Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Aspectos de la relación entre Thalurania Furcata Colombica (Aves Trochilidae) y las flores en que liba, en un bosque subandino Aspectos de la relación entre Thalurania Furcata Colombica (Aves Trochilidae) y las flores en que liba, en un bosque subandino

open access: yesCaldasia, 1986
El mayor nivel de coadaptación ave nectarívora-flor conocido hasta el momento, se ha logrado en los Trochilidae (VAN DER PIJL & DODSON,1969; FEINSINGER et al., 1979) ; tanto, que se ha hablado de flores adaptadas a la polinización por una especie ...

SMA and Spitzer Observations of Bok Glouble CB17: A Candidate First Hydrostatic Core?

open access: yes, 2012
We present high angular resolution SMA and Spitzer observations toward the Bok globule CB17. SMA 1.3mm dust continuum images reveal within CB17 two sources with an angular separation of about 21" (about 5250 AU at a distance of 250 pc).

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These
