Catalytic properties of the resolved flavoprotein and cytochrome B components of the NADPH dependent generating oxidase from human neutrophils
(Elsevier, 1984-01-30)
The resolved flavoprotein and cytochrome b559 components of the NADPH dependent generating oxidase from human neutrophils were the subject of further study. The resolved flavoprotein, depleted of cytochrome b559, was ...
Response of Solidago canadensis clones to competition
(Springer-Verlag, 1988-11)
Transplants of ten Solidago canadensis clones were grown under high and low competition in the field to determine whether clones differed in survival, growth, and reproduction under natural conditions. Transplants had ...
Microstructural studies of sputter-deposited TiN ceramic films
(Elsevier, 1989-05-02)
A transmission electron microscopy study was undertaken to characterize the microstructures of TiN thin films that were sputter-deposited onto Cu-Be, alumina and glass substrates. There were no substantial microstructural ...
Effects of streptozotocin-induced diabetes on feeding stimulated by centrally administered opioid agonists
(Elsevier, 1989)
The potencies of several opioid agonists are reduced in diabetic animals and in animals made hyperglycemic via injections of glucose. In this report we examined the effects of streptozotocin-induced diabetes on the feeding ...
Heteroplasmy of chloroplast DNA in Medicago
(Kluwer Academic Publishers; Springer Science+Business Media, 1989-01)
Two chloroplast DNA (cpDNA) regions exhibiting a high frequency of intra- or inter-species variation were identified in 12 accessions of the genus Medicago . Restriction maps of both regions were prepared for alfalfa, and ...
Properties of the tryptophan residue in rabbit liver microsomal cytochrome P-450 isozyme 2 as determined by fluorescence
(Elsevier, 1985-04-30)
Cytochrome P-450 isozyme 2 from rabbit liver microsomes fluoresces upon excitation at 295 nm due to the single tryptophyl residue (Trp121) in the protein. The fluorescence spectrum, which is not altered by the presence of ...
Resolution in the receptor binding of putative [mu] and [kappa] opiates
(Elsevier, 1984-05-28)
Conditions for the stereospecific binding of 3H-ethylketocyclazocine and 3H-etorphine were established in membranes from rat and pigeon brain. In displacing the specific binding of the radiolabeled ligands, putative [mu] ...
Benzoylarginine peptidase and iminopeptidase profiles of Treponema denticola strains isolated from the human periodontal pocket
(Springer-Verlag; Springer-Verlag New York Inc., 1986-03)
Seven clinical isolates and the ATCC strain 35405 of Treponema denticola , obtained from human periodontal pockets, were studied for peptidase activity with several chromogenic compounds as substrates. The cell sonicates ...
Cell proliferation-associated expression of a recently evolved isozyme of triosephosphate isomerase
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1985-04)
An electrophoretically unique, thermolabile isozyme of triosephosphate isomerase (TPI; EC 5.3.1.1) accounts for 10–30% of the enzymatic activity in a range of mitotically active human cells and tissues. This type 2 form ...
The mechanism of amine inhibition of the photosynthetic oxygen evolving complex : Amines displace functional chloride from a ligand site on manganese
(Elsevier, 1983-10-17)
Amines inhibit photosynthetic oxygen evolution by binding to manganese in the oxygen evolving complex. This inhibition is more effective if chloride is absent. Steady-state kinetic analyses show that ammonia and chloride ...
