chaperone protein names
DnaK: the recommended name is Chaperone protein DnaK; the alternative names are HSP70, Heat shock 70 kDa protein, and Heat shock protein 70 (source: UniProtKB); the name of the protein, DnaK, is derived from the name of the gene, dnaK (Yochem et al., 1978, Mol Gen Genet. 164: 9-14):


  We show that a collection of 93 E. coli mutations which map between
  thr and leu and which block phage lambda DNA replication define two
  closely linked cistrons. Work published in the accompanying paper
  shows that these mutations also affect host DNA replication, so we
  designate them dnaJ and dnaK; the gene order is thr--dnaK--dnaJ--leu.
