Porcine kidney 18 kD peptidyl-prolyl cis-trans isomerase (PPIase) belongs to the cyclophilin family that is inhibited by the immunosuppressive drug cyclosporin A. The chaperone activity of PPIase was studied using inactive, active, and alkylated PPIase during rabbit muscle creatine kinase (CK) refolding. The results showed that low concentration inactive or(More)
Trk/Ktr/HKT transporters probably were evolved from simple K+ channels KcsA. HKT transporters, which mediate Na+-uniport or Na+/K+-symport, maintain K+/Na+ homeostasis and increase salinity tolerance, can be classified into three subfamilies in higher plants. In this review, we systematically analyzed the characteristics of amino acids sequences and(More)
BACKGROUND Indole-3-acetic acid (IAA) extraction and purification are of great importance in auxin research, which is a hot topic in the plant growth and development field. Solid-phase extraction (SPE) is frequently used for IAA extraction and purification. However, no IAA-specific SPE columns are commercially available at the moment. Therefore, the(More)
Brassinosteroids (BRs) are steroidal phytohormones that regulate various physiological processes, such as root development and stress tolerance. In the present study, we showed that brassinolide (BL) affects potato root in vitro growth in a dose-dependent manner. Low BL concentrations (0.1 and 0.01 μg/L) promoted root elongation and lateral root(More)
KUP/HAK/KT transporters mainly play a role of K+ uptake in plants. PaHAK1 was a previously isolated KUP/HAK/KT transporter gene from a high K+ plant Phytolacca acinosa Roxb. In this study, we want to identify the function of PaHAK1. PaHAK1 was overexpressed in eukaryotes including Arabidopsis, rice, and yeast. The growth and K+ uptake of transgenic lines in(More)
The effect of Mg2+ on the thermal inactivation and unfolding of rabbit muscle creatine kinase has been studied for various temperatures and Mg2+ concentrations. Increasing the Mg2+ concentration in the denatured system significantly enhanced the inactivation and unfolding of creatine kinase during thermal denaturation. The analysis of the kinetic course of(More)
