The GTP-dependent restriction enzyme McrBC consists of two polypeptides: one (McrB) that is responsible for GTP binding and hydrolysis as well as DNA binding and another (McrC) that is responsible… (More)
A series of T7-promoter based bicistronic expression vectors was constructed in order to produce the complex of the Anabaena sp. PCC 7120 DNA/RNA non-specific nuclease NucA and its inhibitor NuiA.… (More)
The goal of this research is to improve the programmability of DNA-based computers. Novel clockable microreactors can be connected in various ways to solve combinatorial optimisation problems, such… (More)
Sequence alignment of non-hammerhead viroids (Pospiviroidae) reveals that they can be divided into large and small viroids. Covariation analysis of these groups provides evidence for a rod-like… (More)
The program 'MacStAn' for the Apple Macintosh generates random sequences and can analyze their tendency to form secondary structure or translation products as well as their mono-, di- and… (More)
G + C-rich viroids proper exhibit a unique dinucleotide composition in that AU and UA are much less frequent than expected. Thus, evaluation of the dinucleotide pattern allows a quick discrimination… (More)
