Prokaryotes classification

First, the taxonomic classification of the TrEMBL entry must be within the known taxonomic range of the PROSITE pattern. For instance, a match of an a priori prokaryotic pattern against a human protein is regarded as false positive and filtered out.

Micro-organisms, the major form of organisms for biotechnology, can be split into several groups based upon biochemical activity and structure. The basic classification of the protist is shown in Fig. 5.3. There are two major types, the Prokaryotes and the Eukaryotes and Table 5.4 illustrates the main distinguishing features between the two cell types. The major differences are reviewed in the following sections. 

We have many times emphasized that all life has very similar chemistry. Indeed, in terms of biochemistry there is little need for the classifications of mammals, plants, and so on. There is only one important division—into prokaryotes and eukaryotes. Prokaryotes, which include bacteria, evolved first and have simple cells with no nucleus. Eukaryotes, which include plants, mammals, and all... 

Monera Prokaryotic kingdom that includes (in the most widely accepted classification system) archaebacteria, eubacteria, and cyanobacteria. Members of this kingdom were among the first forms of life over 3.5 billion years ago. 

Currently, the most widely accepted system of classification of organisms is the five-kingdom system (Table 3-3) of Whittaker (1969). Prokaryotic organisms are placed in the Kingdom Monera, which includes the bacteria and cyanobacteria whose...
