WebApr 13, 2024 · Nevertheless, the fluctuations in the RMSD values of curcumin were not related to the KK or KE forms as the RMSD values of curcumin for SIK3-O_KK-1 and SIK3-O_KE-1 were 1.98 ± 0.31 Å and 1.98 ± 0.25 Å, respectively. Simultaneously, we observed that the KE form of curcumin may cause more fluctuations for curcumin than the KK form. Cyclins were originally named because their concentration varies in a cyclical fashion during the cell cycle.
