Low molecular mass heat-shock proteins of a light-resistant photoautotrophic cell culture

G Knack et al. Eur J Cell Biol. 1992 Oct.

Abstract

Two low molecular mass heat-shock proteins (HSPs) of photoautotrophic cell culture (Chenopodium rubrum) have been cloned, sequenced and compared to published sequences. One of these HSPs (23.3 kDa) is posttranslationally transported into chloroplasts and shares homology with the other heat-shock proteins in the last third C-terminal region of the protein, but has a relatively unique sequence in the other two thirds. The correspondent small cytosolic protein of 18.3 kDa is related to all known small HSPs but has a unique DNA-binding domain that has not been described so far in the group of small cytosolic HSPs, it might represent a HSP which is translocated into the nucleus.
