A 6.8-kilobase DNA fragment containing the sequence coding for the constant region of the mouse immunoglobulin gamma1 heavy chain was cloned from total cellular DNA. Electron microscopic and nucleotide sequencing studies showed that the three protein domains and the hinge region are encoded in separate DNA segments.

ATP induces a conformational change in the Escherichia coli K-12

The process of DNA recognition by the activated form of the restriction endonuclease from E. coli K involves three enzyme-DNA complexes which can be differentiated experimentally. These are: an initial complex formed at a nonspecific site; a recognition complex involving the host specificity site; and a cleavage complex dependent on the presence of ATP.
