Journal ArticleDOI
DNA methylationin normal and tumour virus-transformed cells in tissue culture I. The level of DNA methylation in BHK21 cells and in BHK21 cells transformed by polyoma virus (PyY cells)
TL;DR: The possibility that the level of 5-methylcytosine in DNA in mammalian cells could alter with their rate of DNA synthesis, or their degree of contact inhibition, was investigated by synchronising the cells with deoxyadenosine.
Journal ArticleDOI
Regulation of gene expression by photosynthetic signals triggered through modified CO2 availability
Dennis Wormuth,Margarete Baier,Andrea Kandlbinder,Renate Scheibe,Wolfram Hartung,Karl-Josef Dietz +5 more
TL;DR: In the mutants, signalling pathways are partially uncoupled, demonstrating dominance of metabolic control of photoreaction centre expression over sensing the redox state of the PQ-pool.
Journal ArticleDOI
Effect of selected essential oils and pure compounds on Saprolegnia parasitica
TL;DR: The activity of some essential oils are compared with the activity of their isolated chemical constituents to evaluate molecular classes active against S. parasitica and the acyclic mono- and sesquiterpenic primary alcohols and aldehydes seem to be the most active compounds.
Journal ArticleDOI
Photosynthetic reactions with pyridine nucleotide analogs: II. 3-pyridinealdehyde-diphosphopyridine nucleotide and 3-pyridinealdehyde-deamino-diphosphopyridine nucleotide
TL;DR: In this paper, it was shown that a substituted pyridine ring with a quaternary N-atom is necessary for catalytic activity in photophosphorylation with spinach chloroplast fragments.

TL;DR: It is suggested that alginate which is very similar to plant pectate is required for establishing bacterial infections in later disease stages, and this concept was confirmed by evaluating transposon mutants with EPS deficiencies.

Allgemeine Charakterisierung eines Enzyms
TL;DR: In this article, a physiologischer Vorgang auf eine enzymatische Wirkung zuruckgefuhrt werden (vgl. S. 301), besteht die folgende Aufgabe darin, Naheres uber die Eigenschaften des beteiligten Enzyms zu ermitteln.
Book ChapterDOI
Optical Rotatory Dispersion. Its Application to Protein Conformation.
E. F. Woods,Donnell +1 more
TL;DR: Optical rotation has been found to be one of the most convenient methods of following the denaturation of proteins and rotatory dispersion is capable of providing information on the folding of the polypeptide chain in proteins and the changes accompanying denaturation.
