TL;DR: The molecular mass values for native and denatured protein were 100 and 49 kDa, respectively, suggesting that the active enzyme is a homodimer, and the addition of monovalent cations K+ and NH4+ stimulates BAMT activity by a factor of 2, whereas the added of Fe2+ and Cu2+ has a strong inhibitory effect.

TL;DR: Three types of magnesium-aluminum layered double hydroxides were synthesized and employed as solid-phase extraction (SPE) sorbents to extract several aromatic acids to be a fast and efficient procedure for the extraction of organic anions from aqueous samples.
Abstract: Three types of magnesium–aluminum layered double hydroxides were synthesized and employed as solid-phase extraction (SPE) sorbents to extract several aromatic acids (protocatechuic acid, mandelic acid, phthalic acid, benzoic acid, and salicylic acid) from aqueous samples. An interesting feature of these sorbents is that they dissolve when the pH of the solution is lower than 4. Thus, the analyte elution step, as needed in conventional sorbent-based extraction, was obviated by dissolving the sorbent in acid after extraction and separation from the sample solution. The extract was then directly injected into a high-performance liquid chromatography-ultraviolet detection system for analysis. In the key adsorption process, both dispersive SPE and co-precipitation extraction with the sorbents were conducted and experimental parameters such as pH, temperature, and extraction time were optimized. The results showed that both extraction methods provided low limits of detection (0.03–1.47 μg/L) and good linearity ...
