Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

open access: yesFEBS 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.

In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols

open access: yesFEBS Open Bio, EarlyView.
Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

Adenosine triphosphate as a modulator of protein interactions and stability

open access: yesFEBS 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 ...

Dual native G‐quadruplex folding is associated with chromatin looping at the MYC locus

open access: yesFEBS Open Bio, EarlyView.
BG4‐detectable G‐quadruplex (G4) in HaCaT and NHEK keratinocytes identified folded and unfolded G4s enriched at promoters/TSSs and active enhancers, whereas unfolded G4s also overlapped weak/poised enhancers. At MYC–PVT1, 3C‐qPCR detected enhancer–promoter looping only when G4s were simultaneously folded at both regulatory elements under native ...

Snag density and stand age, but not stand size, explain occupancy and reproduction of an imperiled cavity nester in early successional forest

open access: yesAvian Conservation and Ecology, 2022
Many early successional and disturbance-dependent bird species have declined over the past several decades. Cavity-nesting birds in early successional forests are vulnerable because they often require specific habitat characteristics and frequent ...

Heterotropic regulation and negative homotropic cooperativity

open access: yesFEBS 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.

Seasonal influences on classroom occupancy, fine particulate matter exposure, and indoor air quality in South African schools

open access: yesEnvironmental Research Communications
Indoor air quality (IAQ) in classrooms is influenced by factors such as room geometry, occupancy levels, and seasonal fluctuations. This study explored the relationships among occupancy metrics, exposure to fine particulate matter (PM _2.5 ), and comfort

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

open access: yesFEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Mislabeled and Misunderstood: Large Mammal Distribution Underscores Ecological Significance of Agro‐Pastoral “Wastelands” in India's Deccan Peninsula

open access: yesEcology and Evolution
Multi‐use landscapes are now recognized for their value in supporting biodiversity and aiding species conservation, including charismatic megafauna. However, semi‐arid open‐canopy human‐use landscapes have faced multiple anthropogenic stressors over the ...
