The original DDT2000 is now rarely used in its raw text form. Instead, its data live on in:
: The "database" itself is a massive collection of XML files—often several gigabytes—containing the definitions of every parameter, sensor, and command for thousands of ECU variations. ddt2000 database
The ddt2000 database systematically catalogs these interactions. It extracts data from the PDB, applies a specific set of algorithms to identify domain boundaries, and then records the contact points, interface residues, and energetic contributions of each interaction. This makes it an invaluable tool for understanding protein dynamics, predicting interaction partners, and engineering novel proteins. The original DDT2000 is now rarely used in its raw text form
The latest machine-readable version (as of 2024, often called DDT2020 by users, though the canonical name persists) is hosted at: and then records the contact points
