Cloning, sequencing, and molecular analysis of the dnaK locus from Bacillus subtilis.

By using an internal part of the dnaK gene from Bacillus megaterium as a probe, a 5.2-kb HindIII fragment of chromosomal DNA of Bacillus subtilis was cloned. Downstream sequences were isolated by in vivo chromosome walking. Sequencing of 5,085 bp revealed four open reading frames in the order orf39-grpE-dnaK-dnaJ. orf39 encodes a 39-kDa polypeptide of… (More)
