Digestion patterns of chromosomal DNAs of Bacillus cereus and Bacillus weihenstephanensis strains suggest that Sau3AI-type restriction modification systems are widely present among the isolates tested. In vitro methylation of plasmid DNA was used to enhance poor plasmid transfer upon electroporation to recalcitrant strains that carry Sau3AI restriction barriers.

Leptin and leptin receptor genes are considered as production traits markers in dairy or beef cattle. The aim of this study was to verify the associations of polymorphisms in bovine LEP and LEPR genes with production and reproduction traits in Slovak Spotted and Pinzgau cows. Long-life production was evaluated: milk, protein, and fat yield and reproduction traits: age at first calving, calving ...

Sau3AI is a type II restriction endonuclease that recognizes the palindromic sequence 5'-GATC-3' and cleaves 5' to G residue on each strand. The E64A mutant full length protein was cloned and expressed in Escherichia coli. The purified (His) (6)-tagged protein has monomer and dimer fraction and was crystallized by the hanging-drop vapor-diffusion technique. The dimer protein crystals can diffra...

salmonella enterica is considered as one of the major pathogens in public health, worldwide. diseases caused by salmonella enterica serovars are especially prevalent in developing countries. it is one of the emerging pathogen in food-borne diseases, which is often found in contaminated chicken eggs. the aim of this study was to apply a pcr–rflp method using sau3ai and hhai restriction endonucle...

Salmonella enterica is considered as one of the major pathogens in public health, worldwide. Diseases caused by Salmonella enterica serovars are especially prevalent in developing countries. It is one of the emerging pathogen in food-borne diseases, which is often found in contaminated chicken eggs. The aim of this study was to apply a PCR–RFLP method using Sau3AI and HhaI restriction endonucle...

A new method was developed to detect DNA methylation in the Citrus genome using random amplification coupled with restriction enzyme digestion. Genomic DNA from Citrus grandis (L.) Osb., Poncirus trifoliata (L.) Raf., and their F1 hybrid was amplified using 7 individual 10-mer random primers. Prior to amplification the DNA templates were digested with 2 pairs of restriction endonucleases (HpaII...

A real-time PCR assay was developed for rapid detection of eubacterial 16S ribosomal DNA in platelet concentrates. The sensitivity of this assay can be hampered by contaminating DNA in the PCR reagents. Digestion of the PCR reagents with Sau3AI prior to PCR amplification was effective in eliminating this contaminating DNA without affecting the sensitivity of the assay.

A total of 181 Jersey cows were used to investigate how leptin gene polymorphisms affect somatic cell count (SCC) in milk. Three single nucleotide polymorphisms were genotyped, namely the R4C polymorphism in exon 2, the Sau3AI polymorphism in intron 2 and the A59V polymorphism in exon 3. The genotype and allele frequencies for each polymorphism and the haplotype frequencies for all polymorphism...

Restriction analysis of plasmid pHV14 deoxyribonucleic acid isolated from Escherichia coli K-12, Bacillus subtilis, and staphylococcus aureus with restriction endonucleases MboI, Sau3AI, and EcoRII was used to study the methylation of those nucleotide sequences which in E. coli contain the major portions of N6-methyladenine and 5-methylcytosine. The results showed that neither B. subtilis nor S...

The C-terminal 232-419 amino acids fragment of endonuclease Sau3AI has been successfully expressed in Escherichia coli with 6 His at its N-terminal. After purification and crystallization, one completed 2.8 A data set was collected using a Rigaku R-AXIS IV++ diffractometer. The plate-like crystals belong to orthorhombic space group P2(1)2(1)2(1) with the cell dimension of a = 34.75, b = 76.82, ...
