Biosynthesis of keratan sulfate: Purification and properties of a galactosyltransferase from bovine cornea
(Elsevier, 1979-02)
A soluble galactosyltransferase was purified 22,000-fold from bovine cornea. The enzyme catalyzes the transfer of galactose from UDP-galactose to N-acetyl--glucosamine, [alpha]- and [beta]-glucosaminides, bovine cornea and ...
Steady-state measurements of respiration rate with an oxygen electrode
(Elsevier, 1975-02)
An oxygen electrode was developed which measures steady-state respiration rates in a volume of 0.25 ml and at oxygen concentrations as low as 0.1 [mu]. The steady state was achieved by pumping air-equilibrated buffer into ...
Cross-peptide bond 13C---15N coupling constants by 13C and J cross-polarization 15N NMR
(Elsevier, 1979-07)
Comparative 13C---15N coupling constants are reported for the linear dipeptide tBoc--[U-13C]Ala-[15N]GlyOMe and the corresponding cyclic diketopiperazine, both in dimethylsulfoxide (DMSO) and, upon removal of the tBoc ...
Studies on hydroperoxide-dependent substrate hydroxylation by purified liver microsomal cytochrome P-450
(Elsevier, 1976-08)
Highly purified liver microsomal cytochrome P-450 catalyzes the hydroperoxide-dependent hydroxylation of a variety of substrates in the absence of NADPH, NADPH-cytochrome P-450 reductase, and molecular oxygen. The addition ...
Characterization of the [omega]-hydroxylase of Pseudomonas oleovorans as a nonheme iron protein
(Elsevier, 1977-10)
The [omega]-hydroxylase of Pseudomonas oleovorans, which catalyzes the hydroxylation of fatty acids and alkanes and the epoxidation of alkenes in the presence of a reduced pyridine nucleotide, a reductase, rubredoxin, and ...
Mitochondrial inner membrane in hypothyroidism
(Elsevier, 1976-02)
Inner membrane vesicles obtained from the liver mitochondria of hypothyroid and normal rats were compared. In the vesicles from hypothyroid rats the rate of ATP synthesis at 30 [deg]C is 35-50% less than the normal rate. ...
Statistical survey of "saturation analysis" calibration curve data for prednisolone, prednisone and digoxin
(Elsevier, 1976-09)
An extensive survey of radioimmunoassay calibration data for prednisolone, prednisone and digoxin indicated that the common practice of preparing calibration curves with individual subject's pre-dose plasma or serum, and ...
The protective effects of dietary fish oil on focal cerebral infarction
(Elsevier, 1979-11)
The protective effect of the (n-3) fatty acids in menhaden fish oil on acute cerebral ischemia was investigated in cats. Cerebral ischemia was produced by ligation of the left middle cerebral artery of cats fed either a ...
The biosynthesis by brain microsomes of cerebrosides containing nonhydroxy fatty acids,
(Elsevier, 1970-12)
Incubation of microsomes from mouse brain with UDP-gal, a long-chain base, and 14C-fatty acyl-CoA resulted in formation of NFA-cerebroside labeled in the fatty acid residue. The rate of synthesis was ten times that of the ...
