Insertion of the FeB cofactor in cNORs lacking metal inserting chaperones
FEBS Letters, EarlyView.Nitric oxide reductase is an enzyme found in the bacterial denitrification pathway. The NOR active site contains a non‐heme iron, often, but not always inserted with the assistance of chaperones. Here, we study the insertion of FeB in the subfamily of cNORs lacking chaperones and found a putative channel, conserved in the family, perhaps enabling the ...

Taurine promotes glucagon‐like peptide‐1 secretion in enteroendocrine L cells
FEBS Letters, EarlyView.Taurine, a sulfur‐containing amino acid, is likely taken up by enteroendocrine L cells via the taurine transporter. This process increases the levels of cytosolic ATP. The increase in intracellular Ca2+ concentrations and glucagon‐like peptide‐1 secretion through membrane depolarization is caused by the closure of ATP‐sensitive potassium channels ...

Sheaves of nonlinear generalized function spaces [PDF]
arXiv, 2017 We provide a framework for the construction of diffeomorphism invariant sheaves of nonlinear generalized functions spaces. As an application, global algebras of generalized functions for distributions on manifolds and diffeomorphism invariant algebras of generalized functions for ultradistributions are constructed.

FEBS Letters, EarlyView.The NlpC_P60 superfamily of peptidases is recognised by its key role in bacterial cell wall homeostasis. Recently, studies have also described the involvement of NlpC_P60‐like enzymes in bacterial competitive mechanisms and pathogenesis across several lineages.

Una proprietà di una classe di trasformazioni integrali che generalizza la trasformata di Fourier [PDF]
Rendiconti di Matematica e delle Sue Applicazioni, 1994 : In this paper we first recall of a known property of the Fourier transform (Proposition I), connected with Hermite polynomials, and then we extend this property to a general class of Integral Transform related with different orthogonal polynomial sets.

Generating functions of wormholes [PDF]
Modern Physics Letters A, 2019 It is known that wormhole geometry could be found solving the Einstein field equations by tolerating the violation of null energy condition (NEC). Violation of NEC is not possible for the physical matter distributions, however, it can be achieved by considering distributions of “exotic matter”.

Making tau amyloid models in vitro: a crucial and underestimated challenge
FEBS Letters, EarlyView.This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Determinantal generating functions of colored spanning forests
International Journal of Mathematics and Mathematical Sciences, 2004 The color type of a spanning forest of a graph with colored edges is defined and, subsequently, it is proved that the generating function of such spanning forests is obtained as the formal expansion of a certain determinant.

The method for obtaining expressions for coefficients of reverse generating functions [PDF]
arXiv, 2012 The powers of generating functions and its properties are analyzed. A new class of functions is introduced, based on the application of compositions of an integer $n$, called composita. The methods for obtaining reciprocal and reverse generating functions, and solutions of the functional equations $F(A(x))=G(x)$, where $A(x)$ is an unknown generating ...
