Alginate-modifying enzymes: biological roles and biotechnological uses

Alginate denotes a group of industrially important 1-4-linked biopolymers composed of the C-5-epimers β-D-mannuronic acid (M) and α-L-guluronic acid (G). The polysaccharide is manufactured from brown algae where it constitutes the main structural cell wall polymer. The physical properties of a given alginate molecule, e.g., gel-strength, water-binding capacity, viscosity and biocompatibility, a...

SnapShot: Histone-Modifying Enzymes

New Nomenclature for Chromatin-Modifying Enzymes

In the last ten years, the importance of chromatin modifications in many aspects of biology has become apparent. Several families of enzymes that modify histones have been identified, the majority of which are conserved throughout evolution. The enormous interest in this field has resulted in a very rapid rate of discovery of new enzymes, but this in turn has lead to a noncoherent nomenclature ...

Chromatin-modifying enzymes in transcription and cancer

In recent years, our view of how gene expression is controlled has changed dramatically. The discovery of enzymes that modify histones has revealed that transcription is an enzymically driven process. Such modifications can recruit specific proteins and mediate chromatin changes that affect transcription either positively or negatively. Important biological pathways leading to cell proliferatio...
