Anthranilate phosphoribosyltransferase; Catalyzes the transfer of the phosphoribosyl group of 5- phosphorylribose-1-pyrophosphate (PRPP) to anthranilate to yield N-(5'- phosphoribosyl)-anthranilate (PRA).

The N-(5'-phosphoribosyl)anthranilate isomerase (PRAI) converts the N-(5-phospho-beta-D-ribosyl)anthranilate to 1-(2-carboxyphenylamino)-1-deoxy-D-ribulose 5-phosphate, the third step in the biosynthesis of tryptophan; Localized in the cytoplasm; High confidence in function and specificity; Belongs to the TrpF family.

Tryptophan synthase beta subunit; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine.

Tryptophan synthase, alpha subunit; The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate. Belongs to the TrpA family.

The anthranilate synthase catalyzes the formation of anthranilate from chorismate and L-glutamine, the first step in the biosynthesis of tryptophan. The enzyme is a Tetramer of two components I and two components II. The component I only catalyzes the formation of anthranilate using chorismate and ammonia rather than glutamine; The anthranilate synthase is regulated by feedback inhibition by tryptophan; Belongs to the anthranilate synthase component I family; Localized in the cytoplasm; High confidence in function and specificity.

Anthranilate synthase component II (glutamine amidotransferase); The anthranilate synthase catalyzes the formation of anthranilate from chorismate and L-glutamine, the first step in the biosynthesis of tryptophan. The enzyme is a Tetramer of two components I and two components II. Associated with the component I, the component II of the anthranilate synthase provides the glutamine amidotransferase activity (GATase, 2.4.2.-) that catalyses the removal of the ammonia group from a glutamate molecule and its subsequent transfer to a specific substrate, thus creating a new carbon-nitrogen g [...]

Anthranilate synthase component I-like protein; Enzyme that contains a C-terminal chorismate binding domain and belonging to the anthranilate synthase component I family; Localized in the cytoplasm; Family membership.

Involved in molybdenum cofactor biosynthesis, MoaC, a small hexameric protein, converts, together with MoaA, a guanosine derivative to the precursor Z by inserting the carbon-8 of the purine between the 2' and 3' ribose carbon atoms, which is the first of three phases of molybdenum cofactor biosynthesis; Localized in the cytoplasm; High confidence in function and specificity.

The isochorismate synthase, called also isochorismate mutase catalyses the conversion of chorismate to isochorismate, the first step in the biosynthesis of both respiratory chain components: menaquinone (MK, vitamin K2) and phylloquinone (vitamin K1); Localized in the cytoplasm; High confidence in function and specificity.
