Sažetak
Nitrogen in soil occurs in several organic and inorganic forms. Proteins, nucleic acids, and other heterocyclic N-compounds, such as peptidoglycan and chitin, are the major sources of nitrogen. Degradation of proteins occurs through intra- and extracellular proteolytic enzymes. Whereas intracellular proteases are more related to the regulation of metabolic processes in cells, hydrolysis of large polypeptidic compounds through the extracellular enzymes is of prime importance for the global N-turnover, thus resulting in the formation of low-molecular-weight products that could be transported across the cell membrane.
