Plant Physiology published a research study entitled, “Malate-Induced Hysteresis of Phosphoenolpyruvate Carboxylase from Crassula Argentea”, conducted by Apinya Ngam-ek, Thomas Seery, Eric Amis and Sott Grover. Dynamic light scattering measurements performed with a Brookhaven BI-200SM Goniometer were used in this research to investigate the hysteric behavior of phosphoenolpyruvate (PEP) carboxylase from Crassula argentea.
Findings of this paper presented evidence to support the claim that PEP carboxylase hysteresis from Crassula argentea was due to sub-unit association-dissociation and showed how this behavior depended on certain ligands and conditions. The dynamic light scattering measurements performed with Brookhaven’s BI-200SM Goniometer demonstrated the slow decrease of the malate-incubated enzyme’s diffusion coefficient after the reaction was started by the addition of PEP.
Dynamic light scattering is a technique widely used in scientific advances and innovations. Scientists and researchers utilize effective particle size analyzers to determine dynamic light scattering measurements of small particles and polymers. Brookhaven Instruments carries a sophisticated line of technologically advanced particle size analyzers, including the BI-200SM Goniometer.
