Bacteriophage c6A is a lytic phage that infects strains of Streptococcus lactis. Infection of S. lactis C6 under standard conditions yielded 124 +/- 8 p.f.u. per infected cell after a latent period of 25 min at 30 degrees C. The virion of c6A was shown to contain at least 12 polypeptides and a 21.9 kilobase double-stranded, linear DNA genome with complementary 5'-protruding single-stranded termini. The (G + C) content of this DNA was estimated to be 36.7%. A restriction map was constructed which indicates that a number of restriction endonucleases did not digest the DNA and that others cleaved with a much lower frequency than expected.
噬菌体c6A是一种可感染乳酸链球菌菌株的裂解性噬菌体。在标准条件下，用c6A感染乳酸链球菌C6，在30℃下经过25分钟的潜伏期后，每个受感染细胞产生124±8个噬菌斑形成单位。已证明c6A病毒粒子含有至少12种多肽以及一个21.9千碱基的双链线性DNA基因组，其5'端具有互补的突出单链末端。该DNA的（G + C）含量估计为36.7%。构建了一个限制性图谱，结果表明一些限制性内切酶不能消化该DNA，而其他酶的切割频率比预期的要低得多。
