General Information
| General Information | Comment | Organism |
|---|---|---|
| physiological function | heterologous expression in the 4E-3 mutant strain of the model non-nitrogen-fixing cyanobacterium Synechocystis sp. PCC 6803, which lacks any psbA gene. The resultant strain cannot grow photoautotrophically. These Synechocystis 6803 cells are incapable of PSII-mediated oxygen evolution. This D1 isoform, sentinel D1, represents a class of D1 protein that, when incorporated in a PSII complex, ensures that PSII cannot mediate water oxidation, thus allowing oxygen-sensitive processes such as nitrogen fixation to occur in cyanobacterial cells | Crocosphaera subtropica ATCC 51142 |
