Selectins

Selectins

Cell adhesion is an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain, which...

Synthetic Biology

Synthetic Biology

Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

Area of Science:

Supramolecular chemistry
Carbohydrate recognition

Background:

Natural carbohydrate recognition systems, like lectins, are crucial in biological processes.
Wheat germ agglutinin (WGA) is a well-studied lectin known for binding N-acetyl-D-glucosamine derivatives.

Discussion:

Supramolecular systems in aqueous environments can achieve high affinity and selectivity in molecular recognition.
Synthetic receptors offer tunable properties for specific biological targets.

Key Insights:

A novel synthetic carbohydrate receptor exhibits binding affinity for N-acetyl-D-glucosamine derivatives comparable to the natural lectin WGA.
This synthetic receptor demonstrates enhanced selectivity over WGA for these derivatives.
The findings suggest supramolecular systems can effectively mimic and surpass natural carbohydrate-binding proteins in water.

Outlook:

Further development of synthetic receptors could lead to new diagnostic and therapeutic tools.
This research opens avenues for designing artificial systems with biological recognition capabilities.
