Remark 999 | SEQUENCE NUCLEOTIDES 1001B TO 1014B BELONG TO AN ENGINEERED U1A LOOP AND ARE INSERTED BETWEEN GUA- ...SEQUENCE NUCLEOTIDES 1001B TO 1014B BELONG TO AN ENGINEERED U1A LOOP AND ARE INSERTED BETWEEN GUA-107B AND CYT-112B. THERE ARE NO NUCLEOTIDES BETWEEN GUA-1B AND GUA-5B DUE TO A CLONING DESIGN. O2' OF DEOXY MODIFICATION OF RNA NUCLEOTIDES ARE INCLUDED WITH Q=0.00 AND B=0.00. THEY ARE AT GUA-206C, CYT-1C, CYT-205C, AND THY-1D. CHAINS B AND C ARE TWO PARTS OF THE ORIGINAL ONE INTRON SEQUENCE BECAUSE OF AN EXPERIMENTAL DESIGN. THE U1A PROTEIN USED IN THIS STUDY WAS A DOUBLE MUTANT IN WHICH TYR-31/GLN-36 WAS REPLACED WITH HIS-31/ARG-36. THE FIRST THREE RESIDUES IN U1A PROTEIN WERE MISSING IN THE STRUCTURE. |
