Isolation and characterization of the gene coding for the amidinotransferase involved in the biosynthesis of phaseolotoxin in Pseudomonas syringae pv. phaseolicola. (1/58)

Pseudomonas syringae pv. phaseolicola is the causal agent of the "halo blight" disease of beans. A key component in the development of the disease is a nonhost-specific toxin, Ndelta-(N'-sulphodiaminophosphinyl)-ornithyl-alanyl-homoarginine, known as phaseolotoxin. The homoarginine residue in this molecule has been suggested to be the product of L-arginine:lysine amidinotransferase activity, previously detected in extracts of P. syringae pv. phaseolicola grown under conditions of phaseolotoxin production. We report the isolation and characterization of an amidinotransferase gene (amtA) from P. syringae pv. phaseolicola coding for a polypeptide of 362 residues (41.36 kDa) and showing approximately 40% sequence similarity to L-arginine:inosamine-phosphate amidinotransferase from three species of Streptomyces spp. and 50.4% with an L-arginine:glycine amidinotransferase from human mitochondria. The cysteine, histidine, and aspartic acid residues involved in substrate binding are conserved. Furthermore, expression of the amtA and argK genes and phaseolotoxin production occurs at 18 degrees C but not at 28 degrees C. An amidinotransferase insertion mutant was obtained that lost the capacity to synthesize homoarginine and phaseolotoxin. These results show that the amtA gene isolated is responsible for the amidinotransferase activity detected previously and that phaseolotoxin production depends upon the activity of this gene.  (+info)

Arginine:glycine amidinotransferase deficiency: the third inborn error of creatine metabolism in humans. (2/58)

Arginine:glycine amidinotransferase (AGAT) catalyzes the first step of creatine synthesis, resulting in the formation of guanidinoacetate, which is a substrate for creatine formation. In two female siblings with mental retardation who had brain creatine deficiency that was reversible by means of oral creatine supplementation and had low urinary guanidinoacetate concentrations, AGAT deficiency was identified as a new genetic defect in creatine metabolism. A homozygous G-A transition at nucleotide position 9297, converting a tryptophan codon (TGG) to a stop codon (TAG) at residue 149 (T149X), resulted in undetectable cDNA, as investigated by reverse-transcription PCR, as well as in undetectable AGAT activity, as investigated radiochemically in cultivated skin fibroblasts and in virus-transformed lymphoblasts of the patients. The parents were heterozygous for the mutant allele, with intermediate residual AGAT activities. Recognition and treatment with oral creatine supplements may prevent neurological sequelae in affected patients.  (+info)

Methylation demand and homocysteine metabolism: effects of dietary provision of creatine and guanidinoacetate. (3/58)

S-adenosylmethionine, formed by the adenylation of methionine via S-adenosylmethionine synthase, is the methyl donor in virtually all known biological methylations. These methylation reactions produce a methylated substrate and S-adenosylhomocysteine, which is subsequently metabolized to homocysteine. The methylation of guanidinoacetate to form creatine consumes more methyl groups than all other methylation reactions combined. Therefore, we examined the effects of increased or decreased methyl demand by these physiological substrates on plasma homocysteine by feeding rats guanidinoacetate- or creatine-supplemented diets for 2 wk. Plasma homocysteine was significantly increased (~50%) in rats maintained on guanidinoacetate-supplemented diets, whereas rats maintained on creatine-supplemented diets exhibited a significantly lower (~25%) plasma homocysteine level. Plasma creatine and muscle total creatine were significantly increased in rats fed the creatine-supplemented or guanidinoacetate-supplemented diets. The activity of kidney L-arginine:glycine amidinotransferase, the enzyme catalyzing the synthesis of guanidinoacetate, was significantly decreased in both supplementation groups. To examine the role of the liver in mediating these changes in plasma homocysteine, isolated rat hepatocytes were incubated with methionine in the presence and absence of guanidinoacetate and creatine, and homocysteine export was measured. Homocysteine export was significantly increased in the presence of guanidinoacetate. Creatine, however, was without effect. These results suggest that homocysteine metabolism is sensitive to methylation demand imposed by physiological substrates.  (+info)

On the control of arginine metabolism in chicken kidney and liver. (4/58)

Arginases have been found to be located on the external side of the inner mitochondrial membrane of chicken kidney and liver. Transamidinase has been detected within the liver mitochondrial matrix space. Arginases and transamidinase act upon two different intracellular arginine pools. Penetration of arginine into the matrix space occurs only in respring mitochondria and in the presence of anions such as acetate and phosphate; D-arginine, L-ornithine, D-'ornithine and L-lysine penetrate with the same modalities. L-Histidine penetrates only kidney mitochondria. Because of transamidinase compartmentation, the rate of creatine synthesis is influenced by the rate of penetration of arginine into the mitochondria.  (+info)

