Solutions of $D_{\alpha}$ = 0 from Homogeneous Invariant Functions
, 2000 We prove that the existence of a homogeneous invariant of degree n for arepresentation of a semi-simple Lie group guarantees the existence ofnon-trivial solutions of D_{\alpha} = 0: these correspond to the maximum valueof the square of the invariant ...

Invariant solutions of generalized Fisher-KPP equation
, 2019 In this paper, we consider a hyperbolic generalized Fisher-KPP equation: $\varepsilon^2 u_{tt} + g(u) u_t = ( k(u) u_x )_x +f(u)$ where $f$, $g $ and $k$ are arbitrary smooth functions of variable $u$ and $\varepsilon$ is a speed parameter.

FEBS Open Bio, EarlyView.KDAC6 has been associated with cell motility and actin structures, but specific domain contributions are not established. The two catalytic domains have differential effects on motility and F‐actin regulation, affecting cortical F‐actin density, motility, stress fibers, and cell spreading.

FEBS Open Bio, EarlyView.We report the first β‐glucosidase with demonstrated hydrolytic activity on an N‐linked glycopyranoside. The enzyme, native to maize, was biochemically characterised for this novel reaction, and structural modelling of the enzyme–substrate complex revealed several clues to the underlying reduced catalytic rate relative to its native O‐glycopyranoside ...

FEBS Open Bio, EarlyView.Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

Constant invariant solutions of the Poincare center-focus problem
Electronic Journal of Differential Equations, 2010 We consider the classical Poincare problem $$ frac{dx}{dt}=-y-p(x,y),quad frac{dy}{dt}=x+q(x,y) $$ where $p,q$ are homogeneous polynomials of degree $n geq 2$.

Adenosine triphosphate as a modulator of protein interactions and stability
FEBS Open Bio, EarlyView.ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...

Multiple symmetric solutions for a singular semilinear elliptic problem with critical exponent
Electronic Journal of Differential Equations, 2012 Let be $Gamma$ a closed subgroup of $O(N)$. We consider the semilinear elliptic problem $$displaylines{ -Delta u-frac{b(x)}{| x|^2}u-a(x)u=f(x)| u|^{2^{ast }-2}uquad hbox{in }Omega ,cr u=0 quadhbox{on } partial Omega , }$$ where $Omega subset ...

FEBS Open Bio, EarlyView.We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

Heterotropic regulation and negative homotropic cooperativity
FEBS Open Bio, EarlyView.We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.
