Identification and cloning of genes involved in anaerobic sulfite reduction by Salmonella typhimurium.

Transposon Tn5 insertions causing anaerobic cysteine auxotrophy were isolated from a Salmonella typhimurium cysI parent (auxotrophic under aerobic but not anaerobic conditions). Insertions in one mutant group appeared to be in cysG. A second group of insertions, designated asr (anaerobic sulfite reduction), were located near map unit 53 on the S. typhimurium chromosome. They did not cause aerobic or anaerobic auxotrophy in a cys1+ background but did prevent dissimilatory sulfite reduction. Plasmids containing asr DNA cloned from wild-type S. typhimurium conferred anaerobic prototrophy and the ability to produce hydrogen sulfide from sulfite on an Escherichia coli cys1 mutant.[1]
