abstract：:Transamination between γ-aminobutyrate and α-ketoglutarate provides a pathway for the utilization of γ-aminobutyrate in fruit-bodies of Agaricus bisporus Lge. This reaction leads to the formation of succinic semialdehyde, a metabolic intermediate in the metabolism of γ-aminobutyrate to succinate in the cell. γ-aminobu...
