Muscarinic stimulation of phospholipid turnover in dissociated avian salt gland cells
(Elsevier, 1983-05-02)
Addition of carbamylcholine to 32P-prelabeled dissociated avian salt gland cells resulted in increased turnover of phosphatidic acid, phosphatidylinositol, phosphatidylinositol 4-phosphate and phosphatidylinositol ...
Rabbit nasal cytochrome P-450 NMa has high activity as a nicotine oxidase
(Elsevier, 1990-01-30)
Rabbit nasal olfactory and respiratory microsomes demonstrate high activity toward [3H]-(S)-nicotine, with specific activities of 22.2 and 6.5 nmol/min/mg protein, respectively. The major metabolite produced is (S)-nicotine ...
Amino-terminal sequence of phenobarbital-inducible cytochrome P-450 from rabbit liver microsomes: Similarity to hydrophobic amino-terminal segments of preproteins
(Elsevier, 1977-08-08)
SummaryThe amino-terminal sequence of two electrophoretically homogeneous forms of rabbit liver microsomal cytochrome P-450, P-450LM2 and P-45LM4, has been examined by automated Edman degradation. Methionine is the amino ...
Tetraphenylborate stimulation of phospholipid labeling in goldfish brain
(Elsevier, 1969-05-08)
The presence of tetraphenylborate (TPB, 10-3 M to 10-4 M) in goldfish brain particulate preparations during a 5-15 min incubation with [gamma]-32P-ATP or [gamma]-33P-ATP results in marked stimulation of labeling of ...
Fluorescence-based biosensing of zinc using carbonic anhydrase
(Kluwer Academic Publishers; Springer Science+Business Media, 2001-09)
Measurement of free zinc levels and imaging of zinc fluxes remains technically difficult due to low levels and the presence of interfering cations such as Mg and Ca. We have developed a series of fluorescent zinc indicators ...
Binding of yeast TFIIIC to tRNA gene bipartite internal promoters: Analysis of physical effects on the intervening DNA
(Elsevier, 1991-04-30)
Complexes between transcription factor TFIIIC and eukaryotic tRNA gene internal promoter A and B boxes are unusual in that the binding to the two distinct sites tolerates considerable variation in both distance and helical ...
Band-selective hetero- and homonuclear cross-polarization using trains of shaped pulses
(ESCOM Science Publishers B.V., Leiden/Kluwer Academic Publishers; ESCOM Science Publishers B.V. ; Springer Science+Business Media, 1996-09)
The performance of solution cross-polarization using trains of shaped pulses on two channels is investigated by computer simulation and experiment. It is determined that a Waltz modulation pattern of Gaussian pulses of ...
Bilirubin binding to myelin basic protein, histones and its inhibition in vitro of cerebellar protein synthesis
(Elsevier, 1974-06-18)
SummaryThe binding of unconjugated bilirubin to bovine CNS myelin basic protein and to lysine and arginine rich histones has been demonstrated by means of difference spectroscopy and circular dichroism spectroscopy. This ...
Acyl dihydroxyacetone phosphate: Precursor of alkyl ethers
(Elsevier, 1970-06-25)
1-0-Alkyl dihydroxyacetone phosphate is biosynthesized in guinea pig liver mitochondria and in rat brain microsomes by direct reaction of a long chain alcohol and acyl dihydroxyacetone phosphate. ATP and Mg++ are stimulatory ...
