Each monomer has molecular weight of about 7.500 Da and it consists of 63 amino acids that form two α-helices connected by <scene name='Rop_protein/Wt_rop_loop/2'> a loop </scene>of four amino acids (L29, D30, A31, D32). The two monomers are related with a 2-fold symmetry axis. | Each monomer has molecular weight of about 7.500 Da and it consists of 63 amino acids that form two α-helices connected by <scene name='Rop_protein/Wt_rop_loop/2'> a loop </scene>of four amino acids (L29, D30, A31, D32).
