A POSSIBLE PHYSIOLOGICAL SUBSTRATE FOR POL BETA IS A DNA
GAP, WHERE THE LENGTH OF THE GAP CAN RANGE FROM ONE TO SIX
NUCLEOTIDES, AND THE DOWNSTREAM END OF THE DNA GAP IS

5'-PHOSPHORYLATED. IN ORDER TO CREATE VARIOUS GAPPED-DNA
SUBSTRATES FOR USE IN POL BETA-DNA CO-CRYSTALLIZATION
ATTEMPTS, THE AUTHORS HAD TO ANNEAL THREE DIFFERENT
OLIGONUCLEOTIDES TOGETHER PRIOR TO CRYSTALLIZATION:
(1) A RELATIVELY LONG (14 TO 20 MER) OLIGONUCLEOTIDE THAT
WAS TO SERVE AS THE TEMPLATE, (2) ONE SHORTER (5 OR 6 MER)
OLIGONUCLEOTIDE THAT WAS TO SERVE AS THE PRIMER, AND (3)
ANOTHER SHORTER (4 TO 10 MER) OLIGONUCLEOTIDE THAT WAS

5'-PHOSPHORYLATED AND WAS TO SERVE AS THE DOWNSTREAM
OLIGONUCLEOTIDE. DNA SEQUENCES CORRESPONDING TO THE
TEMPLATE, THE PRIMER, AND THE DOWNSTREAM OLIGONUCLEOTIDE
FOR THE CRYSTAL STRUCTURE PRESENTED HERE ARE:

5'-CATTAGAAAGGGAAGCGCCG-3' (20-MER), 5'-CGGCGC-3' (6-MER),

AND 5'-PO4-TCTAATG-3' (7-MER), RESPECTIVELY, WHERE "5'-PO4"

INDICATES THAT THE 5' TERMINUS OF THIS OLIGONUCLEOTIDE IS

5'-PHOSPHORYLATED. HOWEVER, AN UNEXPECTED POL BETA-DNA
COMPLEX RESULTED FROM THE CO-CRYSTALLIZATION ATTEMPTS SO
THAT WHAT WAS ORIGINALLY INTENDED TO BE THE

5'-PHOSPHORYLATED DOWNSTREAM OLIGONUCLEOTIDE IS BOUND
WHERE THE PRIMER STRAND WAS EXPECTED TO BIND (SEE REFERENCE
1). IN ADDITION, A MAJORITY OF THE GAPPED-DNA SUBSTRATE
(THAT IS, SIX BASE PAIRS OF TEMPLATE-PRIMER TETHERED TO A
FLEXIBLE, SINGLE-STRANDED DNA GAP) IS TOO DISORDERED TO BE
OBSERVABLE IN THE CRYSTAL STRUCTURE, ALTHOUGH IT IS
NEVERTHELESS THOUGHT TO BE PRESENT IN THE CRYSTAL LATTICE
(SEE REFERENCE 1). THE END RESULT IS THAT, ALTHOUGH THE
AFOREMENTIONED TEMPLATE IS STILL REFERRED TO AS THE
TEMPLATE IN THE STRUCTURES PRESENTED HERE, THE
AFOREMENTIONED "DOWNSTREAM OLIGONUCLEOTIDE" IS NOW CALLED
THE "PRIMER" -- BY ANALOGY WITH PREVIOUSLY REPORTED POL
BETA-DNA-DDCTP TERNARY COMPLEX STRUCTURES (SEE ENTRIES
2BPF AND 2BPG AND REFERENCE 8). ONLY THE DNA NUCLEOTIDES
THAT WERE VISIBLE IN THE STRUCTURE ARE INCLUDED IN THE
SEQRES SECTION BELOW.
