Biochemical identification of a tryptophan auxotroph in Rhodospirillum rubrum.

Abstract:

:A tryptophan auxotroph of aerobically grown Rodospirillum rubrum was isolated after mutagenesis and replica plating. The mutant grows on tryptophan or indole, accumulates indole glycerol phosphate, lacks the capacity to convert indole glycerol phosphate to indole glycerol phosphate to indole, and finally is defective in photosynthetic growth. The strain is, therefore, analogous to a Trp A mutant which is defective in the alpha-subunit structural gene of tryptophan synthetase.
