GroEL-related molecular chaperones are present in the cytosol of oat cells.
In eukaryotic cells GroEL-related molecular chaperones (cpn 60) are considered to be restricted to plastids and mitochondria. Re-evaluation of the intracellular localization of chaperonins by electron microscopy, using two different anti-chaperonin antisera, revealed additionally their presence in the cytosol of oat primary leaf and coleoptile cells. The distribution of cpn 60 is not influenced by heat or light treatments.
