Two Arabidopsis Threonine Aldolases Are Nonredundant and Compete with Threonine Deaminase for a Common Substrate Pool

Vijay Joshi; Karen M. Laubengayer; Nicolas Schauer; et al. The Plant Cell 2006. doi:10.1105/tpc.106.044958

Other claims from this paper (9)

Observation THA1 is expressed primarily in seeds and seedlings.
Observation THA2 is expressed in vascular tissue throughout the plant.
Observation tha1 mutants had more than a 50-fold increase in seed threonine content.
Observation tha1 mutants had few other significant metabolic changes.
Observation Homozygous tha2 mutations caused a lethal albino phenotype.
Intervention effect Feedback-insensitive Thr deaminase rescued tha2 mutants and tha1 tha2 double mutants.
Mechanism The rescue indicates THA1- and THA2-mediated glycine formation is dispensable.
Intervention effect Seed-specific feedback-insensitive Thr deaminase expression greatly increased seed Ile content in both aldolase mutants.
Mechanism The two threonine catabolic enzymes likely compete for a common substrate pool.
