The COOH-terminal octapeptide of cholecystokinin (CCK-OP) and carbamylcholine each increased calcium outflux, cellular cyclic GMP and amylase secretion in dispersed guinea pig pancreatic acinar cells. Following addition of CCK-OP or carbamylcholine, cellular cyclic GMP increased as early as 15 s, became maximal after 1 to 2 min, and then decreased steadily during the subsequent incubation. For ...

Genetically modified plants (GMPs) may soon be cultivated commercially in several member countries of the European Union (EU). According to EU Directive 2001/18/EC, post-market monitoring (PMM) for commercial GMP cultivation must be implemented, in order to detect and prevent adverse effects on human health and the environment. However, no general PMM strategies for GMP cultivation have been es...

Catecholamines increased guanosine 3':5'-monophosphate (cyclic GMP) accumulation by isolated rat liver cells. The increases in cyclic GMP due to 1.5 muM epinephrine, isoproterenol, or phenylephrine were blocked by phenoxybenzamine but not by propranolol. The possibility that cyclic GMP is involved in the glycogenolytic action of catecholamines seems unlikely since cyclic GMP accumulation is als...

Pseudomonas aeruginosa is a Gram-negative, opportunistic pathogen that utilizes polar type IV pili (T4P) for twitching motility and adhesion in the environment and during infection. Pilus assembly requires FimX, a GGDEF/EAL domain protein that binds and hydrolyzes cyclic di-GMP (c-di-GMP). Bacteria lacking FimX are deficient in twitching motility and microcolony formation. We carried out an ext...

Lasserre's moment-SOS hierarchy consists of approximating instances the generalized moment problem (GMP) with relaxations and sums-of-squares (SOS) strenghtenings that boil down to convex semidefinite programming (SDP) problems. Due generality initial GMP, applications this technology are countless, one can cite among them polynomial optimization (POP), optimal control (OCP), volume computation...

The second messenger cyclic diguanylate (c-di-GMP) controls diverse cellular processes among bacteria. Diguanylate cyclases synthesize c-di-GMP, whereas it is degraded by c-di-GMP-specific phosphodiesterases (PDEs). Nearly 80% of these PDEs are predicted to depend on the catalytic function of glutamate-alanine-leucine (EAL) domains, which hydrolyze a single phosphodiester group in c-di-GMP to p...

We used cultured rat lung fibroblasts to evaluate the role of particulate and soluble guanylate cyclase in the atrial natriuretic factor (ANF)-induced stimulation of cyclic GMP. ANF receptors were identified by binding of 125I-ANF to confluent cells at 37 degrees C. Specific ANF binding was rapid and saturable with increasing concentrations of ANF. The equilibrium dissociation constant (KD) was...

The universal and pleiotropic cyclic dinucleotide second messenger c-di-GMP is most prominently known to inversely regulate planktonic and sessile lifestyles of Gram-negative species. In the Gram-positive model organism Bacillus subtilis, intracellular c-di-GMP levels are modulated by a concise set of three diguanylate cylases (DgcK, DgcP, DgcW) and one phosphodiesterase (PdeH). Two recent stud...

Bdellovibrio bacteriovorus is a Delta-proteobacterium that oscillates between free-living growth and predation on Gram-negative bacteria including important pathogens of man, animals and plants. After entering the prey periplasm, killing the prey and replicating inside the prey bdelloplast, several motile B. bacteriovorus progeny cells emerge. The B. bacteriovorus HD100 genome encodes numerous ...
