ABSTRACT
Molecular chaperones play essential roles in protein quality control in the cell. Among molecular chaperones, ve protein families are recognized as highly conserved, and ubiquitously distributed [1-3]. They are small Hsp, chaperonin or Hsp60 (GroEL), Hsp70 (DnaK), Hsp90 (HtpG), and Hsp104 (ClpB) (Table 5.1). GroEL, DnaK, HtpG, and ClpB are terms normally used for prokaryotic members. The chaperone families include members whose expression is constitutive and others that are responsive to heat and/or other stresses.
