Cyclic adenosine monophosphate biosynthesis

Traub O, Look J, Paul D, Willecke K Cyclic adenosine monophosphate stimulates biosynthesis and phosphorylation of the 26 kDa gap junction protein in cultured mouse hepatocytes. Eur J Cell Biol 1987 43 48-54. 

Still about saponin 1,87, isolated from A. membranaceus, Zhang et al. [317] report that this substance induces the accumulation of cyclic adenosine monophosphate (cAMP) and cyclic guanidine monophosphate (cGMP) in rabbit plasma and affects DNA biosynthesis in partially... 

It is widely known that cyclic nucleotides are involved in fundamental processes, which include those related to platelet aggregation. In this way, the inhibition of the enzyme phosphodiesterase could be one such mechanism through its effect on cAMP (Cyclic Adenosin Monophosphate) and cGMP (Cyclic Guanosine Monophosphate) [117], Another mechanism might involve inhibition of cycloxygenase, with a consequent depression of thromboxane A2 biosynthesis [115] as well as some influence on the inhibition of the intracellular mobilization of Ca2+ flux and its influx across the plasma membrane, as happens with genistein [118]. 

Luteinizing hormone binds to its receptor on the surface of the Leydig cells to initiate testosterone biosynthesis. As in other endocrine cells, the binding of gonadotropin activates the Gs signal transduction pathway, increasing intracellular cyclic adenosine monophosphate (cAMP) levels via activation of adenylate cyclase. One of the processes influenced by elevated cAMP levels is the... 

Biosynthesis of TRH occurs in a wide area of the hypothalamus and appears to be under the control of a nonribosomal (soluble) enzyme system, TRH synthetase (R5), which is activated by norepinephrine (G15). TRH is stored in the median eminence, from which is secreted into the hypophysial venous portal system to be transported to the anterior pituitary gland (R2). There it is specifically bound to membrane receptors (G13, W3) and activates adenyl cyclase, leading to increased production of cyclic adenosine monophosphate (K1). 

The phosphate group can also form cyclic esters and this is observed in the case of the biosynthesis of cyclic adenosine monophosphate (cAMP) (Fig. 5.53), which is an important intracellular messenger formed within cells, for... 

Cyclic AMP Stimulation or inhibition of the biosynthesis of the second messenger cyclic adenosine-S jS -monophosphate occurs through the activation of Gs or G protein-coupled neurotransmitter receptors, respectively. 

The effect of light in combination with exogenous precursors on amaranthin biosynthesis has been studied, as has the effect of cyclic 3, 5 -adenosine monophosphate. ...