Guanidinoacetate and creatine plus creatinine assessment in physiologic fluids: an effective diagnostic tool for the biochemical diagnosis of arginine:glycine amidinotransferase and guanidinoacetate methyltransferase deficiencies. (5/58)

BACKGROUND: Disorders of creatine metabolism arise from genetic alterations of arginine:glycine amidinotransferase (AGAT), guanidinoacetate methyltransferase (GAMT), and the creatine transporter. We developed a strategy for the detection of AGAT and GAMT defects by measurement of guanidinoacetate (GAA) and creatine plus creatinine (Cr+Crn) in biological fluids. METHODS: Three patients with AGAT deficiency from the same pedigree and their eight relatives, as well as a patient affected by a GAMT defect and his parents were analyzed by a new HPLC procedure in comparison with 90 controls. The method, which uses precolumn derivatization with benzoin, separation with a reversed-phase column, and fluorescence detection, has shown good precision and sensitivity and requires minimal sample handling. RESULTS: In the three AGAT patients, plasma GAA was 0.01-0.04 micro mol/L [mean (SD) for neurologically normal controls was 1.16 (0.59) micromol/L], Cr+Crn was 15-29 micro mol/L [reference limit in our laboratory, 79 (38) micromol/L]. Urinary GAA was 2.4-5.8 micro mol/L [reference, 311 (191) micromol/L], and Cr+Crn was 2.1-3.3 mmol/L [reference, 9.9 (4.1) mmol/L]. We found a smaller decrease in GAA and Cr+Crn in some carriers of an AGAT defect. In the patient with GAMT deficiency, plasma and urine GAA was increased (18.6 and 1783 micromol/L, respectively), and Cr+Crn was decreased in plasma (10.7 micromol/L) and urine (2.1 mmol/L). GAA was increased in the parents' plasmas and in the mother's urine. CONCLUSION: The assessment of GAA is a new tool for the detection of both GAMT and AGAT deficiencies.  (+info)

Fresh and cultured thyroid gland: survival and function after implantation. (6/58)

Isogeneic or allogeneic thyroid glands were implanted into thyroidectomized recipeint rats. These grafts, either fresh or cultured, were placed in hamstring muscle pocket or under the renal capsule. Survival and function of the grafts were evaluated by: restoration of normal levels of serum thyroxine, weight gain, kidney transamidinase (a thyroxine-induced enzyme), and histological appearance of re-excised implants. A isografts, fresh and cultured, functioned well as ectopic thyroid glands, though restoration of normal serum thyroxine levels was more rapid for the fresh implants. Fresh allografts functioned transiently but then failed due to rejection. No function was detected for cultured allografts, and rejection was seen histologically. The rat thyroid allograft therefore differs from the rat parathyroid allograft, which often can function for several months despite histological evidence of rejection. Maintenance in tissue culture prior to implantation does not appear to alter the longterm immunogenicity of either organ.  (+info)

Gatm, a creatine synthesis enzyme, is imprinted in mouse placenta. (7/58)

To increase our understanding of imprinting and epigenetic gene regulation, we undertook a search for new imprinted genes. We identified Gatm, a gene that encodes l-arginine:glycine amidinotransferase, which catalyzes the rate-limiting step in the synthesis of creatine. In mouse, Gatm is expressed during development and is imprinted in the placenta and yolk sac, but not in embryonic tissues. The Gatm gene maps to mouse chromosome 2 in a region not previously shown to contain imprinted genes. To determine whether Gatm is located in a cluster of imprinted genes, we investigated the expression pattern of genes located near Gatm: Duox1-2, Slc28a2, Slc30a4 and a transcript corresponding to LOC214616. We found no evidence that any of these genes is imprinted in placenta. We show that a CpG island associated with Gatm is unmethylated, as is a large CpG island associated with a neighboring gene. This genomic screen for novel imprinted genes has elucidated a new connection between imprinting and creatine metabolism during embryonic development in mammals.  (+info)

Studies on the catabolism of Ng-methylarginine, Ng, Ng-dimethylarginine and Ng, Ng-dimethylarginine in the rabbit. (8/58)

1. The routes of elimination of Ng-methylarginine, Ng, Ng-dimethylarginine and Ng, Ng-dimethylarginine were investigated in the rabbit. 2. Analyses showed low plasma concentrations of these amino acids (around 1 nmol/ml) and ratios similar to those found in tissue proteins. The concentrations of these amino acids in extracts of brain, kidney, liver and spleen were similar except that liver had a lower concentration of Ng-methylarginine and Ng, Ng-dimethylarginine. Cerebrospinal fluid contained traces of each amino acid.  (+info)

At least two mutations in the GATM gene cause arginine:glycine amidinotransferase deficiency, a disorder that involves delayed development, intellectual disability, and in some cases muscle weakness. These mutations result in the production of an abnormally shortened arginine:glycine amidinotransferase enzyme or disrupt how genetic information is pieced together to make a blueprint for producing the enzyme.. GATM gene mutations interfere with the ability of the arginine:glycine amidinotransferase enzyme to participate in creatine synthesis, resulting in a shortage of creatine. The effects of arginine:glycine amidinotransferase deficiency are most severe in organs and tissues that require large amounts of energy, especially the brain. ...

