The groESL operon of the halophilic lactic acid bacterium Tetragenococcus halophila

The groESL operon of the halophilic lactic acid bacterium Tetragenococcus halophila was cloned by a PCR-based method. The molecular masses of GroES and GroEL proteins were calculated to be 10,153 and 56,893 Da, respectively. The amount of groESL mRNA was increased 3.8-fold by heat shock (45degC), an...

Zusammenfassung:The groESL operon of the halophilic lactic acid bacterium Tetragenococcus halophila was cloned by a PCR-based method. The molecular masses of GroES and GroEL proteins were calculated to be 10,153 and 56,893 Da, respectively. The amount of groESL mRNA was increased 3.8-fold by heat shock (45degC), and 4-fold by high NaCl (3-4 M). The Bacillus subtilis s**A-like constitutive promoter existed in front of groES, and was used under both normal and stress (heat shock and high salinity) conditions.
