LOOP 140-150 IN PROTOMER J (NO CALCIUM) IS LOOSELY ASSOCIATED WITH MAIN BODY OF PROTEIN. IT FORMS SYMMETRY CONTACT TO PROTOMER I WITH GLU 147 J CHELATING TO CALCIUM IONS IN PROTOMER I. LOOP 140-150 IN PROTOMER D (NO CALCIUM) IS LOOSELY ASSOCIATED WITH MAIN BODY OF PROTEIN. IT FORMS SYMMETRY CONTACT TO PROTOMER C WITH GLU 147 D CHELATING TO CALCIUM IONS IN PROTOMER C. THE UNCERTAINTY IN RESIDUES 142 - 145 IN CHAINS D AND J RESULTS IN 2.4 A CLOSE NON-BONDED CONTACTS D 142 - D 143 AND J 142 - J 143. RESIDUE LEU 43 IN CHAINS D AND J FALLS IN A GENEROUSLY ALLOWED POSITION ON THE RAMACHANDRAN PLOT. THIS MINOR UNCERTAINTY IN THIS REGION IN PROTOMERS D AND J RESULTS IN TWO 2.6 A NON-BONDED CONTACTS IN EACH PROTOMER (D 42 - D 43, D 44 - D 45 , J 42 - J 43, J 44 - J 45).
