Protein

DNA polymerase III subunit gamma/tau

Gene

dnaX

Organism
Mycoplasma pneumoniae (strain ATCC 29342 / M129)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. This DNA polymerase also exhibits 3' to 5' exonuclease activity.

Catalytic activityi

Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1).

Interactioni

Subunit structurei

DNA polymerase III contains a core (composed of alpha, epsilon and theta chains) that associates with a tau subunit. This core dimerizes to form the POLIII' complex. PolIII' associates with the gamma complex (composed of gamma, delta, delta', psi and chi chains) and with the beta chain to form the complete DNA polymerase III complex By similarity.By similarity
