Soluble guanylate cyclase

Poulos, Thomas L·2006·Current Opinion in Structural Biology

Abstract

Soluble guanylate cyclase (sGC) is a mammalian nitric oxide (NO) sensor. When NO binds to the sGC heme, its GTP cyclase activity markedly increases, thus generating cyclic GMP, which serves to regulate several cell signaling functions. A good deal is known about the kinetics and equilibrium of binding of NO to sGC, leading to a proposed multistep mechanism of sGC activation that involves at least two NO-binding sites. The crystal structure of a member of a recently discovered family of prokaryotic sGC homologues has provided important insights into structure-function relationships within the sGC family of proteins.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
