  1. Chemical and physical characterization of four interfacial-active rhamnolipids from Pseudomonas spec. DSM 2874 grown on n-alkanes.

    Zeitschrift fur Naturforschung. Section C. Bios... 40(1-2):51 (1985) PMID 3993180

    Four extracellular glycolipids produced under growth-limiting conditions were isolated from the culture broth of Pseudomonas spec. DSM 2874. After purification by column and thick-layer chromatography they were identified as anionic rhamnolipids. 1H and 13C-NMR studies showed that two of these, ...
  2. A disappearance of a 24-kDa acid-soluble protein from liver chromatin of normal and starved hens following D-galactosamine administration.

    Zeitschrift fur Naturforschung. Section C. Bios... 40(11-12):798 (1985) PMID 2421496

    Normal and starved adult chickens were injected intraperitoneally with D-galactosamine hydrochloride (0.5 g/kg body weight) and 6 h later liver chromatin acid-soluble proteins were isolated. These proteins were resolved by a two-dimensional polyacrylamide gel electrophoresis in the presence of n...
  3. Phosphorylation of coformycin and 2'-deoxycoformycin, and substrate and inhibitor properties of the nucleosides and nucleotides in several enzyme systems.

    Zeitschrift fur Naturforschung. Section C. Bios... 40(9-10):710 (1985) PMID 3002059

    Under conditions where 2'-deoxycoformycin is enzymatically phosphorylated by wheat shoot phosphotransferase to the 5'-phosphate in 15-20% yield, coformycin is a relatively poor substrate, and is phosphorylated only to the extent of less than or equal to 5%. However, chemical phosphorylation of c...
  4. On the role of branched-chain amino acids in protein turnover of skeletal muscle. Studies in vivo with L-norleucine.

    Zeitschrift fur Naturforschung. Section C. Bios... 40(5-6):427 (1985) PMID 3895764

    The effect of L-norleucine, an isomer of leucine, on protein metabolism in vivo was studied in suckling rats. Rats were injected subcutaneously with various doses of L-norleucine (0.5 and 5.0 mumol/g body wt.) every 12 h from 3 to 15 days post partum. Protein concentration, amino acid concentrat...
  5. Acyl chain specificity and kinetic properties of phospholipase A1 and A2 of bone marrow-derived macrophages.

    Zeitschrift fur Naturforschung. Section C. Bios... 40(5-6):356 (1985) PMID 4024704

    The fatty acyl specificity of phospholipase A1 and A2 in homogenates of mouse bone marrow-derived macrophages was determined using phosphatidylcholine and phosphatidylethanolamine of different acyl chain composition. Phosphatidylcholine with arachidonoyl at position 2 was cleaved preferentially ...
  6. Biochemical oxygen activation as the basis for the physiological action of tetrachlorodecaoxide (TCDO).

    Zeitschrift fur Naturforschung. Section C. Bios... 40(5-6):409 (1985) PMID 3839616

    Oxidation of methionine, 4-(methylthio)-2-oxobutyric acid (KMB), or 1-aminocyclopropane carbonic acid (ACC) are indicator reactions for activated oxygen species such as singlet oxygen (1O2), OH.-radical like oxidants, superoxide anion (O2.-), hydrogen peroxide (H2O2) or activated hemo-iron compl...
  7. Isolation of labeled lipoprotein from Escherichia coli and Proteus mirabilis after incubation with [14C]penicillin.

    Zeitschrift fur Naturforschung. Section C. Bios... 40(5-6):415 (1985) PMID 3895763

    [14C]penicillin binding experiments and membrane analysis were carried out with cell envelope preparations from Escherichia coli and Proteus mirabilis. After incubation with [14C]penicillin G labeled free lipoprotein could be identified. The analysis of the isolated lipoprotein by SDS polyacryla...
  8. Localization of chromenes and benzofurans in the genus Encelia (Asteraceae).

    Zeitschrift fur Naturforschung. Section C. Bios... 40(5-6):301 (1985) PMID 4024703

    Phytochemical and microscopial analysis of leaves and stems of various species of Encelia showed a strict correlation between the presence of resin ducts and the accumulation of benzopyrans and benzofurans. Fluorescence microscopy of Encelia farinosa proved unambigously that these compounds are ...
  9. Small-angle X-ray and light scattering studies on the influence of Mg2+ ions on the structure of the RNA from bacteriophage MS2.

    Zeitschrift fur Naturforschung. Section C. Bios... 40(3-4):234 (1985) PMID 4002831

    The influence of Mg2+ ions on the secondary and tertiary structure of the RNA from bacteriophage MS2 was investigated by small-angle X-ray scattering and light scattering and by sedimentation experiments. The analysis of the outer part of the X-ray scattering curve obtained at low temperature in...
  10. Site of H atom attack on uracil and its derivatives in aqueous solution.

    Zeitschrift fur Naturforschung. Section C. Bios... 40(3-4):292 (1985) PMID 4002833

    Hydrogen atoms from the radiolysis of water at pH 1.6 add to the 5,6-double bond of pyrimidines. The preferential site of attack is the C(5) position (values in brackets) in the case of 6-methyluracil (87%), 1,3-dimethyluracil (71%), uracil (69%) and poly(U) (60%). This reaction yields a radical...
