General Information

EC Number General Information Comment Organism
1.14.13.251 physiological function deletion of the GbcAB betaine catabolism genes reduces osmotolerance at a high osmolarity. At high osmolarity, the mutant lacking GbcAB accumulates high betaine levels and low endogenous solutes and exhibits reduced expression of the solute synthesis genes. The GbcAB mutant and a mutant deficient in the synthesis of the compatible solutes NAGGN and trehalose exhibit similar reductions in osmotolerance and also in fitness on bean leaves. Activation of betaine catabolism at high osmotic stress results, in part, from induction of transcriptional activator GbdR Pseudomonas syringae
