I want to predict the protein 3D structure by using computational tools. In this case, amino acid sequences are available only. What software would be best with maximum accuracy to predict this protein 3D structure?
You can use I-TASSER, which is the best tool for 3D structure generation of a protein. Or, if you want to predict structure so fastly, you can use trRosetta server (https://yanglab.nankai.edu.cn/trRosetta/).
but if your protein does not have a template structure with at least 25% of identity, you need to perform a de novo assembly. In this case, you can use ROBETTA webserver https://robetta.bakerlab.org/
