Interaction of the restriction endonuclease ScaI with its substrates

|October 11, 1985
Abstract:
The kinetic constants of the site-specific endonuclease, ScaI, for various substrates were determined. We estimated Vmax and Km for octa-, deca-, dodeca-, and hexadecanucleotides and for plasmid pBR322 DNA. Vmax for these substrates were close, but Km were quite different (in decreasing order, octa- greater than deca-, dodeca-, hexadeca- greater than pBR322). The results were discussed with respect to the tertiary structure of substrate.
