S. Hagenmaier et al., A NEW PERIPLASMIC PROTEIN OF ESCHERICHIA-COLI WHICH IS SYNTHESIZED INSPHEROPLASTS BUT NOT IN INTACT-CELLS, Journal of bacteriology, 179(6), 1997, pp. 2073-2076
The gene spy from Escherichia coli has been cloned and sequenced. It e
ncodes a precursor of a so far unknown 139-residue, rather basic perip
lasmic protein. It was not detectable immunologically in intact cells
but was produced abundantly in spheroplasts. It could be a stress prot
ein specific for spheroplasting.
