Q: What is REDUCE used for?

A: REDUCE is used to add hydrogen atoms to PDB-format molecular structure files. This process is essential for preparing accurate models of proteins for computational simulations, visualization, and structural analysis.

Q: Who created REDUCE?

A: REDUCE was created by Anthony C. Hearn, an Australian-American physicist and computer scientist known for his work in symbolic computation and molecular modeling.

Q: Where can I find documentation or the original paper for REDUCE?

A: REDUCE was first introduced in the 1989 publication titled *“Asparagine and glutamine: using hydrogen atom contacts in the choice of side-chain amide orientation.”* Documentation may also be found through bioinformatics resources or software repositories associated with structural biology tools.
