An alpha-like DNA polymerase from Halobacterium halobium. 1985

M Nakayama, and M Kohiyama

Two DNA polymerases have been isolated from extracts of Halobacterium halobium, one having a sedimentation coefficient of 11 S, designated as alpha-like polymerase and possessing the following characteristics. It is sensitive to both aphidicolin and N-ethylmaleimide but indifferent to the presence of a dideoxynucleoside triphosphate. Therefore this polymerase is very similar to the alpha DNA polymerase of eukaryotes. The enzyme requires 5 M NaCl for maximum activity. The other polymerase has a sedimentation coefficient of 4.4 S and is resistant to both aphidicolin and N-ethylmaleimide. However, it is inhibited by a dideoxynucleoside triphosphate.

D004257	DNA Polymerase II	A DNA-dependent DNA polymerase characterized in E. coli and other lower organisms. It may be present in higher organisms and has an intrinsic molecular activity only 5% of that of DNA Polymerase I. This polymerase has 3'-5' exonuclease activity, is effective only on duplex DNA with gaps or single-strand ends of less than 100 nucleotides as template, and is inhibited by sulfhydryl reagents.
