EFFECT OF 6-AMINONICOTINAMIDE ON CHICK-EMBRYO TISSUE CULTURES INFECTED WITH VACCINIA VIRUS.

abstract：:Sixty-four mutants were isolated from the LT-2 wild-type strain of Salmonella typhimurium by selecting for chromate resistance. The majority of lesions were shown to lie in the cysA gene. (i) The mutants cannot take up sulfate, a finding which verifies the role of cysA in sulfate transport. In addition, 52 sulfate-tra...
