A good place to start would be to look at a book by Mark Ptashne, called
'A genetic switch' published by Blackwell Scientific Press (I don't have
it in front of me but I think I'm correct). A new edition came out last
year. Mark Ptashne has done a lot of work on the lambda repressor so 
looking at some of his papers would also be a good idea (especially the ones
published in Cell.
