recombinant slr0156 protein, derived from Synechocystis PCC 6803 strain slr0156 sequence. This protein is annotated as ClpB1 in a data base but was originally named ClpB2 according to the paper of Giese and Vierling (2002).
ClpB2 is essential for organism and can not be complemented by a mutation in ClpB1 gene. This cytoplasmic protein is not involved in thermotolerance. Giese and Vierling (2002) Changes in oligomerization are essential for the chaperone activity of a small
