Illicit Transport: The Oligopeptide Permease [PDF]
Proceedings of the National Academy of Sciences, 1973 The oligopeptide permease of Escherichia coli has been characterized by Payne, Gilvarg, and their colleagues. We have confirmed its existence in Salmonella typhimurium , and have isolated a series of mutants lacking the permease.

Predicting the Regioselectivity of Mechanochemical Bond Scission in Complex Molecules
Transformative Chemistry, EarlyView.Covalent‐bond peak force network (CBPFNet), a physics‐informed graph attention framework, predicts mechanochemical bond scission regioselectivity directly from equilibrium structures with DFT‐level accuracy. By uncovering the ‘stiffness mismatch’ mechanism, this work enables the rational design of programmable mechanical fuses for next‐generation ...

Iflaviruses in arthropods: when small is mighty
Insect Science, EarlyView.Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

An update on the landscape of collagen bioactive fragments
The FEBS Journal, EarlyView.The remodeling of the extracellular matrix releases collagen bioactive fragments, which exert molecular functions and regulate numerous biological processes via several signaling pathways. Here, we summarize the latest findings describing the roles of major bioactive fragments from collagens I, IV, VI, and XVIII in various physiological and ...

The synthesis and characterization of polypeptide-adriamycin conjugates and its complexes with adriamycin. Part I [PDF]
, 1985 Poly(α-l-glutamic acid) (PGA) was grafted with amino acid and oligopeptide spacers up to 5 amino acids with the use of N,N'-carbonyldiimidazole and 2,3-dihydro-1,2-benz-isothiazole-3-on-1, 1-dioxide (saccharin) as an additive, and these polypeptides were

Bio‐active designed peptide for hair keratin strengthening
International Journal of Cosmetic Science, EarlyView.Bioactive tripeptides through in silico screening revealed KCV (Tripeptide‐132) as the most promising keratin‐targeting candidate. Experimental studies confirmed its superior hair‐strengthening performance with 44% tensile strength enhancement, 50% breakage reduction, improved surface integrity and fibre penetration.

Degradation of connective tissue matrices by macrophages. III. Morphological and biochemical studies on extracellular, pericellular, and intracellular events in matrix proteolysis by macrophages in culture. [PDF]
, 1980 We have shown that macrophages in culture degrade the glycoproteins and amorphous elastin of insoluble extracellular matrices. Ultrastructural observation of the macrophage-matrix interaction revealed that connective tissue macromolecules were ...
