The Photorespiratory Nitrogen Cycle showing the alternative route through tartronic semialdehyde. The ammonia produced in the conversion of glycine to serine passes out of the mitochondrion and is reassimilated (green pathway). The CO2 released in the mitochondrion escapes to the intercellular spaces. The red pathway represents the intended short-circuit in the photorespiratory cycle by the bacterial enzymes gcl and hyi. Figure adapted from Wingler et al. [39] and Keys et al. [1]. (Glu: Glutamate; Gln: Glutamine; 2OG: 2-oxoglutarate; OAA: oxaloacetate; TSA tartronic semialdehyde).
