A mutation in the putative Mg(2+)-binding site of Gs alpha prevents its activation by receptors.

The properties of a Gs alpha mutant with an Asn substituted for Ser at position 54, designated mutant 54Asn alpha s, were studied after expression in S49 alpha s-deficient (cyc-) cells. Ser-54 in alpha s is comparable to Ser-17 in Ras, which is involved in binding Mg2+ associated with bound nucleoti...
