title: Mechanism of the adenylate cyclase reaction. Stereochemistry of the reaction catalyzed by the enzyme from Brevibacterium liquefaciens.
abstract: Adenylate cyclase from Brevibacterium liquefaciens (ATCC 14929) catalyzes the formation of the RP-diastereomer of adenosine 3':5'-cyclic monophosphorothioate from the SP-diastereomer of adenosine-5'-(1-thiotriphosphate). The reaction catalyzed by this adenylate cyclase proceeds with inversion of configuration at phosphorus, indicating that the cyclization reaction is direct and does not involve formation of an adenylated enzyme intermediate.
