Nucleotidyl cyclase activity of soluble guanylyl cyclase α1β1.
Biochemistry, 2012Soluble guanylyl cyclase (sGC) regulates several important physiological processes by converting GTP into the second-messenger cGMP. sGC has several structural and functional properties in common with adenylyl cyclases (ACs).

Adenylyl cyclase amino acid sequence: possible channel- or transporter-like structure.
Science, 1989Complementary DNA's that encode an adenylyl cyclase were isolated from a bovine brain library. Most of the deduced amino acid sequence of 1134 residues is divisible into two alternating sets of hydrophobic and hydrophilic domains.

Publisher Summary This chapter describes the enzyme (adenylyl cyclase) that effect the synthesis of Adenosine 3’,5’-cyclic monophosphate (cAMP) in various bacterial species. The content will rather reflect current major interests. The adenylyl cyclase from Escherichia coli has been a major subject of research interest ever since it was identified as ...

This study demonstrates that a tetraprenyl-β-curcumene cyclase, which was originally identified as a sesquarterpene cyclase that converts a head-to-tail type of monocycle to a pentacycle, also cyclizes a tail-to-tail type of linear squalene into a bicyclic triterpenol, 8α-hydroxypolypoda-13,17,21-triene. The 8α-hydroxypolypoda-13,17,21-triene was found

Guanyl cyclase of Bacilluslicheniformis
Biochemical and Biophysical Research Communications, 1972Abstract Guanyl cyclase activity was detected in extracts of Bacillus licheniformis strain A-5. The enzyme is associated with the 105,000 × g particulate fraction of the extract, requires Mn++ for full activity, has a pH optimum of 8.5, and has an apparent Km for GTP of 5mM.

Signal transduction via receptors that couple to guanine nucleotide binding proteins (G proteins) is pervasive throughout eukaryotic and prokaryotic biology. In humans, there are thought to be thousands of different G protein–coupled receptors (GPCRs), which carry out an amazingly diverse array of signaling, such as odorant detection, phototransduction,

Current Opinion in Structural Biology, 2006
Soluble guanylate cyclase (sGC) is a mammalian nitric oxide (NO) sensor. When NO binds to the sGC heme, its GTP cyclase activity markedly increases, thus generating cyclic GMP, which serves to regulate several cell signaling functions. A good deal is known about the kinetics and equilibrium of binding of NO to sGC, leading to a proposed multistep ...
