A hypothetico-deductive approach to assessing the social function of chemical signalling in a non-territorial solitary carnivore. [PDF]

open access: yesPLoS ONE, 2012
The function of chemical signalling in non-territorial solitary carnivores is still relatively unclear. Studies on territorial solitary and social carnivores have highlighted odour capability and utility, however the social function of chemical ...

Phosphoinositides and inositol phosphates as molecular glues

open access: yesFEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Bias in Random Forest Variable Importance Measures: Illustrations, Sources and a Solution [PDF]

open access: yes, 2006
Variable importance measures for random forests have been receiving increased attention as a means of variable selection in many classification tasks in bioinformatics and related scientific fields, for instance to select a subset of genetic markers ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Chemical segregation of progeny of camphor trees with high camphor c.q. Linalool content

open access: yes, 1998
The propagation of open pollinated seed from two camphor trees with a high camphor and linalool content, respectively, yielded 115 progeny. The chemical composition of the leaf oils of these trees was analyzed by a combination of capillary GC and GC/MS ...

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

GROWTH AND PRODUCTIVITY OF ACID LIME (CITRUS AURANTIFOLIA L.) AS AFFECTED BY SPRAYING GIBBERELLIC ACID [PDF]

open access: yesMinia Journal of Agricultural Research and Development, 2020
In order to study the effect of gibberellic acid concentration and frequencies of application on vegetative growth, leaves mineral content, yield, and fruit physical and chemical properties of acid lime trees (Citrus aurantifolia L), a field experiment ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
