SADA is a structural analogue-based protein structure domain assembly method assisted by deep learning, which includes 5 steps. (1) detects structural analogues of the full-chain from the constructed multi-domain protein structure database (MPDB) according to the input protein domain models; (2) Constructs an initial model based on the detected 1st-ranked analogue; (3) Utilizes a deep learning network to predict the inter-residue distance distribution; (4) Builds multi-domain protein specificity force field for guiding domain assembly based on the predicted residues distance distribution and the property of multi-domain protein; (5) Assembles the domain models to generate final full-chain model by the proposed two-stage differential evolution algorithm from the initial model. (see example for a SADA assembly result of 2-domains protein ).

SADA also provides other 2 functions. (1) Structural analogues detection; (2) Culling the whole MPDB according to input criteria.
