   7.6.2.9 | anionic lipids |
absence of phosphatidylglycerol and/or phosphatidylserine results in trapping of the protein in an inactive state |
655328 |
| 7.6.2.9 | dioleoyl-phosphatidylglycerol |
needed for full osmoregulatory activity |
674658 |
| 7.6.2.9 | glycerol |
at 270 mM, the amount of glycine betaine taken up after 30 seconds is 30% higher than that of the iso-osmotic control sample |
655328 |
| 7.6.2.9 | more |
nucleotide-binding protein domain not stimulated by glycine betaine |
675495 |
| 7.6.2.9 | more |
sucrose and D-fructose have no effects on OpuA activity |
655328 |
| 7.6.2.9 | more |
sucrose and sorbitol show no effect |
671475 |
| 7.6.2.9 | more |
the binding of glycine betaine to purified OpuA and OpuAC does not show any salt dependence or cooperative effects, in contrast to the transport activity |
