Interaction of linear manno-oligosaccharides with three mannose-specific bulb lectins. Comparison with mannose/glucose-binding lectins
(Elsevier, 1992-05-22)
Three new mannose-binding lectins, isolated from daffodil (NPA), amaryllis (HHA), and snowdrop (GNA) bulbs, are capable of precipitating with a linear mannopentaose (Man[alpha]1-3Man[alpha]1-3Man[alpha]1-3Man[alpha]1-2Man). ...
A dual function activity-dependent, muscle-specific enhancer from rat nicotinic acetylcholine receptor δ-subunit gene
(John Wiley & Sons, Inc., 1996-11)
Nicotinic acetylcholine receptors (nAChR) mediate communication between nerve and muscle. The expression of these receptors increases dramatically during muscle development when myoblasts are fusing into multinucleated ...
Interaction of five -mannose-specific lectins with a series of synthetic branched trisaccharides
(Elsevier, 1991-06-25)
The interaction of a series of synthetic, branched trisaccharides with five -mannose-specific lectins was studied by precipitation-inhibition assay. The branched methyl [alpha]--mannotrioside, [alpha]--Manp-(1-->3)-[[ ...
cDNA and derived amino acid sequence of rabbit nasal cytochrome P450NMb (P450IIG1), a unique isozyme possibly involved in olfaction
(Elsevier, 1991-02-15)
Olfactory-specific cytochrome P450NMb was previously purified to electrophoretic homogeneity from microsomes of rabbit nasal mucosa in this laboratory. In the present study, a cDNA library made from poly(A)+ RNA from rabbit ...
Detection of intermediate protein conformations by room temperature tryptophan phosphorescence spectroscopy during denaturation of Escherichia coli alkaline phosphatase
(Elsevier, 1993-12)
The reversible denaturation of Escherichia coli alkaline phosphatase (AP) was followed by monitoring changes in enzymatic activity as well as by measurements of the time-resolved room temperature phosphorescence from Trp ...
Coupling of dihydroriboflavin oxidation to the formation of the higher valence states of hemeproteins
(Elsevier, 1991-11-27)
SummaryThe reactions between hydrogen peroxide and hemeproteins have been coupled to the oxidation of dihydroriboflavin so as to provide a simple method for measuring the rate constant of hemeprotein peroxidation. ...
Protection by Vitamin B 2 Against Oxidant-Mediated Acute Lung Injury
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1999-10)
The effect of vitamin B 2 (riboflavin) on oxidant-mediated acute lung injury has been examined in three different rat models. Pulmonary injury was induced by intravenous injection of cobra venom factor (CVF), by the ...
Structure-function analysis in nuclear RNase P RNA
(Kluwer Academic Publishers; Springer Science+Business Media, 1995-06)
Eukaryotic ribonuclease P (RNase P) enzymes require both RNA and protein subunits for activity in vivo and in vitro . We have undertaken an analysis of the complex RNA subunit of the nuclear holoenzyme in an effort to ...
Role for calcium from the sarcoplasmic reticulum in coupling muscle activity to nicotinic acetylcholine receptor gene expression in rat
(John Wiley & Sons, Inc., 1998-06-05)
Neurally evoked muscle electrical activity suppresses nicotinic acetylcholine receptor (nAChR) gene expression in extrajunctional domains of adult muscle fibers. It has been proposed that this regulation is mediated by ...
Determination of the electro-optical coefficient r33 and refractive index of para-substituted poly([gamma]-benzyl--glutamate) derivatives
(Elsevier, 1994-01)
The electro-optical coefficient r33 and refractive index of films of poly([gamma]-benzyl--glutamate) and the p-nitro, p-fluoro and p-trifluoromethyl derivatives were determined as a way to assess the non-linear optical ...
