Behavioral Genetics: Guanylyl Cyclase Prompts Worms to Party
When it comes to foraging, there are two types of worm in the world: those who enjoy a party, and those who prefer to dine alone. Two recent reports describe roles for guanylyl cyclase in the neuromolecular signaling systems that effect this natural behavioral dimorphism.
متن کاملGuanylyl cyclase sees the light
Cyclic guanosine monophosphate (cGMP) is a critical second messenger that regulates cardiovascular function and vision in humans. Two recent papers, including one in BMC Structural Biology, have revealed atomic structures of the enzymes that catalyze the synthesis of cGMP providing new clues about the molecular basis of substrate specificity and allosteric regulation in nucleotide cyclases.
متن کاملNO activation of guanylyl cyclase.
Nitric oxide (NO)-sensitive guanylyl-cyclase (GC) is the most important receptor for the signaling molecule NO. Activation of the enzyme is brought about by binding of NO to the prosthetic heme group. By monitoring NO-binding and catalytic activity simultaneously, we show that NO activates GC only if the reaction products of the enzyme are present. NO-binding in the absence of the products did ...
متن کاملNucleotidyl cyclase activity of soluble guanylyl cyclase in intact cells.
Soluble guanylyl cyclase (sGC) is activated by nitric oxide (NO) and generates the second messenger cyclic GMP (cGMP). Recently, purified sGC α1β1 has been shown to additionally generate the cyclic pyrimidine nucleotides cCMP and cUMP. However, since cyclic pyrimidine nucleotide formation occurred only the presence of Mn(2+) but not Mg(2+), the physiological relevance of these in vitro findings...
متن کاملNucleotidyl cyclase activity of recombinant soluble guanylyl cyclase
Background The ubiquitously expressed soluble guanylyl cyclase (sGC) converts guanosine 5'-triphosphate (GTP) to guanosine 3':5'-cyclic monophosphate (cGMP). The heterodimeric protein is activated by nitric oxide (NO). sGC plays a key role in the regulation of vascular tone and neurotransmission. Hence, sGC is an important target for the treatment of cardiovascular diseases e.g. pulmonary hyper...
