.166 metabolism the enzyme PNP monoxygenase is involved in the degradation of 4-nitrophenol, proposed pathway, overview. 4-Nitrophenol is converted to 4-nitrocatechol by a 4-nitrophenol 2-monooxygenase, EC 1.14.13.29, of the enzyme, which is subsequently converted to 2-hydroxy-1,4-benzoquinone, EC 1.14.13.166 -, 745126 1.14.13.166 additional information enzyme structure homology model for PNP monooxygenase using crystal structure of chlorophenol 4-monooxygenase from Burkholderia cepacia AC1100, PDB IS 3HWC, as template. Molecular dynamics simulations performed for docking complexes show the stable interaction between enzyme and substrate 4-nitrocatechol. Docking of substrates into the active site of PNP monooxygenase, Arg100, Gln158 and Thr193 are the key catalytic residues, overview -, 745126 1.14.13.166 additional information enzyme structure homology model for PNP monooxygenase using crystal structure of chlorophenol 4-monooxygenase from Burkholderia cepacia AC1100, PDB IS 3HWC, as template.
