I need some help with a metabolic pathway lab! [pictures included] I believe I've done this correct but would like some verification since this problem is worth quite a few points. I'm struggling with understanding how pathways work.

Here is the raw data of the substrates & enzymes: http://tinypic.com/r/i3b9qq/8
+ = growth, - = no growth. Substrates are the column going down, enzymes the top row.

My metabolic pathway looks like this:
Chorismate -- Anthranitic Acid -- Indole -- Tryptophan
^enzyme1,mutant:trpE^enzyme2,mutanttrpC, ^enzyme 3, mutant trp B

Thank you!
