High-resolution structures reveal protein-RNA recognition themes. Early work on glutamine aminoacyl tRNA synthetase and ATP provided foundational insights into these complex interactions.

Area of Science:

Structural Biology
Molecular Biology
Biochemistry

Background:

The first high-resolution structure of a protein-RNA complex, glutamine aminoacyl tRNA synthetase with tRNA(Gln) and ATP, was determined in 1989.
Since then, structures of RNA complexes with other proteins like elongation factor Tu and viral proteins have been elucidated.

Purpose of the Study:

To review the emerging themes in protein-RNA recognition based on available high-resolution structural data.
To understand the general principles governing how proteins interact with RNA molecules.

Main Methods:

X-ray crystallography was the primary method for determining the reported high-resolution structures.
Comparative analysis of existing protein-RNA complex structures.

Main Results:

Despite a limited number of structures, common principles of protein-RNA recognition are becoming apparent.
These themes likely involve specific molecular interactions and binding mechanisms.

Conclusions:

High-resolution structural studies are crucial for deciphering protein-RNA interactions.
Emerging themes provide a framework for understanding diverse protein-RNA recognition events in biological systems.
