A ribosome-associating chaperone mediates GTP-driven vectorial folding of nascent eEF1A

The paper identifies Ypl225w as a chaperone that facilitates GTP-driven co-translational folding of eEF1A by interacting with the ribosome and NAC.

The importomer is a peroxisomal membrane protein translocase

The paper identifies the importomer as the peroxisomal translocase responsible for integrating membrane proteins, showing it operates without substrate unfolding.
