Protein Variants

Protein Variants Comment Organism
additional information construction of a T-DNA insertion mutant that shows a fivefold reduction in transcript, reduced TPI activity, and a severely stunted and chlorotic seedling that accumulates dihydroxyacetone phosphate, glycerol, and glycerol-3-phosphate. Methylglyoxal, a by-product of dihydroxyacetone phosphate, also accumulated in the pdtpi mutant. Lipid profiling reveals lower monogalactosyl but higher digalactosyl lipids in the mutant compared to the wild-type, phenotype, overview. Exogenous glycolytic intermediates do not rescue the pdtpi phenotype. Metabolic pathways affected by a mutation in pdTPI during postgerminative seedling transition from heterotrophic to photoautotrophic development, overview Arabidopsis thaliana
