Organisms metabolic classification

Metabolic Classification of Organisms According to Their Carbon and Energy Requirements ... 

These chemicals made by the majority of organisms, hence considered essential for life, were categorised by Kossel as primary metabolism but as explained in Chapter 9. Kossel s classification was seriously flawed. 

Each PIR entry consists of Entry (entry ID), Title, Alternate names, Organism, Date, Accession (accession number), Reference, Function (description of protein function), Comment (e.g., enzyme specificity and reaction, etc.), Classification (superfamily), Keywords (e.g., dimer, alcohol metabolism, metalloprotein, etc.), Feature (lists of sequence positions for disulfide bonds, active site and binding site amino acid residues, etc.), Summary (number of amino acids and the molecular weight), and Sequence (in PIR format, Chapter 4). In addition, links to PDB, KEGG, BRENDA, WIT, alignments, and iProClass are provided. 

Table 2 Classification terms for nticrobial metabolism. Each term is composed of modifiers for the source of energy (chentical versus fight), the source of electrons (inorganic versus organic), and the source of carhon (inorganic versus organic). The modifiers are linked in the order energy-electrons-carhon. Metabolisms for which organic carhon is hoth the carhon and energy source are abbreviated as heterotrophy. ...
