4-Nitrocatechol (4NC) is a known inhibitor of lipoxygenase. This work presents the X-ray structure of soybean lipoxygenase-3 in complex with 4NC refined at 2.15 A resolution. The X-ray analysis shows 4NC near iron with partial occupancy, blocking access to Fe

Microbial degradation studies have pointed toward the occurrence of two distinct PNP catabolic pathways in Gram positive and Gram negative bacteria. The former involves 4-nitrocatechol (4-NC), 1,2,4-benzenetriol (BT), and maleylacetate (MA) as major degradation intermediates, whereas the later proceeds via

We report the structures of three intermediates in the O2 activation and insertion reactions of an extradiol ring-cleaving dioxygenase. A crystal of Fe2+-containing homoprotocatechuate 2,3-dioxygenase was soaked in the slow substrate 4-nitrocatechol in a low O2 atmosphere. The x-ray crystal

A 9.2-kb DNA fragment encoding the enzymes of a p-nitrophenol (PNP) catabolic pathway from Pseudomonas putida DLL-E4 was cloned and sequenced. Ten open reading frames (ORFs) were found and five ORFs were functionally verified. The pnpA and pnpC gene products
