Adenylate and cyclase

Adenylate and is
Adenylate kinase () ( also known as ADK or myokinase ) is a phosphotransferase enzyme that catalyzes the interconversion of adenine nucleotides, and plays an important role in cellular energy homeostasis.
Adenylate Kinase is a signal transducing protein ; thus, the balance between conformations regulates protein activity.
Adenylate kinase deficiency in the erythrocyte is associated with hemolytic anemia.
The reaction that Adenylate Cyclase catalyzes is the conversion of ATP to 3 ', 5 '- cyclic AMP.

Adenylate and by
Adenylate cyclases are often activated or inhibited by G proteins, which are coupled to membrane receptors and thus can respond to hormonal or other stimuli.

cyclase and is
The i stands for inhibition of the adenylate cyclase ; another effector molecule for this protein family is phospholipase C. Also, G < sub > t </ sub > and G < sub > g </ sub > proteins are summarized under this label due to sequence homologies.
An example is adenylate cyclase, which produces the second messenger cyclic AMP.
This is accomplished by direct stimulation of the membrane-associated enzyme adenylate cyclase.
It is synthesised from arginine and oxygen by the NO synthase and works through activation of soluble guanylyl cyclase, which when activated produces another second messenger, cGMP.
This is mediated via the A1 receptor, inhibiting adenylyl cyclase, reducing cAMP and so causing cell hyperpolarization by increasing outward K + flux.
Confirmation of the diagnosis is with tests that evaluate the degree of inhibition of adenylyl cyclase by ADP.
The latter mastergene is responsible for the expression of intestinal markers such as Guanylate cyclase 2C

The calcitonin receptor, found on osteoclasts, and in kidney and regions of the brain, is a G protein-coupled receptor, which is coupled by G < sub > s </ sub > to adenylate cyclase and thereby to the generation of cAMP in target cells.
The cAMP level is related not to intracellular glucose concentration but to the rate of glucose transport, which influences the activity of adenylate cyclase.
Guanylate cyclase (, also known as guanylyl cyclase, guanyl cyclase or GC ) is a lyase enzyme.
Guanylate cyclase is part of the G protein ( does not use the G protein cascade in vertebrates ) signaling cascade that is activated by low intracellular calcium levels and inhibited by high intracellular calcium levels.
Guanylyl cyclase is found in the retina ( RETGC ) and modulates phototransduction in rods and cones.
Soluble guanylate cyclase contains a molecule of heme, and is primarily activated by the binding of nitric oxide ( NO ) to that heme ).

Upon stimulation, adenylate cyclase is activated within the parietal cells.
Soluble guanylate cyclase ( sGC ) is the intracellular receptor for NO.

cyclase and regulated
One of the most important of the regulated toxins is adenylate cyclase toxin, which aids in the evasion of innate immunity.

cyclase and by
The outside signal ( in this case, adrenaline ) binds to a receptor, which transmits a signal to the G protein, which transmits a signal to adenylate cyclase, which transmits a signal by converting adenosine triphosphate to cyclic adenosine monophosphate ( cAMP ).
Following activation of adenylate cyclase, the resulting cAMP acts as a second messenger by interacting with and regulating other proteins such as protein kinase A and cyclic nucleotide-gated ion channels.
They are coupled to G < sub > s </ sub > and increase the cellular concentrations of cAMP by the activation of the enzyme adenylate cyclase.
They are coupled to G < sub > i </ sub >/ G < sub > o </ sub > and decrease the cellular concentrations of cAMP by inhibition of adenylate cyclase.
