Researchers rapidly determined SARS-CoV protein structures, revealing insights into viral replication and pathogenesis. Many novel protein folds were identified, aiding in understanding the severe acute respiratory syndrome coronavirus.
Area of Science:
- Structural Biology
- Virology
- Bioinformatics
Background:
- The severe acute respiratory syndrome coronavirus (SARS-CoV) outbreak spurred rapid international research efforts.
- A significant number of SARS-CoV protein structures were determined in a short period.
Purpose of the Study:
- To review functional and structural findings of SARS-CoV proteins.
- To highlight structures relevant to viral replication and pathogenesis.
- To discuss the prevalence of novel protein folds in SARS-CoV.
Main Methods:
- Cryoelectron microscopy
- Small-angle X-ray scattering
- Nuclear Magnetic Resonance (NMR) spectroscopy
- X-ray crystallography
- Bioinformatics predictions
Main Results:
- Compilation of diverse structural data for SARS-CoV proteins.
- Identification of structures crucial for understanding viral function and disease.
- Observation of a high proportion of previously unknown protein folds.
Conclusions:
- The rapid structural determination of SARS-CoV proteins has significantly advanced understanding of the virus.
- Structural insights are key to elucidating viral replication mechanisms and pathogenesis.
- The discovery of novel protein folds highlights the unique structural biology of SARS-CoV.

03:01The Replisome
The synthesis of the leading and lagging strands is a highly coordinated process. To explain this, the “Trombone model” was proposed by Bruce Alberts in 1980. The DNA loop formation starts when a primer is synthesized on the parent lagging strand. The loop grows with...
