Webb26 feb. 2002 · PhoA has been widely used in topology studies as it folds into an enzymatically active conformation only in the periplasm ( 22, 23 ). In contrast, GFP folds efficiently in the cytoplasm but does not form active enzyme when targeted to the periplasm by a Sec-type signal peptide ( 24 ). Webbencoding a protein of unknown function, which is strongly induced by high environmental acidity (pH < 5.0). We show here that Asr is required for growth at moderate acidity (pH 4.5) as well as for the induction of acid tolerance at moderate acidity, as shown by its ability to survive subsequent transfer to extreme acidity (pH 2.0). lichfield cathedral google maps
