We obtained a mutant of bacteriophage T4 which overcame the deficiency in gene 49 endonuclease. The new mutation occurred in gene 32 and the mutant, which was viable, produced an amber fragment under non-suppressed conditions, lacking about 30 amino acid residues at the carboxyl terminus. Its growth, recombination, and resistance to UV irradiation were affected to various degrees by the particular suppressor tRNA present. Growth was increased by Su2^+ to nearly that of the wild type, but growth of all others was reduced in the presence and absence of suppressors, suggesting that the terminal domain of gene 32 protein is not indispensable for the function but modulates it. We discuss the mechanism by which the mutation overcomes the defect in gene 49 endonuclease.
