Nucleotidyl 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...
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 Particulate Guanylyl Cyclase A: Comparison with Particulate Guanylyl Cyclases E and F, Soluble Guanylyl Cyclase and Bacterial Adenylyl Cyclases Cyaa and Edema Factor
Guanylyl cyclases (GCs) regulate many physiological processes by catalyzing the synthesis of the second messenger cGMP. The GC family consists of seven particulate GCs (pGCs) and a nitric oxide-activated soluble GC (sGC). Rat sGC α1β1 possesses much broader substrate specificity than previously assumed. Moreover, the exotoxins CyaA from Bordetella pertussis and edema factor (EF) from Bacillus a...
متن کاملHuman recombinant soluble guanylyl cyclase: expression, purification, and regulation.
The alpha1- and beta1-subunits of human soluble guanylate cyclase (sGC) were coexpressed in the Sf9 cells/baculovirus system. In addition to the native enzyme, constructs with hexahistidine tag at the amino and carboxyl termini of each subunit were coexpressed. This permitted the rapid and efficient purification of active recombinant enzyme on a nickel-affinity column. The enzyme has one heme p...
متن کاملCardiovascular effects of modulators of soluble guanylyl cyclase activity.
Soluble guanylyl cyclase (sGC) is one of the key enzymes of the nitric-oxide (NO)/cyclic 3',5'-guanosine monophosphate (cGMP) pathway. Located in virtually all mammalian cells, it controls the vessel tone, smooth muscle cell growth, platelet aggregation, and leukocyte adhesion. In vivo sGC activity is mainly regulated by NO which in turn is released from L-arginine by nitric oxide synthases. On...
