The experiment of model soil columns was performed in order to assess the functional diversity changes of soil microbial communities and enzymatic activity under the conditions of critical heavy metals (Pb, Zn and Cu) accumulation. The extremely high

Two additional conserved motifs (CM), CM Is and CM III, have been found in addition to well-known CM I and CM II within the primary amino acid sequences of almost all m6A- and m4C-methyltransferases (MTases). The boundaries of all four CM were define

The genes coding for the MunI restriction-modification (R-M) system, which recognize the sequence 5'-CAATTG, have been cloned and expressed in Escherichia coli, and their nucleotide sequences have been determined. The restriction endonuclease (ENase;

The complete type-II Cfr9I restriction-modification (R-M) system of Citrobacter freundii strain RFL9, recognizing the DNA sequence CCCGGG, has been cloned and expressed, and functionally active enzymes have been produced in Escherichia coli. Both the

The specificity of three DNA methyltransferases M.Alw26I, M.Eco31I and M.Esp3I, isolated from Acinetobacter Iwoffi RFL26, Escherichia coli RFL31 and Hafnia alvei RFL3+, respectively, was determined. All the enzymes methylate both strands of asymmetri

A 6.3 kb fragment of E.coli RFL57 DNA coding for the type IV restriction-modification system Eco57I was cloned and expressed in E.coli RR1. A 5775 bp region of the cloned fragment was sequenced which contains three open reading frames (ORF). The meth
