One recognition sequence, seven restriction enzymes, five reaction mechanisms.

The diversity of reaction mechanisms employed by Type II restriction enzymes was investigated by analysing the reactions of seven endonucleases at the same DNA sequence. NarI, KasI, Mly113I, SfoI, EgeI, EheI and BbeI cleave DNA at several different positions in the sequence 5'-GGCGCC-3'. Their reactions on plasmids with one or two copies of this sequence revealed five distinct mechanisms. These...

Restriction Enzyme Recognition Sequence

A critical and difficult part of characterizing restriction enzymes and methylases is the identification of recognition sequences. To simplify this process, we have developed a plasmid transformation method along with a computer program named RM search that determines the exact recognition sequences for given restriction and modifica-

Structural insights into DNA sequence recognition by Type ISP restriction-modification enzymes

Engineering restriction enzymes with new sequence specificity has been an unaccomplished challenge, presumably because of the complexity of target recognition. Here we report detailed analyses of target recognition by Type ISP restriction-modification enzymes. We determined the structure of the Type ISP enzyme LlaGI bound to its target and compared it with the previously reported structure of a...

Sequence determination of restriction-endonuclease recognition sites.

the enzyme DpnII, produced by another strain of D. pneumoniae, recognizes the same sequence, but is inhibited by this same methylated base. The significance of the occurrence of modified nucleotides in eukaryotic DNA is not as yet understood, although a relationship between modification and gene expression has been proposed by several workers (Waalwijk & Flavell, 1978; Bird et al., 1979). By us...

Endonuclease Specificity and Sequence Dependence of Type IIS Restriction Enzymes

Restriction enzymes that recognize specific sequences but cleave unknown sequence outside the recognition site are extensively utilized tools in molecular biology. Despite this, systematic functional categorization of cleavage performance has largely been lacking. We established a simple and automatable model system to assay cleavage distance variation (termed slippage) and the sequence depende...
