The chemical reactions and pathways resulting in the breakdown of glutamate into succinate, that includes the conversion of 4-aminobutyrate to succinate semialdehyde by the pyruvate-dependent gamma aminobutyrate (GABA) transaminase.
Comment:
While mammals only have 2-oxoglutarate-dependent GABA-transaminase, both 2-oxoglutarate-dependent and pyruvate-dependent GABA-transaminase activities have been detected in plants.
