Educational reconstruction of size-depended-properties in nanotechnology for teaching in tertiary education

Abstract (Expand)

There is an overarching theme in Science Education to integrate in the school and university curriculum interdisciplinary state-of-art innovations. The field of Nanotechnology is such an example, because … it combines the aforementioned interdisciplinarity and novelty with a well-documented educational value. Herein, a novel teaching approach concerning size-dependent properties at the nanoscale for chemistry and physics undergraduate students is proposed. The analysis of the scientific content and its following reconstruction for teaching purposes is based on the theoretical framework of the Model of Educational Reconstruction (MER). This analysis yielded two fundamental concepts and a series of activities that can be the main core of teaching Nanotechnology at a university level.

Rational engineering of Luminiphilus syltensis ( R )-selective amine transaminase for the acceptance of bulky substrates

Abstract (Expand)

Despite the plethora of information on (S)-selective amine transaminases, the (R)-selective ones are still not well-studied; only a few structures are known to the day, and their substrate scope is … limited, apart from a few stellar works on the field. Herein, Luminiphilus syltensis (R)-selective amine transaminase’s structure was elucidated to facilitate the engineering towards variants active on bulkier substrates. V37A variant led to increased activity towards 1-phenylpropylamine and to activity against 1-butylamine. On the contrary, S248 and T249 positions, located on the β-turn in P-pocket, seem crucial for maintaining enzyme’s activity.
