Nucleotidyl 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...
متن کاملRegulation of soluble guanylyl cyclase by phosphorylation
Results In vitro kinase assays revealed that the α1, but not the β1, subunit of sGC is a PKG substrate and that the phosphorylation site is located within the first 360 residues of the α1. A constitutively active form of PKG stimulated incorporation of 32P into the α1 subunit in vivo. In addition, PKG could be detected in sGC immunoprecipitates, suggesting that the two proteins interact in cell...
متن کاملSoluble guanylyl cyclase activation promotes angiogenesis.
Soluble guanylyl cyclase (sGC) is a cGMP-generating enzyme carrying a heme prosthetic group that functions as a nitric oxide (NO) sensor. sGC is present in most cells types, including the vascular endothelium, where its biological functions remain largely unexplored. Herein, we have investigated the role of sGC in angiogenesis and angiogenesis-related properties of endothelial cells (EC). Initi...
متن کاملBiochemistry and pharmacology of novel anthranilic acid derivatives activating heme-oxidized soluble guanylyl cyclase.
The heme-enzyme soluble guanylyl cyclase (sGC) is an ubiquitous NO receptor, which mediates NO downstream signaling by the generation of cGMP. We studied the mechanism of action of the anthranilic acid derivatives 5-chloro-2-(5-chloro-thiophene-2-sulfonylamino-N-(4-(morpholine-4-sulfonyl)-phenyl)-benzamide sodium salt (HMR1766) (proposed international nonproprietary name, ataciguat sodium) and ...
