Further biochemical studies on aminopyrrolnitrin oxygenase (PrnD)

Bioorg Med Chem Lett. 2011 May 15;21(10):2873-6. doi: 10.1016/j.bmcl.2011.03.087. Epub 2011 Mar 30.

Abstract

Active site modeling of dimerization interface in combination with site-directed mutagenesis indicates that the electron in the PrnD Rieske oxygenase can be transferred by either of two pathways, one involving Asp183' and the other involving Asn180'. In addition, the overexpression of the isc operon involved in the assembly of iron-sulfur clusters increased the catalytic activity of PrnD in Escherichia coli by a factor of at least 4.
