Cloned(Commentary)

EC Number Cloned (Comment) Organism
3.1.1.11 recombinant expression of wild-type enzyme and mutants in Nicotiana benthamiana leaves via the Agrobacterium tumefaciens strain GV3101 transfection method, quantitative RT-PCR enzyme expression analysis Arabidopsis thaliana

Protein Variants

EC Number Protein Variants Comment Organism
3.1.1.11 additional information analysis of allelic T-DNA insertional KO mutants of the enzyme, pme31-1 (SALK_074820) and pme31-2 (CS25163). The pme31 mutants are more sensitive to Na+ toxicity than the wild-type, the mutations in PME31 lead to salt hypersensitive phenotypes, overview. The cotyledon greening rate of pme31 mutants are significantly lower in the presence of NaCl and NaNO3, but not in the presence of KCl, KNO3, and osmotic stress, pme31 mutants are only sensitive to Na+ toxicity Arabidopsis thaliana
