Molecular modelers often face the challenge of predicting accurate biomolecular structures, an essential step for understanding protein behavior or drug design. Enter AlphaFold-2, a state-of-the-art tool integrated into SAMSON, the integrative molecular design platform. In this blog post, we’ll explore how you can leverage AlphaFold-2 within SAMSON to predict structures reliably and efficiently, even if you’re new to the field.
Why Use AlphaFold-2 in SAMSON?
AlphaFold-2 has revolutionized structural biology by predicting highly accurate protein structures in record time. SAMSON takes AlphaFold-2’s capabilities further by offering an intuitive interface for conducting your predictions seamlessly in the cloud. Whether you’re dealing with a monomer, a multimer, or another protein model, SAMSON helps you effortlessly set up and interpret your jobs.
Step-by-Step Guide to Predicting with AlphaFold-2
Predicting structures with AlphaFold-2 in SAMSON is simple and convenient. Here’s how:
- Open
Home > Predictin SAMSON. - Select the AlphaFold-2 service.
- Upload one or more FASTA files containing your protein sequences.
- Choose the AlphaFold model best suited for your work. Available options include monomer, multimer, etc.
- Pick the database for multiple sequence alignments based on your requirements.
- Click Start prediction and let the secure cloud-powered platform handle the rest.
Accessing Results and Visualizing Confidence Values
Once your prediction is complete, you can easily access results in SAMSON under Interface > Cloud jobs or via your SAMSON Connect account. Moreover, SAMSON provides an incredibly useful feature: coloring predicted structures based on pLDDT values (a confidence score). This helps you visually assess which parts of the structure are more likely to be accurate, guiding your interpretations.
