For molecular modelers, accurately predicting biomolecular structures is a critical step in designing and understanding molecular systems. However, many find it challenging to access powerful prediction tools due to complex workflows or high computational costs. SAMSON, the integrative molecular design platform, provides a user-friendly solution with its AlphaFold-2 capabilities, making accurate biomolecular structure prediction both accessible and efficient.
Why AlphaFold-2 and SAMSON?
AlphaFold-2 is a breakthrough deep learning model that predicts protein structures with remarkable accuracy. Coupling this tool with SAMSON’s intuitive interface allows molecular scientists to focus on their design goals without worrying about complicated setups or infrastructure. Whether you’re dealing with monomers or multimers, SAMSON’s cloud-based prediction capabilities powered by AlphaFold-2 streamline the process.
Step-by-Step Guide to Prediction
Getting started with AlphaFold-2 in SAMSON is straightforward. Here’s how you can do it:
- Navigate to
Home > Predictwithin the SAMSON interface. - Select the AlphaFold-2 service from the menu.
- Upload one or more
FASTAfiles containing your sequences. - Choose the prediction model (e.g., monomer or multimer) and the database for multiple sequence alignment to suit your needs.
- Click Start prediction, and the magic begins on the cloud.
Enhanced Visualization
Once the prediction is complete, SAMSON presents the results in a visually informative manner. Structures are often colorized based on pLDDT values, offering insights into prediction confidence. You can view the completed job under Interface > Cloud jobs or via your SAMSON Connect Account.
Flexible and Powerful Computational Resources
The predictions leverage high-performance cloud machines equipped with advanced GPUs (e.g., A100) for fast and efficient computation. This scalability ensures that you can handle complex systems while optimizing your time and budget.
