ABZ1

Functionⁱ

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.1 Publication

Miscellaneous

Present with 1550 molecules/cell in log phase SD medium.1 Publication

Catalytic activityⁱ

Chorismate + L-glutamine = 4-amino-4-deoxychorismate + L-glutamate.

Pathwayⁱ: tetrahydrofolate biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes 4-aminobenzoate from chorismate.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:

Aminodeoxychorismate synthase (ABZ1)
Aminodeoxychorismate lyase (ABZ2)

This subpathway is part of the pathway tetrahydrofolate biosynthesis, which is itself part of Cofactor biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes 4-aminobenzoate from chorismate, the pathway tetrahydrofolate biosynthesis and in Cofactor biosynthesis.
