Differential Expression of Arabidopsis thaliana Acid Phosphatases in Response to Abiotic Stresses
The objective of this research is to identify Arabidopsis thaliana genes encoding acid phosphatases induced by phosphate starvation. Multiple alignments of eukaryotic acid phosphatase amino acid sequences led to the classification of these proteins into four groups including purple acid phosphatases (PAPs). Specific primers were degenerated and designed based on conserved sequences of PAPs isol...

متن کاملFunctional Assessment of an Overexpressed Arabidopsis Purple Acid Phosphatase Gene (Atpap26) in Tobacco Plants
Background: Overexpression of known genes encoding key phosphate (Pi)-metabolizing enzymes, such as acid phosphatases (APases), is presumed to help plants with Pi availability and absorption as they are mostly exposed to suboptimal environmental conditions for this vital element.Objectives: In this study, the overexpression effect of AtPAP26, one of the m...
متن کاملPlant purple acid phosphatases - genes, structures and biological function.
The properties of plant purple acid phosphatases (PAPs), metallophosphoesterases present in some bacteria, plants and animals are reviewed. All members of this group contain a characteristic set of seven amino-acid residues involved in metal ligation. Animal PAPs contain a binuclear metallic center composed of two irons, whereas in plant PAPs one iron ion is joined by zinc or manganese ion. Amo...
متن کاملDiesterase activity and substrate binding in purple acid phosphatases.
Purple acid phosphatases (PAPs) are dinuclear monoesterases1,2 that are structurally diverse but with a conserved set of ligands to the Fe3+-M2+ metal centers (M2+ ) Fe, Zn, or Mn).3 The identity of the nucleophile and the substrate binding mode have been matters of controversy (Figure 1).1,3-5 In one proposal, substrate binds to the divalent metal and is attacked by a terminal Fe3+-bound hydro...
