Protein attributes

Sequence length	787 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Catalyzes the biosynthesis of 4-amino-4-deoxychorismate (ADC) from chorismate and glutamine. Required for the synthesis of 4-aminobenzoate (PABA), an important component in tetrahydrofolate biosynthesis.
Catalytic activity	Chorismate + L-glutamine = 4-amino-4-deoxychorismate + L-glutamate.
Pathway	Cofactor biosynthesis; tetrahydrofolate biosynthesis; 4-aminobenzoate from chorismate: step 1/2.
Subcellular location	Cytoplasm.
Domain	The PABA component provides the glutamine amidotransferase activity. The PABB component catalyzes the formation of ADC by binding chorismate and ammonia.
Miscellaneous	Present with 1550 molecules/cell in log phase SD medium.
Sequence similarities	In the C-terminal section; belongs to the anthranilate synthase component I family. Contains 1 glutamine amidotransferase type-1 domain.
Sequence caution	The sequence AAA34840.1 differs from that shown. Reason: Frameshift at positions 581, 586, 591, 716, 729 and 734. The sequence AAB49319.1 differs from that shown. Reason: Frameshift at positions 581, 586 and 591.
