Structure of the quinoline N-hydroxylating cytochrome P450 RauA, an essential enzyme that confers antibiotic activity on aurachin alkaloids

The Structure of the Antibiotic Deactivating, N-hydroxylating Rifampicin Monooxygenase.

Rifampicin monooxygenase (RIFMO) catalyzes the N-hydroxylation of the natural product antibiotic rifampicin (RIF) to 2'-N-hydroxy-4-oxo-rifampicin, a metabolite with much lower antimicrobial activity. RIFMO shares moderate sequence similarity with well characterized flavoprotein monooxygenases, but the protein has not been isolated and characterized at the molecular level. Herein, we report cry...

the structure of lie derivations on c*-algebras

نشان می دهیم که هر اشتقاق لی روی یک c^*-جبر به شکل استاندارد است، یعنی می تواند به طور یکتا به مجموع یک اشتقاق لی و یک اثر مرکز مقدار تجزیه شود. کلمات کلیدی: اشتقاق، اشتقاق لی، c^*-جبر.

Engineered alkane-hydroxylating cytochrome P450(BM3) exhibiting nativelike catalytic properties.

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

Cytochrome P450 species involved in the metabolism of quinoline.

Quinoline is a hepatocarcinogen in rats and mice and a well-known mutagen in bacteria after incubation with rat liver microsomes. The specific cytochrome P450 enzymes involved in quinoline metabolism in human and rat liver microsomes were determined using cDNA-expressed cytochrome P450s, correlations with specific cytochrome P450-linked monooxygenase activities in human liver microsomes and inh...
