Abstract: O-Methylation of N-acetylserotonin (NAS) has been identified as the bottleneck in melatonin biosynthesis pathway. In the present paper, caffeic acid O-methyltransferase from Arabidopsis thaliana (AtCOMT) was engineered by rational design to improve its catalytic efficiency… read more here.

Abstract: We have successfully visualized the surface terminal structure of polymer–metal complex [{Cu2(μ-Br)2(PPh3)2}(μ-bpy)]n nanocrystals (NCs) using Prussian blue (PB) nanoparticles (NPs). From TEM observation and analysis of the electron beam diffraction pattern, it was found that… read more here.
