Peptidyl-prolyl isomerases: a new twist to transcription.

Peptidyl-prolyl isomerases (PPIs) catalyse the cis-trans isomerisation of peptide bonds N-terminal to proline residues in polypeptide chains. They have roles in the folding of newly synthesised proteins and in the function of the immune system. In addition, members of the parvulin-like family of PPIs have been implicated in cell cycle control. Their activity is directed by the prior phosphoryla...

Plant organelles contain distinct peptidylprolyl cis,trans-isomerases.

Peptidylprolyl cis,trans-isomerase (PPIase) activity was detected in the cytosol, mitochondria, and chloroplast of pea plants. Cyclosporin A inhibited the activity largely localized to the mitochondrial matrix while rapamycin inhibited the PPIase activity associated with the mitochondrial membranes. Differential inhibition by the two immunosuppressive drugs, the specific binding of these drugs ...

Simulation of a New Process Design to Fabricate a Rectangular Twist Waveguide Using Extrusion and a Twist Die

The aim of the present study is to determine the feasibility of making a rectangular twist waveguide used to rotate electromagnetic waves. For this purpose, the process of fabricating an aluminum rectangular twist waveguide was simulated by making use of finite element method and Deform software. The optimum length and angle of the twist die for manufacturing a twist waveguide with inner cross ...

Peptidyl-prolyl cis/trans isomerases and transcription: is there a twist in the tail?

Eukaryotic transcription is regulated predominantly by the post-translational modification of the participating components. One such modification is the cis-trans isomerization of peptidyl-prolyl bonds, which results in a conformational change in the protein involved. Enzymes that carry out this reaction include the yeast peptidyl-prolyl cis/trans isomerase Ess1 and its human counterpart Pin1, ...

A Bacterial Protein Puts a New Twist on DNA Transcription

September 2006 | Volume 4 | Issue 9 | e304 One reason to sequence the genomes of non-human organisms is to better understand our similarities and differences. And, at fi rst sight, it is hard to imagine a eukaryote more different from humans than Tetrahymena thermophila. A relative of Paramecium, this single-celled creature has a strong but fl exible exterior covered with rows of cilia; but it ...
