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...
متن کاملSequence-specific endonuclease BamHI: relaxation of sequence recognition.
The effect of glycerol on the specificity of DNA cleavage by the restriction endonuclease BamHI has been examined. In addition to the canonical G decreases from G-A-T-C-C site, BamHI cuts DNA at several sites that we have named noncanonical BamHI.1 sites. The number of BamHI.1 sites in simian virus 40 and pBR322 was determined to be 13 for each DNA. Cutting sites determined by DNA sequence anal...
متن کاملCrystal structure of restriction endonuclease BglI bound to its interrupted DNA recognition sequence.
The crystal structure of the type II restriction endonuclease BglI bound to DNA containing its specific recognition sequence has been determined at 2.2 A resolution. This is the first structure of a restriction endonuclease that recognizes and cleaves an interrupted DNA sequence, producing 3' overhanging ends. BglI is a homodimer that binds its specific DNA sequence with the minor groove facing...
متن کاملAsymmetric photocross-linking pattern of restriction endonuclease EcoRII to the DNA recognition sequence.
The EcoRII homodimer engages two of its recognition sequences (5'-CCWGG) simultaneously and is therefore a type IIE restriction endonuclease. To identify the amino acids of EcoRII that interact specifically with the recognition sequence, we photocross-linked EcoRII with oligonucleotide substrates that contained only one recognition sequence for EcoRII. In this recognition sequence, we substitut...
متن کاملKpnI restriction endonuclease and methyltransferase exhibit contrasting mode of sequence recognition.
The molecular basis of the interaction of KpnI restriction endonuclease (REase) and the corresponding methyltransferase (MTase) at their cognate recognition sequence is investigated using a range of footprinting techniques. DNase I protection analysis with the REase reveals the protection of a 14-18 bp region encompassing the hexanucleotide recognition sequence. The MTase, in contrast, protects...
