In vitro RNA-dependent RNA Polymerase Assay Using Arabidopsis RDR6
[Abstract]  RNA-dependent RNA polymerases (RdRPs) in eukaryotes convert single-stranded RNAs into double-stranded RNAs, thereby amplifying small interfering RNAs that play crucial roles in the regulation of development, maintenance of genome integrity and antiviral immunity. Here, we describe a method of in vitro RdRP assay using recombinant Arabidopsis RDR6 prepared by an insect expression system. By using this classical biochemical assay, we revealed that RDR6 has a strong template ...

Measurement of ATP Hydrolytic Activity of Plasma Membrane H+-ATPase from Arabidopsis thaliana Leaves
[Abstract]  Plant plasma membrane H+-ATPase, which is a P-type ATPase, couples ATP hydrolysis to H+ extrusion and thereby generates an electrochemical gradient across the plasma membrane. The proton gradient is necessary for secondary transport, cell elongation, and membrane potential maintenance. Here we describe a protocol for measurement of the ATP hydrolytic activity of the plasma membrane H+-ATPase from Arabidopsis thaliana leaves.

Purification of a Protein Exhibiting Isoleucine 2-epimerase Activity from Lactobacillus otakiensis JCM 15040
[Abstract]  Prominent accumulation of D-leucine, D-allo-isoleucine and D-valine was observed in the culture medium of the heterofermentative bacterial species, Lactobacillus otakiensis (L. otakiensis) JCM 15040. The racemase enzyme that resulted in this accumulation, isoleucine 2-epimerase, was purified from the bacterial cells. This is the first reported observation of such production of D-branched chain amino acids in lactic acid bacteria, and the first example of a racemase ...
