Class III nucleotide cyclases in bacteria and archaebacteria: lineage-specific expansion of adenylyl cyclases and a dearth of guanylyl cyclases [PDF]
The Class III nucleotide cyclases are found in bacteria, eukaryotes and archaebacteria. Our survey of the bacterial and archaebacterial genome and plasmid sequences identified 193 Class III cyclase genes in only 29 species, of which we predict the ...

Rhodopsin-cyclases for photocontrol of cGMP/cAMP and 2.3 Å structure of the adenylyl cyclase domain
Cyclic AMP and cGMP orchestrate a variety of cellular responses. Here, authors characterize the cGMP producing rhodopsin-guanylyl cyclase from C. anguillulae and derived adenylyl cyclase by a biochemical and structural approach which demonstrates the ...

Functional Crypto-Adenylate Cyclases Operate in Complex Plant Proteins
Adenylyl cyclases (ACs) and their catalytic product cAMP are regulatory components of many plant responses. Here, we show that an amino acid search motif based on annotated adenylate cyclases (ACs) identifies 12 unique Arabidopsis thaliana candidate ACs,

Background The Ca2+/calmodulin-stimulated adenylyl cyclase (AC) isoforms AC1 and AC8, couple NMDA receptor activation to cAMP signaling pathways in neurons and are important for development, learning and memory, drug addiction and persistent pain.

In the early 1960s, Earl Sutherland and his colleagues performed a series of experiments that led to the understanding that the positive inotropic effects of β-adrenergic agonists were mediated by the activation of the enzyme adenylyl cyclase (AC) and the subsequent production of cyclic adenosine monophosphate (cAMP).1 By measuring tissue cAMP levels ...

Cyclic adenosine monophosphate (cAMP) is a key cellular second messenger. Adenylyl cyclase converts emissive isomorphic nucleoside triphosphates into fluorescent cAMPs. cthAMP displays unusually high brightness compared to thATP, its precursor, enabling real‐time monitoring of enzymatic reactions.

Cyclic nucleotide binding and structural changes in the isolated GAF domain of Anabaena adenylyl cyclase, CyaB2 [PDF]
GAF domains are a large family of regulatory domains, and a subset are found associated with enzymes involved in cyclic nucleotide (cNMP) metabolism such as adenylyl cyclases and phosphodiesterases.

P-Rex1 is a guanine-nucleotide exchange factor (GEF) that activates Rac-type small G proteins in response to the stimulation of a range of receptors, particularly G protein-coupled receptors (GPCRs), to control cytoskeletal dynamics and other Rac ...

Adenylyl cyclase alpha and cAMP signaling mediate Plasmodium sporozoite apical regulated exocytosis and hepatocyte infection. [PDF]
Malaria starts with the infection of the liver of the host by Plasmodium sporozoites, the parasite form transmitted by infected mosquitoes. Sporozoites migrate through several hepatocytes by breaching their plasma membranes before finally infecting one ...

Identification and Localization of the Cyclic Nucleotide Phosphodiesterase 10A in Bovine Testis and Mature Spermatozoa. [PDF]
In mammals, adenosine 3', 5'-cyclic monophosphate (cAMP) is known to play highly important roles in sperm motility and acrosomal exocytosis. It is known to act through protein phosphorylation via PRKA and through the activation of guanine nucleotide ...
