Importance of the region around lysine 196 for catalytic activity of adenylyl cyclase from Escherichia coli.

Abstract excerpt

Escherichia coli adenylyl cyclase contains no sequence that corresponds to the previously defined ATP/GTP binding consensus (A,G)XXXXGK(S,T). Using a search for lysine residues located adjacent to glycine residues, three regions that were possible candidates for part of the ATP binding site were identified. These were the residues located at positions 59, 90, and 196. A plasmid vector capable of overexpressing...
