Ddt2000 Database |link|

Domains are the "Lego bricks" of evolution. The ddt2000 database has been used extensively to study how domain-domain interactions have emerged, disappeared, or been rewired over evolutionary time. By comparing interaction patterns across species, researchers can infer how multi-domain proteins evolved their current functions.

DDT-1347 Name: Suzuki-Miyaura Cross-Coupling Reactant: Aryl bromide + Aryl boronic acid Product: Biaryl Catalyst: Pd(PPh₃)₄ (5 mol%) Base: Na₂CO₃ Solvent: Toluene/EtOH/H₂O (4:2:1) Temp: 80°C Time: 12 h Yield: 85% Ref: J. Med. Chem. 1999, 42, 1234 Domains are the "Lego bricks" of evolution

Unlike general reaction databases (e.g., Reaxys, SciFinder), DDT2000 is more compact, often used for teaching, quick reference, or legacy system integration in pharmaceutical R&D. : Your file path should look like
