title: Substrate, substrate analogue, and inhibitor interactions with the ferrous active site of catechol 2,3-dioxygenase monitored through XAS studies.
abstract: The interactions of catechol (substrate), 2-hydroxy-pyridine-N-oxide (substrate analogue), and 2-bromophenol (inhibitor) with the extradiol cleaving catechol-2,3-dioxygenase from Pseudomonas putida mt-2 have been monitored through X-ray absorption spectroscopy (XAS). The analysis of the data provides details about the mode of coordination of the substrate and of the inhibitors to the active site of the enzyme.
