Sažetak
Gluthatione is an important antioxidant in plants and animals. It plays key roles in the activation of defense genes, redox buffering, sensing and detoxifying reactive oxygen species (ROS) and by participating in ROS-signaling pathways. Gluthatione can also be found in many bacteria where it represents the predominant intracellular thiol compound [1]. The protection of gluthatione against ROS is especially important for cyanobacteria that rely on photosynthesis in order to produce sufficient carbon for growth and cell metabolism. As high levels of ROS are commonly formed during photosynthesis and have the potential to destroy cellular components, gluthatione and relatd derivates are important for cell survival. Even though the roles of gluthatione in bacteria are well investigated its subcellular distribution is still unclear as methods for its detection within cyanobacteria are not available.
