Photoadduct formation requires ribosome-bound nascent chains. Translocation intermediates containing a cryptic glycosylation sequence in their nascent chains were incubated without (lanes 1–4) or with (lanes 5–8) puromycin before photolysis. The asterisk identifies photoadducts containing the 60–70-kD protein. Radioactive species are identified as in Fig. 1.
