Tryptophan-grown cells of Bacillus megaterium ATCC 19213 contain a permease system that transports both D- and L-tryptophan and is inhibited by sodium azide. Arginine-grown cells contain little tryptophan permease activity, suggesting that the system is inducible. Arginine represses the tryptophan permease as well as the transport system for leucine and phenylalanine. Kynurenine was a more effective inducer of the tryptophan transport system than either D- or L-tryptophan.
巨大芽孢杆菌ATCC 19213在色氨酸培养基中生长的细胞含有一种通透酶系统,该系统可转运D-色氨酸和L-色氨酸,且受叠氮化钠抑制。在精氨酸培养基中生长的细胞几乎没有色氨酸通透酶活性,这表明该系统是可诱导的。精氨酸会抑制色氨酸通透酶以及亮氨酸和苯丙氨酸的转运系统。犬尿氨酸比D-色氨酸或L-色氨酸更能有效诱导色氨酸转运系统。
