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.

Spirals on octahedral faces of synthetic diamonds
, 1964 Many octahedral faces of synthetic diamonds manufactured by De Beers of Johannesburg have been examined optically. Spirals have been observed for the first time on (111) faces of one crystal. They are of hexagonal shape.

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 ...

Logarithmic spirals and continue triangles
, 2016 In this article we will use some special triangles, to construct polygonal chains that describe the families of logarithmic spirals, among which the celebrated Golden Spiral, Spira solaris and Pheidia ...

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.

Boundary-driven anomalous spirals in oscillatory media
New Journal of Physics, 2017 We study a heretofore ignored class of spiral patterns in oscillatory media as characterized by the complex Landau–Ginzburg model. These spirals emerge from modulating the growth rate as a function of r , thereby turning off the instability at large r ...

FEBS Open Bio, EarlyView.Glioblastoma cells express calcitonin receptor variants (CT receptor isoforms) that may help them survive stress. Using qPCR, transcript‐specific long‐read nanopore sequencing, immunofluorescence co‐localisation and comparative sequence analysis, this study identifies a novel alternatively spliced CALCR transcript that encodes the CTb receptor isoform ...
