Both this structure and the structure determined in [21] were obtained at acidic pH, suggesting that acidic pH is energetically favorable for NhaA crystallization. Satisfactorily, the two structures are identical aside from loops and the position of TM X (Fig. 3a and b). In the first ...
also found several nicotinic acetylcholine receptor subunits with sexually dimorphic expression. Nicotinic acetylcholine receptors are critical components of the efferent auditory system in vertebrates23. Moreover, a single muscarinic acetylcholine receptor was found, as were several metabotropic and ionotropic ...
The DNA in the published structure is 100% AT, over-twisted and slightly narrower than B-form DNA. In the accompanying experiments, GapR is proposed to associate with positively supercoiled chromosomal DNA5, which is often found ahead of the replication fork and RNA polymerase6. GapR was found...
