Prolin isomerase
WebThere is evidence that a peptidyl proline isomerase that is specific for -Ser-P-Pro- sequences (P indicates a phosphoryl group) in proteins has something to do with transcription termination. How might this enzyme act on the CTD to affect transcription termination? Expert Answer 1st step All steps Final answer Step 1/3 WebJan 8, 2014 · The activity of the peptidyl-prolyl isomerase was affected when the relevant amino acids were mutated.

WebJun 7, 2024 · We demonstrate that proline/arginine repeat polymers inhibit the folding catalyst activity of PPIA, an abundant molecular chaperone and prolyl isomerase in the brain that is altered in amyotrophic lateral sclerosis. NMR spectroscopy reveals that proline/arginine repeat polymers bind to the active site of PPIA. WebOct 31, 2024 · Background: Regulation of cell death plays a key role in numerous diseases. As a proline isomerase, prolyl cis-trans isomerase NIMA-interacting 1 (Pin1) is important for the regulation of signaling pathways. An in-depth understanding of how Pin1 participates in the process of cell death, which affects the occurrence and development of diseases, will …

These findings provide... WebJul 22, 2013 · Surprisingly, deletion of the proline isomerase domain via the ochre nonsense mutation, K302oc, and many other mutations including deletion of residues 294 to 411 did not compromise GLC7 suppression. Therefore, Fpr3 suppresses Glc7 by using a function other than its proline isomerase activity.
WebReversible proline-directed phosphorylation at Ser/Thr-Pro motifs has an essential role in myogenesis, a multistep process strictly regulated by several signaling pathways that impinge on two families of myogenic effectors, the basic helix-loop-helix myogenic transcription factors and the MEF2 (myocyte enhancer factor 2) proteins.
