The peptide antibiotic tyrocidine which is produced by Bacillus brevis and is probably involved in sporogenesis, unwinds superhelical plasmids in vitro at low peptide: DNA ratios, as found by gel electrophoresis. At higher peptide concentrations, the

We report on the effect of ethanol and acetaldehyde on yeast chromosomal DNA and on isolated DNA. Ethanol induced DNA single-strand breaks in repair deficient but not in repair proficient Saccharomyces cerevisiae. Acetaldehyde has a deleterious effec

Tyrocidine, a peptide antibiotic produced by Bacillus brevis (ATCC 8185), relaxes superhelical DNA in a biphasic manner and induces 'packaging' of the DNA at higher concentrations. This was concluded from studies using the sensitive 4,5',8-trimethylp

The peptide antibiotic tyrocidine affects transcription in vitro by interfering with the initiation process. The complex formed between tyrocidine and native DNA is stable against nucleolytic enzymes. It is sensitive to variations in the salt concent

Summary: Mutants of Bacillus brevis ATCC 8185 were isolated which were unable to produce detectable amounts of either tyrocidine or linear gramicidin, or both peptide antibiotics. Tyrocidine-negative mutants (BM5, BM21, BM44) sporulated normally. Gra

Transport of 2-aminoisobutyric acid in embryonic rat fibroblasts is mediated by a carrier system, Km, app.= 8 × 10−3 M. It was also shown by competition experiments with naturally occurring amino acids that the alanine carrier is responsible for 2

Alcohol is mutagenic, cancerogenic and teratogenic in man. Ethanol is mutagenic via its first metabolite, acetaldehyde. This is substantiated by the findings that acetaldehyde induces chromosomal aberrations, sister-chromatid exchanges and cross-link
