    Pathwayi: prephenate biosynthesis

    This protein is involved in step 1 of the subpathway that synthesizes prephenate from chorismate.
    Proteins known to be involved in this subpathway in this organism are:
    1. Chorismate mutase AroH (aroH), Chorismate mutase AroH (aroH), Protein AroA(G) (aroA)
    This subpathway is part of the pathway prephenate biosynthesis, which is itself part of Metabolic intermediate biosynthesis.
