The radius of gyration (Rg ) is an important parameter reflecting the spatial compactness of the mRNA tertiary structure, with smaller values indicating tighter structures. This paper constructed a protein dataset containing folding rates for 105 known proteins and calculated the corresponding mRNA tertiary structures using the 3dRNA and 3DNA software. From the computational results, it extracted the radius of gyration values and analyzed the correlation between protein folding rates and the radius of gyration of the mRNA tertiary structure. The results show a highly significant negative correlation between the mRNA tertiary structure Rg and protein folding rates (R=-0.426, P= 6.01×10⁻⁶). By classifying the 105 proteins based on secondary structure and folding type, differences are found in the correlation levels between the mRNA tertiary structure Rg and protein folding rates across various protein categories. This study indicates that the radius of gyration of the mRNA tertiary structure has a significant impact on protein folding rates.
