I am trying to clone a promoter sequence to a Vector. Now I have a question
on designing primers. I want to add a restriction enzyme at the end of each
primer, and I also heard that it is better to add a few bp around the
restriction enzyme for it to be cleaved. Does anyone know where I can find
such information on which nucleotide to be added to different restriction
enzyme?
(I read New England catalog book and did not find such information.)
Thank you!

You leave me no choice but . I can not stand someone without any chemistry
sense when he/she is a biologist.
Chemical reaction is a on/off equilibrium. Some enzymes pick up the first
substance first and then the second one if the space arrangement is allowed
in the active site; some enzymes bind to a coordinated substance complex if
the reaction needs both substances available at the same time to fit into
the active site. It depends on the nature of individual enzymes. Since ssDNA

OK, you want basic chemistry and here is basic chemistry.
“Since ssDNA
can not bind to the editing enzyme alone in vitro, the conclusion will be
the enzyme needs the second substance that is a conformation-ready genomic
DNA to form a functional enzyme-ssDNA-genomic target DNA complex to complete
the reaction. ”
----This is so wrong. There could be 100 reasons why an enzyme does not bind
a substance. For example, temperature, pH. Most importantly, it directly
contradicts Han’s data (Fig 1,2).
