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