Rabbit lung prostaglandin omega-hydroxylase (P450 4A4) was expressed in Escherichia coli using the isopropyl beta-D-thiogalactopyranoside (IPTG) inducible expression vector pCWori+, containing the full-length cDNA encoding the P450 4A4. The first seven codons were changed to reflect E. coli codon bias [a modification of the method of Barnes et al. (1991)(More)
Mercury resistance shown by a strain of Enterobacter aerogenes was found to be determined by a plasmid. The resistance appeared to be not due to enzymatic volatilization of mercury, but due to the alteration in cellular permeability to mercury. Comparison of the outer membrane proteins was made between the resistant cells and the sensitive counterparts(More)
A gene subfamily of cytochromes P450 with catalytic activity toward various eicosanoid substrates has been studied with a variety of techniques in this laboratory, including purification and characterization, localization at the tissue and subcellular levels, physiological function, and cloning and expression in prokaryotic and eukaryotic systems.

12-Hydroxy-16-heptadecynoic acid has been shown to selectively inactivate cytochrome P450 4A4, a pulmonary cytochrome P450 enzyme that catalyzes the omega-hydroxylation of prostaglandins [Muerhoff, A. S.; Williams, D. E.; Reich, N. O.; CaJacob, C. A.; Ortiz de Montellano, P. R.; Masters, B. S. S. J. Biol. Chem. 1989, 264, 749-756]. Potent, specific(More)
