Phytic acid, a phosphorylated derivative of myo-inositol, functions as the major storage form of phosphorus in plant seeds. Myo-inositol phosphates, including phytic acid, play diverse roles in plants as signal transduction molecules, osmoprotectants, and cell wall constituents. D-myo-inositol-3-phosphate synthase (MIPS EC 5.5.1.4) catalyzes the first step in de novo synthesis of myo-inositol. ...

The multifunctional position supplied by myo-inositol is emerging as a central feature in plant biochemistry and physiology. In this critique, attention is drawn to metabolic aspects and current assessment is made of manifold ways in which myo-inositol and its metabolic products impact growth and development. The fact that a unique enzyme, common to all eukaryotic organisms where such assessmen...

Cell wall polysaccharides of the hypocotyl and roots in germinating beans (Phaseolus vulgaris L.) were selectively labeled in arabinosyl, xylosyl, and galacturonosyl residues by per-C-deuterated myo-inositol, which was introduced through 72 hours of imbibition. Glucuronate residues remained unlabeled. Selected ion gas chromatography-mass spectrometry analysis revealed that deuterium was not red...

D-glucaric acid has been explored for a myriad of potential uses, including biopolymer production and cancer treatment. A biosynthetic route to produce D-glucaric acid from glucose has been constructed in Escherichia coli (Moon et al., 2009b), and analysis of the pathway revealed myo-inositol oxygenase (MIOX) to be the least active enzyme. To increase pathway productivity, we explored protein f...

BACKGROUND AND OBJECTIVES Inositol is a component of the vitamin B complex. Myo-inositol (MYO) is the most biologically important form in nature. It is involved in several systemic processes and in mechanisms of signal transduction in the plasma membrane as precursor of second messengers. On the male reproductive function, MYO appears to regulate seminal plasma osmolarity and volume; the expres...

scyllo-Inositol is the all equatorial stereoisomer of myo-inositol. All possible 12 regioisomers of scyllo-inositol phosphate were synthesized for the first time via a scyllo-inositol benzoate intermediate, which was derived from a myo-inositol derivative. The stereoinversion of myo-inositol into scyllo-inositol was accomplished by Mitsunobu reaction of the vicinal cis-diol. The requisite inter...

We have experimentally and computationally defined a set of genes that form a conserved metabolic module in the alpha-proteobacterium Caulobacter crescentus and used this module to illustrate a schema for the propagation of pathway-level annotation across bacterial genera. Applying comprehensive forward and reverse genetic methods and genome-wide transcriptional analysis, we (1) confirmed the p...

OBJECTIVE In patients with acute myocardial infarction (AMI), estimation of infarct size from the early markers, fatty acid-binding protein (FABP) and myoglobin (MYO), usually assumes average (fixed) rate constants (FCR) for protein clearance from plasma. However, individual variation in FCR is large. Renal dysfunction causes slower clearance of FABP and MYO from plasma and, hence, overestimati...

Inositol is a physiological compound belonging to the sugar family. The two inositol stereoisomers, myo-inositol and D-chiroinositol are the two main stereisomers present in our body. Myo-inositol is the precursor of inositol triphosphate, a second messenger regulating many hormones such as TSH, FSH and insulin. D-chiroinositol is synthetized by an insulin dependent epimerase that converts myo-...
