Hi maintainers, thank you for making the task materials available. While checking the supplied structures, we noticed that the two descriptions in Chemistry_001/task_info.json refer to FKBP12–FK506, whereas the files correspond to the UHRF1 tandem Tudor domain–histone H3 peptide complex in PDB entry 2L3R.

This PR proposes a small correction to those descriptions, including the trimethyllysine-containing H3 peptide and the protein's full-atom coverage. It also links the RCSB source entry so that the molecular identities are easy to verify.

Validation:

• Parsed the updated JSON and checked that both declared data paths exist.
• Counted 2,591 protein ATOM records and 161 CA records. All 161 CA residue identities and coordinates match chain A of the first NMR model in RCSB 2L3R.
• Counted 194 atoms in the SDF, including hydrogens. All 90 non-hydrogen atoms match chain B of that RCSB model by element and coordinates rounded to 0.001 Å.
• Compared the JSON objects: the only changed fields are the two data descriptions.

This addresses the structure-description question in #14. We would appreciate your review, particularly if there is additional preparation provenance that should be reflected in the descriptions. Thank you!
