A particular characteristic of plant aspartic proteinases is the presence of an approximately 100 amino-acids long insertion, highly homologous to both saposins and saposin-like proteins and whose physiological function is currently unknown – the Plant Specific Insert (PSI). This PSI domain is characterized by a closely packed globular structure comprised by five amphipathic α-helices linked to each other by th...
In this work, Ni nanoparticles were obtained by laser ablation of a Nickel target with femtosecond pulses from a Ti-Sapphire laser in an aqueous media. Subsequently, these nanoparticles were isolated and covered with TiO2.