Creatine in the form of creatine phosphate plays an important role in ATP regeneration (Fig.1). The human body excretes about two grams of creatine in the form of creatinine via urine daily. Humans replenish creatine stores via either diet or de novo synthesis from glycine and arginine. Creatine is mainly found in red meat (muscle); it is scarce in other types of meat and is largely absent in plants. Vegans and vegetarians rely on de novo synthesis of creatine and place high demand for glycine, arginine, and SAM (methyl donor for GAMT enzyme, the key enzyme in creatine synthesis). It is estimated that 75% of SAH produced in the human body is from GAMT activity. Studies showed that vegans and vegetarians tend to have higher homocysteine levels than the general population and hence elevated SAH.. Glycine is the amino acid that is most frequently conjugated to toxins in human. Glycine is also in high demand for creatine synthesis in vegetarians, vegans, and omnivores with low intake of red meat ...
As a neurotransmitter, glycine affects the functioning of the nervous system, so it is responsible for suppressing the signs of depression, is beneficial for concentration and memory, and is used at bedtime to improve its quality and facilitate the building and regeneration of muscles. In addition, it participates in the synthesis of erythrocytes, haemoglobin and nucleic acid components, is present in the bodys detoxifying processes, participates in glucose and creatine biosynthesis and acts anti-sour and anti-inflammatory.. Glycine is a substance that does not occur on its own. It is, however, a component of numerous supplements - often found in testosterone boosters, creatine stacks, amino acid or carbohydrate protein. According to research, glycine sales last year increased fivefold. It is assumed that supplementation should be 1-3 g of product containing it in its composition. Glycine is also found in natural foods, both in animal and vegetable products, so varied diets. It will also be a ...

BACKGROUND AND PURPOSE: Brain creatine (Cr) deficiencies (BCr-d) are rare disorders of creatine biosynthesis and transport. We performed consecutive measures of total Cr (tCr) and of its phosphorylated fraction, phosphocreatine (PCr), in the brains of children affected by Cr synthesis defects during a long period of therapy. The aim was to identify the optimal treatment strategy for these disorders. MATERIALS AND METHODS: Two patients with guanidinoacetate methyltransferase defect (GAMT-d) were treated with different amounts of Cr and with diet restrictions aimed at reducing endogenous guanidinoacetate (GAA) synthesis. Three patients with arginine:glycine amidinotransferase defect (AGAT-d) were treated with different Cr intakes. The patients treatments were monitored by means of (1)H- and (31)P-MR spectroscopy. RESULTS: Cr and PCr replenishment was lower in GAMT-d than in AGAT-d even when GAMT-d therapy was carried out with a very high Cr intake. Cr and especially PCr replenishment became more ...
Aims: Creatine buffers cellular ATP via the creatine kinase reaction. Creatine levels are reduced in heart failure, but their contribution to pathophysiology is unclear. Arginine:glycine amidinotransferase (AGAT) in the kidney catalyses both the first step in creatine biosynthesis as well as homoarginine synthesis. AGAT-/- mice fed a creatine-free diet have a whole body creatine-deficiency. We hypothesised that AGAT-/- mice would develop cardiac dysfunction and rescue by dietary creatine would imply causality. Methods and results: Withdrawal of dietary creatine in AGAT-/- mice provided an estimate of myocardial creatine efflux of ∼2.7%/day, however, in vivo cardiac function was maintained despite low levels of myocardial creatine. Using AGAT-/- mice naïve to dietary creatine we confirmed absence of phosphocreatine in the heart, but crucially, ATP levels were unchanged. Potential compensatory adaptations were absent, AMPK was not activated and respiration in isolated mitochondria was normal. AGAT-/-
Background: Creatine plays an important role in the storage and transmission of phosphate-bound energy. The cerebral creatine deficiency syndromes (CCDS) comprise three inherited defects in creatine biosynthesis and transport. They are characterized by mental retardation, speech and language delay and epilepsy. All three disorders cause low-creatine signal on brain magnetic resonance spectroscopy (MRS); however, MRS may not be readily available and even when it is, biochemical tests are required to determine the underlying disorder. Methods: Analysis was performed by liquid chromatography-tandem mass spectrometry in positive ionization mode. Samples were analysed underivatized using a rapid dilute and shoot approach. Chromatographic separation of the three compounds was achieved. Stable isotope internal standards were used for quantification. Results: Creatine, creatinine and guanidinoacetate were measured with a 2.5 minute run time. For guanidinoacetate, the standard curve was linear to at ...

