Organism

Synechocystis sp. (strain PCC 6803 / Kazusa)

Taxonomic identifier

1111708 [NCBI]

Taxonomic lineage

Bacteria › Cyanobacteria › Chroococcales › Synechocystis

Protein attributes

Sequence length	508 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Catalytic activity	Chorismate + L-glutamine = anthranilate + pyruvate + L-glutamate.
Pathway	Amino-acid biosynthesis; L-tryptophan biosynthesis; L-tryptophan from chorismate: step 1/5.
Subunit structure	Tetramer of two components I and two components II By similarity.
Miscellaneous	Component I catalyzes the formation of anthranilate using ammonia rather than glutamine, whereas component II provides glutamine amidotransferase activity.
Sequence similarities	Belongs to the anthranilate synthase component I family.
Sequence caution	The sequence AAA88627.1 differs from that shown. Reason: Frameshift at position 182.
