Porphyrin Supramolecular Arrays Formed by Weakly Interacting Meso-Functional Groups on Au(111)
The formation of a binary porphyrinic self-assembled system between meso-tetrakis(4-carboxyphenyl) porphyrin (TCPP) and meso-tetrakis(4-dimethyl amino) porphyrin (TDAP) was easily designed through non-covalent interactions in solution and adsorbed on a ...

Heterotropic regulation and negative homotropic cooperativity
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.

The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Synthesis and structure of 3-(14H-dibenzo[a,j]xanthen-14-yl)phenyl nicotinate
In the title compound, C33H21NO3, the dihedral angle between the naphthalene units is 10.85 (4)° and the pyran ring adopts a shallow boat conformation. In the crystal, C—H...N and C—H...O hydrogen bonds link the molecules, enclosing R22(16) ring motifs ...

The two catalytic subunits of typhoid toxin dissociate from the holotoxin in the ER of an intoxicated cell, but only CdtB exits the ER to generate immunosuppressive effects. PltA is retained in the ER and sequestered from its cytosolic target, thus allowing the anti‐inflammatory effects of CdtB to promote intestinal colonization.

Analysis of Interfacial Mechanical Properties and Functional Response Mechanisms of Protein–Polyphenol Composite Systems [PDF]
Protein–polyphenol composite systems have gained attention for their ability to regulate protein structure and functionality. Catechin interacts with oyster water-soluble proteins through non-covalent and covalent pathways, forming composite systems with

A minimal cellulosome‐like system in Cellulosilyticum lentocellum
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.

Metal-Based Drug–DNA Interactions and Analytical Determination Methods
DNA structure has many potential places where endogenous compounds and xenobiotics can bind. Therefore, xenobiotics bind along the sites of the nucleic acid with the aim of changing its structure, its genetic message, and, implicitly, its functions ...
