I was unable to reveal such gene as mys B in PCC 6803 genome while the authors of this article

"Protective effects of mycosporine-like amino acids of Synechocystis sp. PCC 6803 and their partial characterization"

mentioned that 6803 produces such compounds as mycosporine-tau and dehydroxylusujirene. Unfortunately, this article has no info about molecular base of these compounds biosynthesis. This is why I would like to ask the colleagues studying MAAs biosynthesis to recommend me publications which may help me to learn anything about molecular mechanisms of this process.

Thank you all in advance.
