Circularly permuted protein
WebJul 1, 2002 · The ability of the circularly permuted protein to respond to allosteric regulators suggests that the protein is structurally similar to HbAo in these regions distant from the heme cavity. IHP is a potent allosteric regulator which binds with a significantly higher affinity to the same cavity as 2,3 diphosphoglycerate. 34-36 This cavity is ... WebNov 3, 2024 · Circular permutation of fluorescent proteins (FPs) is often the first step in the process of developing single-FP-based GEFPIs. This study explored the tolerance of two far-red FPs, mMaroon1 and mCarmine, towards circular permutation.

WebCircularly permuted fluorescent proteins (FPs) have a growing number of uses in live cell fluorescence biosensing applications. Most notably, they enable the construction of single fluorescent protein-based biosensors for Ca (2+) and other analytes of interest. WebMar 29, 2012 · Circular permutation describes a type of relationship between proteins, whereby the proteins have a changed order of amino acids in their protein sequence, such that the sequence of the first portion of one protein (adjacent to the N-terminus) is related to that of the second portion of the other protein (near its C-terminus ), and vice versa …

The CPM structure of a β-glucanase has been … WebDec 8, 2024 · The circularly permuted construct (CapD-CP) shifts the nucleophilic Thr 352 residue to the N terminus and removes the requirement of internal autoproteolysis, which improves the production of homogeneous protein. In addition, the CapD-CP has greater thermostability than native CapD (CapD-N) ( 29 ).
WebMay 22, 2013 · Indicators for citrate, particularly those applicable to its in vivo detection and quantitation, have attracted much interest in both biochemical studies and industrial applications since citrate is a key metabolic intermediate playing important roles in living cells. We generated novel fluorescence indicators for citrate by fusing the circularly … WebAug 27, 2024 · In circularly permuted FPs (cpFPs), the original N- and C-termini are fused using a peptide linker, while new termini are formed near the chromophore. Such a structure imparts greater mobility to the FP than that of the native variant, allowing greater lability of the spectral characteristics.
