| 4.1.3.27 | chorismate + L-Gln |
anthranilate synthase activity of mutant plants resistant to growth inhition by 5-methyltryptophan is 2.2fold to 3fold higher than that of the control. OASE2 is one of the key-regulating enzyme subunits in the tryptophan biosynthetic pathway |
| 4.1.3.27 | chorismate + L-Gln |
feedback-insensitive enzyme |
| 4.1.3.27 | chorismate + L-glutamine |

| 4.1.3.27 | chorismate + L-glutamine |
one subunit of the enzyme contains a chorismate binding site and catalyzes the formation of anthranilate via 2-amino-2-deoxyisochorismate. After the first step, the intermediate remains bound to the enzyme, where it is subsequently converted to anthranilate through the elimination of pyruvate |
| 4.1.3.27 | chorismate + NH4+ |
feedback-insensitive enzyme |

| 4.1.3.27 | more |
synthesis of the enzyme is repressed by His, anthranilate, Trp and p-aminobenzoate |
| 4.1.3.27 | more |
Trp biosynthetic enzyme |
