Eucaryotic microorganism

The general outline of the pathways of amino acid biosynthesis is shown in Figure 2.1. It should be stressed that the detailed enzymology of these pathways is far better understood in bacteria and some eucaryotic microorganisms than in higher plants indeed, in most plant species, information on the relevant enzymology is fragmentary. As will be seen later. 

The terminal oligosaccharide structures (glycans) in glycoconjugates which are associated with the eucaryotic cell represent specific contact and recognition sites for other cells, microorganisms, viruses, proteins, hormones and toxins. 

In recent years, the overview of the exopolyphosphatases classification and function has been renewed a great deal. A significant diversity of exopolyphosphatases in microorganisms and sufficient differences in their structure and properties in procaryotes and eucaryotes have come to light. 

A third type of structure that does not belong to the previous classifications is the virus. Although viruses are not strictly organisms, microorganisms, in general, may be classified as eucaryotic protists, procaryotic protists, and viruses. 

Nitroreductases , which catalyze the reduction of nitro groups to amino groups, are ubiquitous in microorganisms as well as in higher organisms. In eucaryotes, nitro-reducing activity very often is an unspecific side activity of another enzyme. In rat liver, for example, nitro reduction is mediated by various enzymes of normal liver metabolism.
