We attempted to predict through computer modeling the structure of the light-harvesting complex II (LH-II) of Rhodospirillum molischianum, before the impending publication of the structure of a homologous protein solved by means of X-ray diffraction. The protein studied is an integral membrane protein of 16 independent polypeptides, 8 alpha-apoproteins and(More)
We illustrate in this article how one proceeds to predict the structure of integral membrane proteins using a combined approach in which molecular dynamics simulations and energy minimization are performed based on structural information from conventional structure prediction methods and experimental constraints derived from biochemical and spectroscopical(More)
The use of high stringency selection systems commonly results in a strongly diminished number of stably transfected mammalian cell lines. Here we placed twelve different promoters upstream of an adjacent primary promoter and tested whether this might result in an increased number of colonies; this is in the context of a stringent selection system. We found(More)
We illustrate in this chapter how one proceeds to predict the structure of integral membrane proteins when a highly homologous structure is unknown. We focus here on the prediction of the structure of the light-harvesting complex II (LH–II) of Rhodospirillum molischianum, an integral membrane protein of 16 polypeptides aggregating and binding to 24(More)
Two mutations of the porphobilinogen (PBG) deaminase gene resulting in cross-reacting immunological material (CRIM) positive forms of acute intermittent porphyria (AIP) have been identified by in vitro amplification of cDNA and cloning of the amplified products in a bacterial expression vector. Both mutations resulted from G to A transitions in exon 10 of(More)
