To tell:
How much nitrogen is needed to produce amino acids through amination?
Introduction:
Some microorganisms (fungi, pathogenic bacteria, and food-spoilage bacteria) catabolize proteins as a vital source of metabolites and energy. Maximum cells catabolize amino acids and proteins, only when there is a lack of carbon sources like fat and glucose. In general, proteins are macromolecules that pass through cytoplasmic membranes. Thus, prokaryotic organisms carry out protein catabolism (outside the cell) through discharging an enzyme protease, which splits the proteins into amino acids. Later, the amino acids are shifted to the cell, and again get split into amino groups, by a process which is termed as deamination. This modified molecule reaches the Krebs cycle, where it can be recycled to form other amino groups or be defecated as ammonia or nitrogenous wastes.
