Sm. Phang et al., CLONING AND COMPLETE SEQUENCE OF THE DNA POLYMERASE-ENCODING GENE (BSTPOLI) AND CHARACTERIZATION OF THE KLENOW-LIKE FRAGMENT FROM BACILLUS-STEAROTHERMOPHILUS, Gene, 163(1), 1995, pp. 65-68
A fragment of the DNA polymerase I-encoding gene (polI) from Bacillus
stearothermophilus (Bst) was obtained by PCR. This was used as a probe
to obtain a full-length gene from a Bst genomic DNA (gDNA) plasmid li
brary. Comparison of the sequence to B. caldotenax (Bca) showed about
93% homology at the amino acid (aa) level. A Klenow-like (BstpolIk) cl
one was developed and the recombinant protein displayed DNA polymerase
activity similar to the wild-type BstPolI enzyme.
