The following might be of interest:

	The Q-linker: a class of interdomain sequences found in
	bacterial multidomain regulatory proteins.
	J.C. Wootton and M.H. Drummond
	Protein Engineering 2(7):535-543 1989

"Q-linkers are...~15-25 residues long and relatively rich in *glutamine*,
arginine, *glutamate*, serine, and *proline*.......
