Study of excess manganese stress response highlights the central role of manganese exporter Mnx for holding manganese homeostasis in the cyanobacterium sp. PCC 6803.

Cellular levels of the essential micronutrient manganese (Mn) need to be carefully balanced within narrow borders. In cyanobacteria, a sufficient Mn supply is critical for ensuring the function of the oxygen-evolving complex as the central part of the photosynthetic machinery. However, Mn accumulation is fatal for the cells.

Circularly assembled genome sequences of sp. strain MM231 and MM232, isolated from a pond at Bielefeld University campus.

Photosynthetic organisms often interact with heterotrophic microbes. We here report the complete genome sequences of the bacterial strains sp. MM231 and MM232.
