Noncrystallographic symmetry (NCS) | NCS oper: (Code: given Matrix: (-0.993679, -0.001063, 0.112252), Vector: Details | THIS ENZYME IS A MULTI-COMPONENT PROTEIN COMPLEX AND IS A HOMODIMER. EACH MONOMER IS COMPOSED OF 13 DIFFERENT SUBUNITS AND SEVEN METAL CENTERS: HEME A, HEME A3, CUA, CUB, MG, NA, AND ZN. THE SIDE CHAINS OF H 240 AND Y244 OF SUBUNITS A AND N ARE LINKED TOGETHER BY A COVALENT BOND. THE ELECTRON DENSITY OF REGION FROM D(Q)1 TO D(Q)3, H(U)1 TO H(U)6, J(W)59, K(X)1 TO K(X)5, K(X)55 TO K(X)56 AND M(Z)44 TO M(Z)46 IS NOISY AND VERY POOR. THOSE RESIDUES CANNOT BE MODELLED. | |
