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.

Observation The deduced amino acid sequences of the flax PDCTs showed approximately 55% identity with A. thaliana PDCT (AtROD1).
Observation The two flax PDCT genes encoded functionally active enzymes.
Observation The flax PDCT genes were strongly expressed in developing embryos.
Intervention effect Complementation of the A. thaliana rod1 mutant showed that the flax PDCTs were capable of restoring PUFA levels in planta.
Intervention effect PUFA levels increased in Saccharomyces cerevisiae when the flax PDCTs were co-expressed with FAD2 and FAD3.
Intervention effect Seed-specific expression of LuPDCT1 in A. thaliana increased C18-PUFAs by 16.4%.
Intervention effect Seed-specific expression of LuPDCT2 in A. thaliana increased C18-PUFAs by 19.7%.
Mechanism The flax PDCT proteins appear to play a dual role in determining PUFA content.
Recommendation Flax PDCTs would be useful for bioengineering oil crops to increase PUFA levels.
