BECAUSE THE *A* AND REMARK 5 *B* CHAINS RUN IN OPPOSITE DIRECTIONS, THE TWELVE REMARK 5 NUCLEOTIDES GENERATED BY ADDING 44.58 TO Z FOR THE *A* REMARK 5 CHAIN SHOULD BE INSERTED AFTER THE TWELVE NUCLEOTIDES REMARK 5 OF THE *A* CHAIN PRESENT IN THIS ENTRY, WHILE THE TWELVE REMARK 5 NUCLEOTIDES GENERATED BY ADDING 44.58 TO Z FOR THE *B* REMARK 5 CHAIN SHOULD BE INSERTED BEFORE THE TWELVE NUCLEOTIDES REMARK 5 OF THE *B* CHAIN PRESENT IN THIS ENTRY. REMARK 6 REMARK 6 THIS ENTRY INCLUDES HYDROGEN ATOMS. EACH HYDROGEN ATOM HAS REMARK 6 BEEN ASSIGNED A NAME IN WHICH THE THIRD AND FOURTH REMARK 6 CHARACTERS REPRESENT THE NUMBER WITHIN THE RESIDUE REMARK 6 (NUCLEOTIDE) OF THE NON-HYDROGEN ATOM TO WHICH IT IS REMARK 6 BONDED. IN THE CASE OF MORE THAN ONE HYDROGEN ATOM BONDED REMARK 6 TO THE SAME NON-HYDROGEN ATOM, THE FIRST CHARACTER OF THE REMARK 6 NAME OF THE HYDROGEN ATOM IS ASSIGNED A NUMBER (1, 2, ...). REMARK 6 FOR EXAMPLE, IN THE NUCLEOTIDE C A 1 THERE ARE TWO HYDROGEN REMARK 6 ATOMS BONDED TO ATOM C5*. BECAUSE ATOM C5* IS THE FIFTH REMARK 6 ATOM IN THIS RESIDUE (NUCLEOTIDE), THE HYDROGEN ATOMS HAVE REMARK 6 BEEN ASSIGNED THE NAMES 1H 5 AND 2H 5. WITHIN A RESIDUE REMARK 6 (NUCLEOTIDE) THE NON-HYDROGEN ATOMS WILL BE LISTED FIRST, REMARK 6 FOLLOWED BY THE HYDROGEN ATOMS IN ASCENDING ORDER.
