Diguanylate cyclase DosC

Gene

dosC

Organism
Shigella boydii serotype 4 (strain Sb227)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Globin-coupled heme-based oxygen sensor protein displaying diguanylate cyclase (DGC) activity in response to oxygen availability. Thus, catalyzes the synthesis of cyclic diguanylate (c-di-GMP) via the condensation of 2 GTP molecules. Cyclic-di-GMP is a second messenger which controls cell surface-associated traits in bacteria (By similarity).By similarity

Catalytic activityi

2 GTP = 2 diphosphate + cyclic di-3',5'-guanylate.

Cofactori

Protein has several cofactor binding sites:
  • hemeBy similarityNote: Binds 1 heme group per subunit.By similarity
  • Mg2+By similarityNote: Binds 1 Mg2+ ion per subunit.By similarity

Pathwayi: 3',5'-cyclic di-GMP biosynthesis

This protein is involved in the pathway 3',5'-cyclic di-GMP biosynthesis, which is part of Purine metabolism.
View all proteins of this organism that are known to be involved in the pathway 3',5'-cyclic di-GMP biosynthesis and in Purine metabolism.
