Docking Station Peptide

A docking station peptide is a short, engineered amino acid sequence that provides a defined binding site for recruiting and positioning proteins, biomolecules, or synthetic components. Its function depends on selective molecular recognition, in which the peptide’s sequence and three-dimensional structure promote complementary interactions such as hydrogen bonding, electrostatic attraction, and hydrophobic association. In bioengineering, docking station peptides can organize molecular components on scaffolds, support modular biomaterial design, and improve control over biosensors, drug-delivery systems, and tissue-engineering constructs. Their tunable binding behavior makes them useful for studying biomolecular assembly and developing precise, adaptable interfaces between biological and engineered systems.

Robert M. Rioux, Pennsylvania State University, University Park, PA The Occupational Safety and Health Administration (OSHA) mandates that an emergency eyewash and shower station be easily accessible in all workplaces in which a person could be exposed to injurious and/or corrosive substances. Emergency eyewash and shower stations should be used in the case of a laboratory or workplace accident that involves the spilling of a harmful, possibly corrosive chemical onto the body or the splashing...

We present the synthesis of a split-intein-mediated protein hydrogel. The building blocks of this hydrogel are two protein copolymers each containing a subunit of a trimeric protein that serves as a crosslinker and one half of a split intein. Mixing of the two protein copolymers triggers an intein trans-splicing reaction, yielding a polypeptide unit that self-assembles into a hydrogel. This hydrogel is highly pH- and temperature-stable, compatible with organic solvents, and easily incorporates...
