3.1.3.69	physiological function	deletion of the entire coding sequence of response regulator slr1588 compromises the expression of the downstream situated StpA gene, which encodes glucosylglycerol-phosphate phosphatase. Mutation of slr1588 by deleting the N-terminal part of this protein (1slr1588-F976) does not affect StpA expression, glucosylglycerol accumulation as well as salt tolerance, while the mutation of StpA results in the a salt-sensitive phenotype. In the 1slr1588-F976 mutant, SpsA is up-regulated but sucrose content is lowered due to increased invertase activity	750630
