A functional role for a protein cavity that stabilizes inhibitor binding has been established based on a comparison of Xe-derivatized and inhibitor-bound X-ray crystal structures in dehaloperoxidase-hemoglobin (DHP A) of Amphitrite ornata. The internal binding affinity of four different inhibitors,
Bromophenols (BPs) are important organic compounds which have become dominant pollutants during these years. Our present study investigated the potential inhibition behaviour of BPs on the activity of one of the most important phase II drug-metabolizing enzymes (DMEs), UDP-glucuronosyltransferases
Dehaloperoxidase (DHP A), a unique multifunctional enzyme, from the marine annelid Amphitrite ornata dehalogenates 2,4,6-tribromophenol to form 2,6-dibromo-1,4-benzoquinone. The catalytic cycle of DHP is similar to that of horseradish peroxidase (HRP), involving a high-valent ferryl heme and two
The T-shaped host molecule 4,4-bis(4'-hydroxyphenyl)cyclohexanone (1) has an equatorial phenol group and a cyclohexanone group along the arms and an axial phenol ring as the stem. The equatorial phenyl ring adopts a "shut" or "open" conformation, like a windowpane, depending on the size of the guest
Halogenated phenols, such as 2,4-dichlorophenol (2,4-DCP) and 4-bromophenol (4-BP) are pollutants generated by a various industrial sectors like chemical, dye, paper bleaching, pharmaceuticals or in an agriculture as pesticides. The use of Horseradish peroxidase (HRP) in the halogenated phenols
OBJECTIVE
To evaluate the staining characteristics and safety of potential new dyes for intraocular surgery in porcine eyes.
METHODS
Four dyes in different solutions (light green SF yellowish [LGSF]: 2%; copper(II) phthalocyanine-tetrasulfonic acid [E68]: 2% and 0.5%; bromophenol blue [BPB]: 2%, 1%,
In the adult palm squirrel, F. pennanti the pineal is a club shaped, elongated structure with a connective tissue capsule. It consists of various types of pinealocytes, glial cells, neurons, nerve fibres, blood vessels and connective tissue. Two types of pinealocytes could be identified by light
The four-component toluene/o-xylene monooxygenase (ToMO) from Pseudomonas stutzeri OX1 is capable of oxidizing arenes, alkenes, and haloalkanes at a carboxylate-bridged diiron center similar to that of soluble methane monooxygenase (sMMO). The remarkable variety of substrates accommodated by ToMO
Herein, we present photoacoustic calorimetry and transient absorption studies of the dynamics and energetics associated with dissociation of a ligand from Fe(2+) dehaloperoxidase (DHP) from Amphitrite ornata. Our data show that CO photodissociation is associated with an endothermic (DeltaH = 8 +/- 3
A histological and histochemical study was performed in the buccal cavity and papillae, which were around the teeth, as well as in the oesophagus and oesogaster of the Senegal sole, Solea senegalensis adult specimens. The oesophagus and oesogaster were made up of four distinct layers: mucosa,
OBJECTIVE
To evaluate and compare the effects of the following dyes on human pigmented epithelial cells: indocyanine green (ICG), infracyanine green (IfCG), trypan blue (TB), bromophenol blue (BrB), patent blue (PB), and Brilliant Blue G (BBG).
METHODS
ARPE-19 cells cultured in vitro were exposed to
