“…Nevertheless, it may be significant that the only amino acid to show significant changes during the period of nitrogen fixation was arginine, which is a major component of cyanophycin. This polymer has been suggested t o have a role in nitrogen-storage in some cyanobacteria [8], though its intracellular concentration, unlike that of arginine itself, showed little variation during growth of Gloeothece under alternating light and darkness [9]. DNA topoisomerases are enzymes that modify the topology (for example, the degree of supercoiling) of the DNA chromosome.…”
