Arg-242 is necessary for allosteric coupling of cyclic AMP-binding sites A and B of RI subunit of cyclic AMP-dependent protein kinase.

The Journal of biological chemistry - 16 Sept 1994

Abstract excerpt

The functional consequences of Arg-242 to Ser or Lys substitutions in type I alpha regulatory (R) subunits of cAMP-dependent protein kinase were analyzed by using recombinant murine R subunits expressed in Escherichia coli. These mutations arose in cAMP-resistant mutants to S49 mouse lymphoma cells and were shown previously to inhibit cAMP binding to site A, the more amino-terminal of two intrachain cAMP-binding...
