Assessing the vulnerability of marine sedimentary organic carbon : the influence of anthropogenic disturbance [PDF]

open access: yes, 2023
As anthropogenic carbon dioxide (CO₂) concentrations rise, there is an increasing need to re-evaluate our understanding of the complex interactions involved within the global carbon (C) cycle. C stored within marine sediments have previously been largely

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

open access: yesFEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

open access: yesFEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Interstratal dewatering origin for polygonal patterns of sand-filled cracks: a case study from late Proterozoic metasediments of Islay, Scotland [PDF]

open access: yes, 1998
Sand-filled cracks from the Lower Fine-grained Quartzite of Dalradian (late Proterozoic) age on the Island of Islay, western Scotland, may be divided into two main types, both of which form orthogonal and non-orthogonal closed patterns on bedding ...

Exon 7 splicing of ERα predicts poor prognosis and increases phenotypic heterogeneity in luminal a subtype breast cancer

open access: yesFEBS Open Bio, EarlyView.
ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.

Sedimentary environmental evolution of the Xiazijie area (Mahu Sag, Junggar Basin, Northwestern China) during the Early to Middle Triassic

open access: yesFrontiers in Earth Science
Fan-delta sandstones or conglomerates constitute important reservoirs for oil and gas worldwide. The Early to Middle Triassic succession in the Xiazijie area of the Mahu Sag of the Junggar Basin represents a critical hydrocarbon-bearing interval, yet its

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

open access: yesFEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Sedimentological analysis and hydrocarbon potential of the upper devonian-lower carboniferous Tahara sandstones, ghadames basin, western Libya [PDF]

open access: yes, 1998
The Palaeozoic (Upper Devonian-Lower Carboniferous) Tahara Formation, western Libya, was deposited in shallow-water, marginal and nearshore marine environments influenced by waves and storms.
