Crystal structure of human indoleamine 2,3-dioxygenase: catalytic mechanism of O2 incorporation by a heme-containing dioxygenase.
Human indoleamine 2,3-dioxygenase (IDO) catalyzes the cleavage of the pyrrol ring of L-Trp and incorporates both atoms of a molecule of oxygen (O2). Here we report on the x-ray crystal structure ofExpand

Marked Potentiation of Activity of β-Lactams against Methicillin-Resistant Staphylococcus aureus by Corilagin
ABSTRACT We found that an extract of Arctostaphylos uva-ursimarkedly reduced the MICs of β-lactam antibiotics, such as oxacillin and cefmetazole, against methicillin-resistant Staphylococcus aureus.Expand

Heme oxygenase and heme degradation.
The microsomal heme oxygenase system consists of heme oxygenase (HO) and NADPH-cytochrome P450 reductase, and plays a key role in the physiological catabolism of heme which yields biliverdin, carbonExpand

Restoration of effectiveness of beta-lactams on methicillin-resistant Staphylococcus aureus by tellimagrandin I from rose red.
We found that extract from petals of Rosa canina L. (rose red) strikingly reduced the minimum inhibitory concentration of beta-lactams in methicillin-resistant Staphylococcus aureus. We isolated twoExpand
