DNA Polymerase III

Synonyms

DNA Dependent DNA Polymerase III

DNA Pol III

DNA Polymerase delta

DNA-Dependent DNA Polymerase III

Polymerase III, DNA

Polymerase delta, DNA

A DNA-dependent DNA polymerase characterized in E. coli and other lower organisms but may be present in higher organisms. Use also for a more complex form of DNA polymerase III designated as DNA polymerase III* or pol III* which is 15 times more active biologically than DNA polymerase I in the synthesis of DNA. This polymerase has both 3'-5' and 5'-3' exonuclease activities, is inhibited by sulfhydryl reagents, and has the same template-primer dependence as pol II. EC 2.7.7.7.
