For many years scientist realized that Nature offers astonishing examples for original inspiration. In particular, macromolecules found in any life form, and used as structural or functional purposes, have encouraged the development of innovative and unconventional synthetic polymeric counterparts that could be employed in many fields, including biomedicine, energy, environmental or high-performance materials. The unique properties found in polysaccharides, proteins or nucleic acids and the fundamental understanding of the origins of such behaviours have lead to the progress of the synthesis of novel macromolecular-based systems exhibiting useful properties, including self-assembling capability, stimuli-responsiveness, augmented properties (mechanical, adhesion, extreme wettability, self-healing), highly-specific bio-recognition or multifunctional character. Such materials can be also assembled at different length-scales and shapes to produce devices for multiple-applications.

Abstract: The ability of a CE2 glucomannan acetyl esterase from Clostridium thermocellum to catalyze acyl transfer to various natural mono- and polysaccharides was investigated. The transesterification reactions were carried out in two-phase mixtures consisted of water/vinyl esters that were also played the role of the acyl donors. The esterase preferred the acylation of d-glucose, d-mannose and d-galactose to the corresponding n-propyl and n-butyl esters, exhibiting strict regioselectivity at O-6 position. This acylation potential was also proved successful for the decoration of various polysaccharides that contain the aforementioned sugars, such as glucomannan, galactomannan, -glucan and lichenan.
