General Information

General Information	Comment	Organism
physiological function	disruption of subunit PntA results in phenotypic growth defects observed under low light intensities in the presence of glucose. Under autotrophic conditions the disruption mutant does not differ from the wild-type strain. The phenotypic defects of the mutant are accompanied by significant malfunction and damage of the photosynthetic machinery	Synechocystis sp. PCC 6803
