PCR amplification using the two degenerate primers for the sequences QATKDAG and NPDEAVA (see Materials and Methods).

Southern blotting with M. mazei dnaK as the probe.

ND, not done; + and −, presence and absence, respectively, of dnaK-related sequences.

Unpublished sequence; retrievable at http://www.bio.nite.go.jp/.

Organism whose dnaK has been cloned and sequenced.
