Circular permutation and receptor insertion within green fluorescent proteins.
Many areas of biology and biotechnology have been revolutionized by the ability to label proteins genetically by fusion to the Aequorea green fluorescent protein (GFP). In previous fusions, the GFP has been treated as an indivisible entity, usually appended to the amino or carboxyl terminus of the host protein, occasionally inserted within the host sequence. The tightly interwoven, three-dimens...
متن کاملCircular Permutation of Red Fluorescent Proteins
Circular permutation of fluorescent proteins provides a substrate for the design of molecular sensors. Here we describe a systematic exploration of permutation sites for mCherry and mKate using a tandem fusion template approach. Circular permutants retaining more than 60% (mCherry) and 90% (mKate) brightness of the parent molecules are reported, as well as a quantitative evaluation of the fluor...
متن کاملCircular Permutation in Proteins
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 (see Figure 1). This is directly analogous to the mat...
متن کاملImproved Green-emitting Fluorescent Proteins
The advent of fluorescent proteins (FPs) has redefined the use of fluorescence microscopy in every biological discipline. Green fluorescent protein (GFP) and its variants are commonly used in celluar imaging studies. Recently, a novel fluorescent protein, named vivid Verde Fluorescent Protein (VFP), was isolated from Cyphastrea microphthalma, a scleractinian coral found in the warmer waters of ...
