6.3.1.2 | physiological function | the rate-limiting step in photorespiration is the reassimilation of ammonia catalyzed by chloroplastic glutamine synthetase isozyme 2 (GS2). In plants, GS2 together with ferredoxin-dependent glutamate synthase (Fd-GOGAT) plays a major role in re-assimilation of ammonium liberated in mitochondria by the glycine decarboxylase, in the pathway known as glutamine synthetase/glutamate synthase (GS/GOGAT) cycle in chloroplasts. The product of this cycle, glutamate, is required for one of the peroxisomal transamination reactions | Hordeum vulgare |
