From physiological and antibiotic tests, we can conclude these four mutants are independent. However, they can be grouped into two categories according to the cross-feeding data and growth tests: Two were partially blocked on tryptophan synthetase, and the other two were inhibited before indole-glycerol phosphate formation.
