   7.6.2.9 | ATP + H2O |

| 7.6.2.9 | ATP + H2O + dimethylsulfonioacetate/out |
OpuA is a classic ABC importer that relies on a substrate binding protein priming the transporter with specificity and selectivity |
| 7.6.2.9 | ATP + H2O + glycine betaine/out |
- |
| 7.6.2.9 | ATP + H2O + glycine betaine/out |
accumulation of glycine betaine which functions as an osmoprotectant, the glycine betaine transport system is osmotically regulated at the level of gene expression and at the level of transport activity |
| 7.6.2.9 | ATP + H2O + glycine betaine/out |
a transmembrane osmotic gradient, outside hyperosmotic relative to the inside, of both ionic and nonionic compounds is able to osmotically activate OpuA. OpuA can act both as osmosensor and osmoregulator |
| 7.6.2.9 | ATP + H2O + glycine betaine/out |
enzyme is responsible for the cold-activated and osmotically activated glycine betaine transport |
| 7.6.2.9 | ATP + H2O + glycine betaine/out |
enzyme is involved in cytoplasmic accumulation of exogenous betaine which has osmoprotective properties, transcription of busA is strongly regulated by the external osmolarity of the medium |
| 7.6.2.9 | ATP + H2O + glycine betaine/out |
the ability of the food-borne pathogen Listeria monocytogenes to tolerate environments of elevated osmolarity and reduced temperature is due in part to the transport and accumulation of the osmolyte glycine betaine by the glycine betaine transport system |
| 7.6.2.9 | ATP + H2O + glycine betaine/out |
high osmolarity stimulates de novo synthesis of OpuD and activates preeixisting OpuD proteins to achieve maximal glycine betaine uptake activity |
| 7.6.2.9 | ATP + H2O + glycine betaine/out |
expression of the opuA operon is under osmotic control |
