In cells infected with adenovirus type 5 temperature-sensitive mutants ts 17 and ts 20, hexon polypeptides (monomers) synthesized at 38.5 do not assemble into capsomeres (trimers) at that temperature. Although hexon polypeptides newly synthesized at the nonpermissive temperature assemble on temperature stepdown, holding the polypeptides at 38.5 for 2 hr before stepdown to 32.5 decreases assembly by 65-75%. Structural studies of wt and ts mutants have shown that the hexon polypeptides are identical in molecular weight, as well as tryptic and chymotryptic peptide patterns. These observations suggest that genes other than those coding for the primary structure of the hexon polypeptide are important for in vivo assembly of hexon. 1975.
