Abstract

The gene spy from Escherichia coli has been cloned and sequenced. It encodes a precursor of a so far unknown 139-residue, rather basic periplasmic protein. It was not detectable immunologically in intact cells but was produced abundantly in spheroplasts. It could be a stress protein specific for spheroplasting.
