Polyamine biosynthetic enzymes as drug targets in parasitic protozoa.

abstract：:It has long been reported that Mycobacterium tuberculosis is capable of synthesizing the α-glucan glycogen. However, what makes this bacterium stand out is that it coats itself in a capsule that mainly consists of a glycogen-like α-glucan. This polymer helps the pathogen evade immune responses. In 2010, the biosynthes...
