To maintain genome integrity and avoid tumorigenesis, cells choreograph...
متن کاملIsomerization of Silylallene
The isomerization of silylallene to seven of its isomers has been studied using ab initio molecular orbital theory. The energetics were obtained using quadratically convergent configuration interaction (QCISD(T)) with the 6-311G(d,p) basis set, at geometries optimized by second-order perturbation theory (MP2) with the 6-31G(d) basis set. Test calculations using multiconfiguration wave functions...
متن کاملCross-Talk of Phosphorylation and Prolyl Isomerization of the C-terminal Domain of RNA Polymerase II
Post-translational modifications of the heptad repeat sequences in the C-terminal domain (CTD) of RNA polymerase II (Pol II) are well recognized for their roles in coordinating transcription with other nuclear processes that impinge upon transcription by the Pol II machinery; and this is primarily achieved through CTD interactions with the various nuclear factors. The identification of novel mo...
متن کاملRequirement of carotene isomerization for the assembly of photosystem II in Synechocystis sp. PCC 6803.
Carotene isomerase mutant (crtH mutant) cells of Synechocystis sp. PCC 6803 can accumulate beta-carotene under light conditions. However, the mutant cells grown under a light-activated heterotrophic growth condition contained detectable levels of neither beta-carotene nor D1 protein of the photosystem (PS) II reaction center, and no oxygen-evolving activity of PSII was detected. beta-Carotene a...
متن کاملSerine phosphorylation and proline isomerization in RNAP II CTD control recruitment of Nrd1.
Recruitment of appropriate RNA processing factors to the site of transcription is controlled by post-translational modifications of the C-terminal domain (CTD) of RNA polymerase II (RNAP II). Here, we report the solution structure of the Ser5 phosphorylated (pSer5) CTD bound to Nrd1. The structure reveals a direct recognition of pSer5 by Nrd1 that requires the cis conformation of the upstream p...
