Predicting biomolecular structures has become a cornerstone of molecular research, yet the process often feels like navigating a maze without a clear path. Luckily, SAMSON’s integration of AlphaFold-2 offers a powerful, straightforward solution for tackling this challenge efficiently. In this post, we’ll explore how you can use AlphaFold-2 within SAMSON to perform high-quality cloud predictions in just a few steps.
Why Predict Biomolecular Structures?
Understanding the 3D structure of biomolecules such as proteins is crucial for various applications in biomedical research, drug discovery, and molecular biology. However, obtaining these structures experimentally can be time-consuming and expensive. Computational tools like AlphaFold-2 revolutionized the field with their ability to generate accurate predictions, making biomolecular modeling accessible to many researchers.
How AlphaFold-2 is Integrated in SAMSON
SAMSON integrates AlphaFold-2 through the Biomolecular Structure Prediction extension, enabling users to launch structure prediction in a streamlined manner. The process is performed on the cloud for high computational efficiency. Below, we detail the step-by-step workflow for using AlphaFold-2 in SAMSON:
- Navigate to
Home > Predictin the SAMSON interface. - Choose the AlphaFold-2 service.
- Upload one or more FASTA files containing the protein sequences you want to analyze.
- Select the specific AlphaFold model (e.g., monomer or multimer) you wish to use, and define the database for multiple sequence alignment.
- Click Start prediction to launch the process.
Once the prediction is complete, results are accessible directly in SAMSON under the Interface > Cloud jobs menu or on the SAMSON Connect > Account > Jobs page.
Adding Even More Value
The platform does more than just process predictions: it visualizes outputs intuitively. For example, biomolecular structures are colorized based on pLDDT values, which offer insights into model confidence. If you’re working on comparative modeling or drug design, visual cues like this can significantly accelerate the analysis pipeline.
Practical Notes on Usage
It’s important to note that predictions with AlphaFold-2 in SAMSON are carried out using robust machines, including those equipped with high-performance A100 GPUs. The flexibility of the system lets users choose resources based on their needs, balancing speed and cost-effectiveness. You can reach out to SAMSON’s team to request computational credits, or buy credits directly.

Next Steps After Prediction
Once you’ve successfully predicted structures, you can inspect them in SAMSON, evaluate different candidates if necessary, and prepare them for downstream tasks like docking or simulation. If you’re new to these processes, check out the related tutorials provided by SAMSON—such as the Protein Alignment tutorial to compare predicted structures with known ones.
