DNA Polymerase III MeSH Descriptor Data 2022


MeSH Heading
DNA Polymerase III
Tree Number(s)
D08.811.913.696.445.308.300.235
Unique ID
D004258
RDF Unique Identifier
http://id.nlm.nih.gov/mesh/D004258
Scope Note
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.
