ATP-binding proteins are members of a protein that is one of the largest, and most ancient proteins present in all extant phyla from prokaryotes to humans. These are transmembrane proteins that function in the transport of a wide variety of substrates across extra- and intracellular membranes, including metabolic products, lipids and sterols, and drugs

ATPint:is a web based tool for prediction of ATP binding residue in protein sequence.It takes amino acid sequence in FASTA format as input and predict the ATP-interacting residues with Support Vector Machine (SVM). These method have been trained and tested using five-fold cross-validation. Residue-wise detail prediction by ATPint is given in tabular format. This table contain three columns (i) amino acid residue, (ii) SVM score and (iii) prediction class.
