 Alanine accumulation under anaerobic stress - Aminotransferase Reactions - HORT640 - Metabolic Plant Physiology - ...
The precise function of alanine accumulation under anoxia is unknown, but it is speculated that it may serve as a storage form of pyruvate (perhaps in the vacuole), controlling supply of pyruvate to LDH and PDC, and hence flux to lactate and ethanol (Good and Crosby, 1989; Good and Muench, 1992).
The synthesis of alanine may occur at the expense of the acidic amino acids, glutamate and aspartate (Streeter and Thompson, 1972; Stewart and Larher 1980), and occurs concomitantly with the accumulation of 4-aminobutyrate or gamma-aminobutyrate (GABA) (Streeter and Thompson, 1972; Stewart and Larher, 1980; Wallace et al, 1984; Ratcliffe, 1995).
