Cloning and characterization of the MboII restriction-modification system.
The two genes encoding the class IIS restriction-modification system MboII from Moraxella bovis were cloned separately in two compatible plasmids and expressed in E. coli RR1 delta M15. The nucleotide sequences of the MboII endonuclease (R.MboII) and methylase (M.MboII) genes were determined and the putative start codon of R.MboII was confirmed by amino acid sequence analysis. The mboIIR gene s...
متن کاملCloning the BamHI restriction modification system.
BamHI, a Type II restriction modification system from Bacillus amyloliquefaciensH recognizes the sequence GGATCC. The methylase and endonuclease genes have been cloned into E. coli in separate steps; the clone is able to restrict unmodified phage. Although within the clone the methylase and endonuclease genes are present on the same pACYC184 vector, the system can be maintained in E. coli only ...
متن کاملCloning and analysis of the genes encoding the type IIS restriction-modification system HphI from Haemophilus parahaemolyticus.
The genomic region encoding the type IIS restriction-modification (R-M) system HphI (enzymes recognizing the asymmetric sequence 5'-GGTGA-3'/5'-TCACC-3') from Haemophilus parahaemolyticus were cloned into Escherichia coli and sequenced. Sequence analysis of the R-M HphI system revealed three adjacent genes aligned in the same orientation: a cytosine 5 methyltransferase (gene hphIMC), an adenine...
متن کاملCloning and expression of the BalI restriction-modification system.
BalI, a type II restriction-modification (R-M) system from the bacterium, Brevibacterium albidum, recognizes the DNA sequence 5'-TGGCCA-3'. We cloned the genes encoding the BalI restriction endonuclease and methyltransferase and expressed them in Escherichia coli. The two genes were aligned tail-to-tail and their termination codons overlapped. BalI restriction endonuclease and methyltransferase...
متن کاملStepwise cloning and molecular characterization of the HgiDI restriction-modification system from Herpetosiphon giganteus Hpa2.
The restriction-modification system HgiDI from Herpetosiphon giganteus strain Hpa2 has been cloned in E. coli in a two-step procedure. Selection of the methyltransferase (M.HgiDI) gene in vitro was performed using the heterologous restriction endonuclease AhaII, an isoschizomer of Acyl and HgiDI (GRCGYC). Cloning of the complete HgiDI endonuclease (R.HgiDI) gene could only be achieved in recipi...
