OBSOLETE. Catalysis of the reaction: ATP + H2O = ADP + phosphate. The hydrolysis of ATP involved in maintaining an unfolded polypeptide structure before folding or to entry into mitochondria and chloroplasts.

OBSOLETE. Assists in chromatin assembly by chaperoning histones on to replicating DNA, but is not a component of the assembled nucleosome when performing its normal biological function.

OBSOLETE. Assists in the correct, non-covalent assembly of glycoproteins in vivo, but is not a component of the assembled structures when performing its normal biological function. Utilizes a lectin site as a means to associate with the unfolded glycoproteins.

Catalysis of the rearrangement of both intrachain and interchain disulfide bonds in proteins.

Catalysis of the reaction: peptidyl-proline (omega=180) = peptidyl-proline (omega=0).

OBSOLETE. Assists in the correct non-covalent assembly of polypeptide-containing structures in vivo, but is not a component of these assembled structures when they are performing their normal biological function.

OBSOLETE. (Was not defined before being made obsolete).

Functions in chain elongation during polypeptide synthesis at the ribosome.
