FOR THE PURPOSES OF APPLYING NCS RESTRAINTS, EACH RNA REPEAT NEEDED TO BE GIVEN A DIFFERENT CHAIN ID. DUE TO A LACK OF LETTERS IN THE ALPHABET, RNA REPEATS THEREFORE HAD TO BE GIVEN THE SAME CHAIN ID AS THE CORRESPONDING PROTEIN MONOMER. RNA NUCLEOTIDES ARE NUMBERED 101-105 IN EACH OF CHAINS L-V. SIMILARLY, THE LREMARK 3 PROTEIN RESIDUES ARE NUMBERED 1-75 IN EACH CHAIN, A TO V, ALTHOUGH SOME N- AND C-TERMINAL RESIDUES ARE NOT VISIBLE DUE TO DISORDER. SOME PROTEIN SIDECHAIN ATOMS HAVE ZERO OCCUPANCY.
