Unexpected Arabinosylation after Humanization of Plant Protein -Glycosylation.

As biopharmaceuticals, recombinant proteins have become indispensable tools in medicine. An increasing demand, not only in quantity but also in diversity, drives the constant development and improvement of production platforms. The -glycosylation pattern on biopharmaceuticals plays an important role in activity, serum half-life and immunogenicity.

Stable Protein Sialylation in Physcomitrella.

Recombinantly produced proteins are indispensable tools for medical applications. Since the majority of them are glycoproteins, their -glycosylation profiles are major determinants for their activity, structural properties and safety. For therapeutical applications, a glycosylation pattern adapted to product and treatment requirements is advantageous.

A red light-controlled synthetic gene expression switch for plant systems.

On command control of gene expression in time and space is required for the comprehensive analysis of key plant cellular processes. Even though some chemical inducible systems showing satisfactory induction features have been developed, they are inherently limited in terms of spatiotemporal resolution and may be associated with toxic effects. We describe here the first synthetic light-inducible system for the targeted control of gene expression in plants.
