Guanine monphosphate synthetase

GMP synthetase, GMPS, GMP synthase
In the de novo synthesis of purine nucleotides, IMP is the branch point metabolite at which point the pathway diverges to the synthesis of either guanine or adenine nucleotides. In the guanine nucleotide pathway, there are 2 enzymes involved in converting IMP to GMP, namely IMP dehydrogenase (IMPD1), which catalyzes the oxidation of IMP to XMP, and GMP synthetase, which catalyzes the amination of XMP to GMP.

Papers on GMP synthetase
Pharmacological targeting of guanosine monophosphate synthase suppresses melanoma cell invasion and tumorigenicity.
Nikiforov et al., Buffalo, United States. In Cell Death Differ, Nov 2015
Here, we report that guanosine monophosphate synthase (GMPS), an enzyme required for the de novo biosynthesis of GMP, has a major role in invasion and tumorigenicity of cells derived from either BRAF(V600E) or NRAS(Q61R) human metastatic melanomas.
GMP synthase is essential for viability and infectivity of Trypanosoma brucei despite a redundant purine salvage pathway.
Phillips et al., Dallas, United States. In Mol Microbiol, Sep 2015
The purine salvage pathway is redundant and contains two routes to guanosine-5'-monophosphate (GMP) formation: conversion from xanthosine-5'-monophosphate (XMP) by GMP synthase (GMPS) or direct salvage of guanine by hypoxanthine-guanine phosphoribosyltransferase (HGPRT).
Deubiquitination of Ci/Gli by Usp7/HAUSP Regulates Hedgehog Signaling.
Zhang et al., Nanjing, China. In Dev Cell, Aug 2015
Furthermore, we find that Usp7 forms a complex with GMP-synthetase (GMPS) to promote Hh pathway activity.
Hydrogen-sulfide-mediated vasodilatory effect of nucleoside 5'-monophosphorothioates in perivascular adipose tissue.
Hałas et al., Lublin, Poland. In Can J Physiol Pharmacol, Jul 2015
We examined whether the sulfur-containing AMP and GMP analogs AMPS and GMPS can serve as the H2S donors in PVAT.
Crystal Structure of USP7 Ubiquitin-like Domains with an ICP0 Peptide Reveals a Novel Mechanism Used by Viral and Cellular Proteins to Target USP7.
Saridakis et al., Toronto, Canada. In Plos Pathog, Jun 2015
Several USP7 partners, including ICP0, GMPS, and UHRF1, interact through its C-terminal domain (CTD), which contains five ubiquitin-like (Ubl) structures.
Elevated level of the second messenger c-di-GMP in Comamonas testosteroni enhances biofilm formation and biofilm-based biodegradation of 3-chloroaniline.
Cao et al., Singapore, Singapore. In Appl Microbiol Biotechnol, Feb 2015
To elucidate the impacts of elevating c-di-GMP level on environmental bioprocesses, we constructed a Comamonas testosteroni strain constitutively expressing a c-di-GMP synthase YedQ from Escherichia coli and examined its capability in biofilm formation and biodegradation of 3-chloroaniline (3-CA).
Transmission of the PabI family of restriction DNA glycosylase genes: mobility and long-term inheritance.
Kobayashi et al., Tokyo, Japan. In Bmc Genomics, 2014
One R.PabI and M.PabI homolog gene pair is observed immediately after the GMP synthase gene in both Campylobacter and Helicobacter, representing orthologs beyond genera.

Wojtak et al., Lublin, Poland. In Pharmacol Res, 2014
Recently, it has been demonstrated that synthetic nucleotide analogs, adenosine- and guanosine 5'-monophosphorothioates (AMPS and GMPS) can be converted to H2S and AMP or GMP, respectively, by purified histidine triad nucleotide-binding (Hint) proteins.

On the other, the activation of USP7 is increased, when the UBL-activated state is stabilized by allosteric binding of GMP synthetase.

The use of nuclear imaging for cardiac resynchronization therapy.
Garcia et al., Atlanta, United States. In Curr Cardiol Rep, 2010
Phase analysis allows nuclear cardiology modalities, such as gated blood-pool imaging and gated myocardial perfusion single photon emission computed tomography (GMPS), to assess LV dyssynchrony.
Diversity and distribution of hemerythrin-like proteins in prokaryotes.
Ward et al., Edinburgh, United Kingdom. In Fems Microbiol Lett, 2008
Some of these are short proteins as in eukaryotes; others appear to consist of a hemerythrin domain fused to another domain, generally a putative signal transduction domain such as a methyl-accepting chemotaxis protein, a histidine kinase, or a GGDEF protein (cyclic di-GMP synthase).

Saier et al., San Diego, United States. In Febs J, 2007
The other two families [sensor histidine kinase (SHK) and kinase/phosphatase/synthetase/hydrolase (KPSH)] have a single 5 TMS unit preceded by an N-terminal TMS and followed by a hydrophilic sensor histidine kinase domain (the SHK family) or catalytic domains resembling sensor kinase, phosphatase, cyclic di-GMP synthetase and cyclic di-GMP hydrolase catalytic domains, as well as various noncatalytic domains (the KPSH family).
