We report a slr0280-deleted mutant of Synechocystis, whose growth is moderately defective in the presence of glucose.
Slr0280 is characterized as a novel periplasmic protein.
DUF2233 domain of Slr0280 interacts with the several proteins that are relevant to carbohydrate metabolism.
Slr0280 has a positive regulation on sugar catabolism and Calvin cycle.
