Amino-Acid-Conjugated Natural Compounds: Aims, Designs and Results

open access: yesMolecules, 2022
Protein is one of the essential macronutrients required by all living things. The breakdown of protein produces monomers known as amino acids. The concept of conjugating natural compounds with amino acids for therapeutic applications emerged from the ...

Partially-PT-symmetric optical potentials with all-real spectra and soliton families in multi-dimensions

open access: yes, 2013
Multi-dimensional complex optical potentials with partial parity-time (PT) symmetry are proposed. The usual PT symmetry requires that the potential is invariant under complex conjugation and simultaneous reflection in all spatial directions.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

The fine implicative structure of European Portuguese conjugation

open access: yesIsogloss, 2021
Recent literature has highlighted the extent to which inflectional paradigms are organised into systems of implications allowing speakers to make full use of the inflection system on the basis of exposure to only a few forms of each word.

The Lactococcus lactis Pan-Plasmidome

open access: yesFrontiers in Microbiology, 2019
Plasmids are autonomous, self-replicating, extrachromosomal genetic elements that are typically not essential for growth of their host. They may encode metabolic capabilities, which promote the maintenance of these genetic elements, and may allow ...

IncHI1 plasmids are epidemic vectors that mediate transmission of tet(X4) in Escherichia coli isolated from China

open access: yesFrontiers in Microbiology, 2023
IntroductionThis study aimed to investigate the genetic factors promoting widespread Q6 dissemination of tet(X4) between Escherichia coli and to characterize the genetic contexts of tet(X4).MethodsWe isolated E.

Conjugation spaces and 4-manifolds

open access: yes, 2010
We show that 4-dimensional conjugation manifolds are all obtained from branched 2-fold coverings of knotted surfaces in Z/2-homology 4-spheres.Comment: 23 pages. (v3) Revisions to the Introduction and section order; references added. (v4) Final version,

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Successful Transfer of a Model T-DNA Plasmid to E. coli Revealed Its Dependence on Recipient RecA and the Preference of VirD2 Relaxase for Eukaryotes Rather Than Bacteria as Recipients

open access: yesFrontiers in Microbiology, 2018
In Agrobacterium-mediated transformation (AMT) of plants, a single-strand (ss) T-DNA covalently linked with a VirD2 protein moves through a bacterial type IV secretion channel called VirB/D4.

GENETIC ASPECTS OF INDIRECT HYPERBILIRUBINAEMIA IN NEWBORNS

open access: yesSlovenska pediatrija, 2022
Indirect hyperbilirubinaemia is a common finding in the neonatal period. There are numerous causes of neonatal indirect hyperbilirubinemia, from excessive bilirubin production, impaired hepatic bilirubin uptake or bilirubin conjugation and increased ...
