Toward Rational Design of Imprinted Proteins Based on Albumins: Computational and Experimental Studies

Area of Science:

• Biomaterials Science
• Computational Chemistry
• Molecular Recognition

Background:

• Imprinted proteins (IPs) offer potential as artificial recognition systems due to their specificity and sorption capabilities.
• Limited understanding of atomic-level imprinting mechanisms hinders the rational design of more efficient IPs.

Purpose of the Study:

• To describe fundamental principles of protein imprinting at the atomic level using computational modeling.
• To investigate potential molecular associates formed during the imprinting process.

Main Methods:

• Computational modeling of protein-template interactions.
• Experimental validation using bovine serum albumin (BSA) and 4-hydroxycoumarin (4-HC).
• Isothermal titration calorimetry (ITC) and NMR spectroscopy (¹H NMR, DOSY) were employed.

Main Results:

• Modeled potential associates between BSA and 4-HC during imprinting.
• Experimental data corroborated computational findings, evaluating the efficiency of imprinted BSA.
• Provided atomic-level insights into the imprinting process.

Conclusions:

• This research advances the understanding of protein imprinting at a molecular level.
• The findings pave the way for the rational in silico design of novel imprinted proteins.
• Offers a foundation for developing next-generation artificial recognition materials.
