High-level overproduction of His-tagged Tth DNA polymerase in Thermus thermophilus

Appl Environ Microbiol. 2005 Jan;71(1):591-3. doi: 10.1128/AEM.71.1.591-593.2005.

Abstract

A new plasmid for the overexpression of His-tagged thermozymes in Thermus thermophilus was developed. With this plasmid, soluble and active histidine-tagged DNA polymerase from T. thermophilus was overproduced in larger amounts in the thermophile than in Escherichia coli. The protein purified from the thermophile was active in PCR.
