... major interaction site for the adenine moiety. In b1, an arginine residue (Ile417 in rPDE2) binds to N1 and a threonine (Ser419 in rPDE2) inter- acts with N7 and the N 6 amino group. The inter- actions ... cGMP binding [13], and, in PDE6, both of the amino acids corresponding to Phe433 ⁄ Asp434 in rPDE2A are required for cGMP binding [14]. Our initial mutations in cyaB1 GAF B also...
