Abstract

In structure-function studies on bovine rhodopsin by in vitro site-specific mutagenesis, we have prepared three mutants in the cytoplasmic loop between the putative transmembrane helices E and F. In each mutant, charged amino acid residues were replaced by neutral residues: mutant 1, Glu239----Gln; mutant 2, Lys248----Leu; and mutant 3, Glu247----Gln, Lys248----Leu, and Glu249----Gln. The mutant rhodopsin genes were expressed in monkey kidney (COS-1) cells. After the addition of 11-cis-retinal to the cells, the rhodopsin mutants were purified by immunoaffinity adsorption. Each mutant gave a wild-type rhodopsin visible absorption spectrum. The mutants were assayed for their ability to stimulate the GTPase activity of transducin in a light-dependent manner. While mutants 1 and 3 showed wild-type activity, mutant 2 (Lys248----Leu) was inactive.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
