Complementation and Reconstitution of Fluorescence from Circularly Permuted and Truncated Green Fluorescent Protein [PDF]
Biochemistry, 2009 Green fluorescent protein (GFP) has been used as a proof of concept for a novel "leave-one-out" biosensor design in which a protein that has a segment omitted from the middle of the sequence by circular permutation and truncation binds the missing peptide and reconstitutes its function.

Novel Medical Image Encryption Scheme Based on Chaos and DNA Encoding
IEEE Access, 2019 In this paper, we propose a new chaos-based encryption scheme for medical images. It is based on a combination of chaos and DNA computing under the scenario of two encryption rounds, preceded by a key generation layer, and follows the permutation ...

Testing the role of chain connectivity on the stability and structure of dihydrofolate reductase fromE. coli: Fragment complementation and circular permutation reveal stable, alternatively folded forms [PDF]
Protein Science, 2001 AbstractThe effects of chain cleavage and circular permutation on the structure, stability, and activity of dihydrofolate reductase (DHFR) fromEscherichia coliwere investigated by various spectroscopic and biochemical methods. Cleavage of the backbone after position 86 resulted in two fragments, {1–86} and {87–159}, each of which are poorly structured ...

The Existence of Quasi Regular and Bi-Regular Self-Complementary 3-Uniform Hypergraphs
Discussiones Mathematicae Graph Theory, 2016 A k-uniform hypergraph H = (V ;E) is called self-complementary if there is a permutation σ : V → V , called a complementing permutation, such that for every k-subset e of V , e ∈ E if and only if σ(e) ∉ E. In other words, H is isomorphic with H′ = (V ; V(

Almost Self-Complementary 3-Uniform Hypergraphs
Discussiones Mathematicae Graph Theory, 2017 It is known that self-complementary 3-uniform hypergraphs on n vertices exist if and only if n is congruent to 0, 1 or 2 modulo 4. In this paper we define an almost self-complementary 3-uniform hypergraph on n vertices and prove that it exists if and ...

A note on self-complementary hypergraphs [PDF]
Opuscula Mathematica, 2005 In the paper we describe all self-complementary hypergraphs. It turns out that such hypergraphs exist if and only if the number of vertices of the hypergraph is of the form \(n=2^k\). This answers a conjecture posed by A.

A note on self-complementary 4-uniform hypergraphs [PDF]
Opuscula Mathematica, 2005 We prove that a permutation \(\theta\) is complementing permutation for a \(4\)-uniform hypergraph if and only if one of the following cases is satisfied: (i) the length of every cycle of \(\theta\) is a multiple of \(8\), (ii) \(\theta\) has \(1\), \(2\)

On permutably complemented subalgebras of finite dimensional Lie algebras [PDF]
Algebraic structures and their applications, 2018 Summary: Let \(L\) be a finite-dimensional Lie algebra. We say a subalgebra \(H\) of \(L\) is permutably complemented in \(L\) if there is a subalgebra \(K\) of \(L\) such that \(L=H+K\) and \(H\cap K=0\). Also, if every subalgebra of \(L\) is permutably complemented in \(L\), then \(L\) is called completely factorisable.
