Cyanobacterium UCYN-A

UCYN-A cyanobacteria
Scientific classification
Kingdom:	Bacteria
Phylum:	Cyanobacteria
Order:	Chroococcales
Species:	cyanobacterium UCYN-A

UCYN-A cyanobacteria are species of nitrogen-fixing marine cyanobacteria that lack the oxygen producing photosystem II complex of the photosynthetic apparatus, the enzymes of the Calvin and tricarboxylic acid cycles, as well as several enzymes involved in amino acid synthesis, indicating a novel metabolism.^[1][2]
