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-
متن کاملStructure of 5-hydroxymethylcytosine-specific restriction enzyme, AbaSI, in complex with DNA
AbaSI, a member of the PvuRts1I-family of modification-dependent restriction endonucleases, cleaves deoxyribonucleic acid (DNA) containing 5-hydroxymethylctosine (5hmC) and glucosylated 5hmC (g5hmC), but not DNA containing unmodified cytosine. AbaSI has been used as a tool for mapping the genomic locations of 5hmC, an important epigenetic modification in the DNA of higher organisms. Here we rep...
متن کاملDistribution of hsp65 PCR-restriction enzyme analysis patterns among Mycobacterium avium complex isolates in Thailand.
A total of 227 clinical Mycobacterium avium complex isolates from Thailand were differentiated into species and types by using PCR-restriction enzyme analysis of hsp65. The distribution of types showed the predominance of M. avium I (77%) in blood specimens, whereas M. intracellulare I was more commonly found in pulmonary specimens (44.2%). In addition, infections with M. avium were more likely...
متن کاملHaptoglobin gene subtyping by restriction enzyme analysis.
cell membrane (PS exposure detected by Annexin V binding) events. This is the first time that fetal NRBCs in the maternal circulation have been examined for PS exposure. Our analysis also differs from a recent report made by Kolialexi et al. (13), who reported a high percentage of Annexin V-positive fetal cells in the maternal circulation, which were proposed to be of an apoptotic nature. A maj...
متن کاملDNA cloning without restriction enzyme and ligase.
One common problem in using the traditional DNA cloning procedure is that suitable natural restriction sites are often unavailable for a given task. Creating new restriction sites is often time consuming. Here, I describe a simple technique of producing "customized cohesive ends" by a combination of PCR primer design and lambda exonuclease digestion. These complementary cohesive ends can form h...
