Production of endonucleolytic double-strand DNA breaks requires separate strand cleavage events. Although catalytic mechanisms for simple, dimeric endonucleases are known, there are many complex nuclease machines that are poorly understood. Here we studied the single polypeptide Type ISP restriction-modification (RM) enzymes, which cleave random DNA between distant target sites when two enzymes...
The pharmacological actions of morphine and morphine-like drugs such as heroin are mediated primarily through the mu opioid receptor. Previously a single strand DNA element of the mouse mu opioid receptor gene (Oprm1) proximal promoter was found to be important for regulating Oprm1 in neuronal cells. To identify proteins binding to the single strand DNA element as potential regulators for Oprm1...
Measurement of steady-state rates of unwinding of double-stranded oligonucleotides by helicases is hampered due to rapid reannealing of the single-stranded DNA products. Including an oligonucleotide in the reaction mixture which can hybridize with one of the single strands can prevent reannealing. However, helicases bind to single-stranded DNA, therefore the additional oligonucleotide can seque...
