Selective COX-2 inhibitors and risk of myocardial infarction [PDF]
Selective inhibitors of cyclooxygenase- 2 ( COX- 2, ` coxibs') are highly effective anti-inflammatory and analgesic drugs that exert their action by preventing the formation of prostanoids.

Effects of heme oxygenase isozymes on Leydig cells steroidogenesis [PDF]
In the present study, we demonstrate the expression of heme oxygenase (HO) isozymes, HO-1 and HO-2 (listed as HMOX1 and HMOX2 in the MGI Database), in MA-10 Leydig tumor cells and its effect on steroidogenesis. The well-known HO inducer, hemin, increased

Conservation of the unusual dimeric JmjC fold of JMJD7 from Drosophila melanogaster to humans
The JmjC family of 2-oxoglutarate dependent oxygenases catalyse a range of hydroxylation and demethylation reactions in humans and other animals. Jumonji domain-containing 7 (JMJD7) is a JmjC (3S)-lysyl-hydroxylase that catalyses the modification of ...

Strigolactone biosynthesis is evolutionarily conserved, regulated by phosphate starvation and contributes to resistance against phytopathogenic fungi in a moss, Physcomitrella patens [PDF]
In seed plants, strigolactones (SLs) regulate architecture and induce mycorrhizal symbiosis in response to environmental cues. SLs are formed by combined activity of the carotenoid cleavage dioxygenases (CCDs) 7 and 8 from 9-cis-β-carotene, leading to ...

ENGINEERING NON-HEME MONO- AND DIOXYGENASES FOR BIOCATALYSIS
Oxygenases are ubiquitous enzymes that catalyze the introduction of one or two oxygen atoms to unreactive chemical compounds. They require reduction equivalents from NADH or NADPH and comprise metal ions, metal ion complexes, or coenzymes in their active

Assays for the Detection of Rubber Oxygenase Activities
Microbial biodegradation of rubber relies on extracellular rubber oxygenases that catalyze the oxidative cleavage of the double bond of the polyisoprene backbone into oligo-isoprenoids.

Spin-orbit coupling effects in O(2) activation by cofactor-independent 2,4-dioxygenase [PDF]
The O2 (dioxygen) is paramagnetic molecule with two non-paired electron spins and triplet ground state (S = 1) while majority of organic molecules are diamagnetic species; they have all electron spins paired and the singlet ground state with the total ...

(Per)chlorate-reducing bacteria can utilize aerobic and anaerobic pathways of aromatic degradation with (per)chlorate as an electron acceptor. [PDF]
UnlabelledThe pathways involved in aromatic compound oxidation under perchlorate and chlorate [collectively known as (per)chlorate]-reducing conditions are poorly understood.

The specificity of cysteamine oxygenase
Oxidation of cysteamine to hypotaurine is catalyzed by cysteamine oxygenase (EC 1.13.11.19), a non-heme iron enzyme of large distribution [l-3] . A similar oxidation of cysteine to cysteine sulfinic acid has been reported to require a different oxygenase [4,.5]. Specificity of cysteamine oxygenase has been studied earlier in this laboratory by assaying

Structural basis for divergent C–H hydroxylation selectivity in two Rieske oxygenases
Rieske oxygenases are iron-dependent enzymes that catalyse C–H mono- and dihydroxylation reactions. Here, the authors characterise two cyanobacterial Rieske oxygenases, SxtT and GxtA that are involved in the biosynthesis of paralytic shellfish toxins and
