| 1 | Protein heterocomplex Heteromer Protein × 2 PDB declaration: dimeric（2） Consistent with protein copy count | Chain A； UniProt 371–603 | Fragment：POLO box domain residues 371-603 | Macrocyclic phosphopeptide 4C × 1 | X-RAY DIFFRACTION X-ray crystallization conditions：VAPOR DIFFUSION；pH 8；291 K；Frozen stocks of protein at 37 mg/mL in 10 mM TRIS pH8, 0.5 M NaCl, 10 mM DTT were thawed and diluted to 10 mg/ml with the same buffer. Complexes with each of three macrocycle compounds (3b, 3c and 4b) were prepared by adding 100 mM stocks of the macrocycle in DMSO directly to the diluted protein to achieve a final concentration of 1 mM. Crystals were grown by hanging drop vapor diffusion, with drops made by mixing equal volumes of protein-macrocycle complex and well solution containing 2-6% PEG-3350. Crystals were cryo-protected by quickly dipping in a solution of 37.5% ethylene glycol in well solution and frozen in liquid nitrogen. | Resolution 1.80 Å R-free 0.239 |

VAPOR DIFFUSION, HANGING DROP；pH 8；291 K；Frozen stocks of protein at 37 mg/mL in 10 mM TRIS pH8, 0.5 M NaCl, 10 mM DTT were thawed and diluted to 10 mg/ml with the same buffer. Complexes with each of three macrocycle compounds (3b, 3c and 4b) were prepared by adding 100 mM stocks of the macrocycle in DMSO directly to the diluted protein to achieve a final concentration of 1 mM. Crystals were grown by hanging drop vapor diffusion, with drops made by mixing equal volumes of protein-macrocycle complex and well solution containing 2-6% PEG-3350. Crystals were cryo-protected by quickly dipping in a solution of 37.5% ethylene glycol in well solution and frozen in liquid nitrogen
