Type I Restriction and Modification Systems

Collaborations

This Web Page briefly details ALL collaborations I have been involved in over the last twenty years!

The list is alphabetical:

Dr Tatyana Akimkina - Russian Academy of Sciences.Tanja at her poster in Brest
This work was initiated after successfully receiving a Wellcome Trust Collaborative Research Grant together with Dr James McClellan (also at Portsmouth). Since then we have produced a number of gDNA libraries from thermophilic bacteria or archaebacteria and we have started a screen for interesting genes including those encoding various topoisomerases and DNA helicases. We also isolated a highly conserved plasmid from Thermotoga maritima that appears to behave as a selfish piece of DNA.

Dr Paul Berryman - Hampshire Scientific Services
This project was an external consultancy to investigate the most reliable method for PCR screening of GM-content in food. The project developed into the use of real-time PCR for the same purpose and showed that the technology could be used to quantify GM-content in various food; although, it also showed there are major problems associated with extraction of high-quality DNA from some foods.

Prof Cees Dekker (Dr David Bensimon, Dr John Gallop, Dr Marie Weiserova and Prof Roberto Favilla) - part of the EC-funded Mol Switch Project investigating the use of EcoR124I and other molecular motors as nanoactuators.  This led to a further EC-funded Project (BioNano-Switch - NEST Pathfinder, Synthetic Biology Grant No. 043288), which has brought two new collaborators to the Consortium - Prof Paulo Freitis, Portugal and Dr Ivo Utke, Switzerland.  Finally David Bensimon and Paulo Freitis have joined with Dr Ralf Seidel (TUDelft) on a new Project funded through the NanoSci-E+ scheme called Molecular Machines.

Dr David Dryden - Edinburgh Dave Dryden and others at Igls 1997University.
David Dryden was at Newcastle University at the same time I was and we spent many hours discussing Type I R-M systems (I did most of the discussing I seem to remember). Amazingly, Dave now heads a group working on the EcoKI R-M system at Edinburgh University, Department of Chemistry. We still discuss our work and have published papers together - many thanks for all of the PhD examinations you have done for me.

Dr Kevin Dybvig - University of Alabama, USA.
This collaboration involves an unusual R-M system from Mycoplasma pulmonis. We are still trying to identify the DNA recognition sequence of this system, but the project has been very problematic!

 

Dr Pavel Janscak and Dr Mark SzczelkunDr Mark Szczelkun - Bristol University.
This collaboration sprang from a discussion about the use of catenanes to determine if the restriction enzyme binds DNA in cis prior to DNA translocation. We have published a number of papers together (initially with Dr Pavel Janscak - second from the right on the above photograph) and the collaboration continues as we work toward understanding EcoR124I as a molecular motor. Pavel has now moved from the Czech group to work with Prof. Tom Bickle at the Biozentrum in Basel.

Prof Gabi Kaufmann - Tel Aviv University, Israel.
Gabi and some of his research workersMy collaboration with Gabi started as a virtual project through email contacts and exchange of information. After a couple of years Gabi and I were lucky enough to obtain one the British Council sponsored UK-Israel Technology Initiative grants (only about 30 were supported in biological science). This led to a three year collaborative project studying the anti-restriction polypeptide Stp,the type IC R-M system EcoprrI and the PrrC anti-codon nuclease.

Dr Marie Weiserova - Czech Academy of Sciences. Pavel, Kathy (my wife), Marie and Josef in Prague
This collaboration started in 1991 through contacts made with Dr Josef Hubacek (on the right of the photograph) and has continued since, but with the Czech research group being led by Dr. Marie Weiserova (in the yellow shirt in the photograph). We have published a number of paper since then and we have both obtained a number of research grants based around this collaborative work.  Dr Weiserova is also part of the EC-funded Mol Switch Consortium.

Dr Marcus Yeo - works for a local SME (Small to Medium-sized Enterprise), Cybersense, with whom we are working toward the use of the multisubunit EcoR124I as a toxin-sensitive biosensor.Cameron Alexander

Darek GoreckiProf. Darek Gorecki and Dr Cameron Alexander - University of Portsmouth.
This collaboration involved a highly imaginative project, funded through a Wellcome Trust Showcase Award, to develop the EcoR124I molecular motor as a controllable dynamic system for gene delivery in a gene therapy system.  The work involved linking "intelligent" polymers to the HsdR subunit of EcoR124I and showing control of activity of the enzyme through collapse of the polymer.

 

Dr Gerry Ronan - Farfield Scientific Limited.
The identification of EcoR124I as a molecular motor has initiated a move toward commercialisation of this research.  Part of this process is a collaboration with Farfield Scientific Limited, with whom we hope to produce an orthogonal biosensing system incorporating the nanoactuator onto the Dual Polarisation Interferometer (DPI).
