The AlphaFold Server is a free, web-based platform launched by Google DeepMind and Isomorphic Labs to provide the scientific community with access to AlphaFold 3 . While the original AlphaFold was revolutionary for predicting protein structures, the AlphaFold 3 server expands this capability to virtually all “life’s molecules,” allowing researchers to model how proteins interact with DNA, RNA, ligands, and more in a single, unified system. 🧬 Key Capabilities Unlike its predecessors, the AlphaFold 3 server is a multimodal model. It doesn't just fold proteins; it predicts the joint 3D structure of complex molecular assemblies. Protein-Ligand Interactions: Accurately models how small molecules (drugs) bind to proteins, showing a 50% improvement over traditional docking methods. Nucleic Acids: Predicts the structures of DNA and RNA and how they interact with proteins (e.g., transcription factors or CRISPR complexes). Chemical Modifications: Pr...

This article explains the simple method to compute composition of amino acids in the protein sequence using C++. In this tutorial, I have used Dev C++ v5.11 software for compiling the C++ program. Length of the Protein Sequence Length of the protein sequence is the count ( C ) of the total number of amino acid characters in the protein sequence. Let, Protein Sequence (S) = S 1 S 2 S 3 …S l -1 S l Where, S ∈ {A, C, D, E, F, G, H, I, K, L, M, N, P, Q, R, S, T, V, W, Y} Then, l is the length of the protein sequence (S). Amino Acid Composition of the Protein Sequence Amino acid composition is the sum of count ( C ) of each amino acids in the protein sequence. Count of each amino acids is C A , C C , C D , C E , C F , C G , C H , C I , C K , C L , C M , C N , C P , C Q , C R , C S , C T , C V , C W , and C Y .
