Structural prediction of CS-P450cin fusion protein. (A) Structures of non-fused enzymes of P450cin and CS monomer aligned with the predicted structure of CS-P450cin fusion. (B) Predicted structure of the CS-P450cin fusion protein with a (GSG)3 peptide linker (G3), C-score of I-TASSER = −2.74. P450cin, red cartoon; CS, blue cartoon; (GSG)3 linker, green loop; Heme, pink stick molecule; Residues of active sites, color stick molecules.