Even though homoarginine is excreted by the kidney, we found lower homoarginine levels in persons with impaired kidney function. This may be due to the fact that the kidney is one of the sites for the transaminidation of l-lysine to homoarginine.21,22 In the LURIC study, homoarginine consistently was found to be low in patients with a low estimated glomerular filtration rate,23 and hemodialysis patients (4D study) had even lower concentrations. Because homoarginine is synthesized from the amino acid lysine and is suggested to indicate intestinal absorption of exogenous amino acids,24 it is likely that homoarginine plays a role in the nutritional status of patients. It is thus of particular interest that wasting, a complex process involving muscle loss, poor food intake, and inflammation, frequently develops in patients with chronic heart and kidney disease.25,26 It is conceivable that the low homoarginine levels seen in patients with impaired renal function may contribute to malnutrition and ...
The present data show that creatine supplementation clearly induces elevated GVA and argininic acid levels. It has been suggested that GVA could be synthesized by transamination from arginine and that it can be further metabolized to argininic acid (4, 16). GVA and argininic acid are metabolically related and are elevated in states of hyperargininemia (19). The present findings suggest for the first time that even in the absence of hyperargininemia, the supposed creatine synthesis suppression can lead to upregulation of a secondary pathway of arginine metabolism, i.e., synthesis of GVA and argininic acid. The latter guanidino compounds are convulsants and can inhibit GABA responses in neurons (7, 8), although it should be emphasized that the concentrations reached in the present study are far below the pathological range. Despite the popularity of creatine as a nutritional supplement for ,10 yr, no such side effects on the central nervous system amino acid responses have been reported or ...

Definition of guanidinoacetate N-methyltransferase. Provided by Stedmans medical dictionary and Drugs.com. Includes medical terms and definitions.
Magnetic resonance spectroscopy (MRS) is the only non-invasive, non-radiation-based technique for investigating the metabolism of living tissue. MRS of protons (1H-MRS), which provides the highest sensitivity of all MR-visible nuclei, is a method capable of detecting and quantifying specific cardiac biomolecules, such as lipids and creatine in normal and diseased hearts in both animal models and humans. This can be used to study mechanisms of heart failure development in a longitudinal manner, for example, the potential contribution of myocardial lipid accumulation in the context of ageing and obesity. Similarly, quantifying creatine levels provides insight into the energy storage and buffering capacity in the heart. Creatine depletion is consistently observed in heart failure independent of aetiology, but its contribution to pathophysiology remains a matter of debate. These and other questions can in theory be answered with cardiac MRS, but fundamental technical challenges have limited its use. The

Evidence, however, exists to favor the view that glycine is converted to guanidinoacetic acid which is then methylated to form creatine.1 The first of these reactions probably takes place principally in the kidney and the transfer of free methyl groups occurs chiefly in the liver.. Considerable material has been gathered ...
Jaggumantri et al. recently published an open-label observational study to evaluate the effect of adjunct S-adenosyl methionine (SAM) in Creatine transporter (SLC6A8) deficiency.

Rett syndrome (RTT) is an X-linked severe neurodevelopmental disorder. Despite their good appetite, many females with RTT meet the criteria for moderate to severe malnutrition. The pathological mechanism is barely understood. Although feeding difficulties may play a role in this, other constitutional factors as altered metabolic processes are suspected. Preliminary research showed elevated plasma creatine concentrations and increased urinary creatine/creatinine ratios in half of the RTT girls.. The aim of this study is to confirm previous findings and examine the functionality of the creatine transporter in RTT girls.. The investigators assume that previous findings will be confirmed, and are due to an altered functionality of the creatine transporter. ...
Arginine (Arg) and glycine (Gly) seem to be the only substrates accepted by the amidinotransferase that catalyze the first step of the synthesis pathway of the cyanotoxin cylindrospermopsin (CYN), leading to guanidinoacetate (GAA). Here, the effect of these amino acids on the production of CYN in cultures of the cylindrospermopsin-producing strain, Aphanizomenon ovalisporum UAM-MAO, has been studied. Arg clearly increased CYN content, the increment appearing triphasic along the culture. On the contrary, Gly caused a decrease of CYN, observable from the first day on. Interestingly, the transcript of the gene ntcA, key in nitrogen metabolism control, was also enhanced in the presence of Arg and/or Gly, the trend of the transcript oscillations being like that of aoa/cyr. The inhibitory effect of Gly in CYN production seems not to result from diminishing the activity of genes considered involved in CYN synthesis, since Gly, as Arg, enhance the transcription of genes aoaA-C and cyrJ. On the other hand,

1. By using ion-exchange columns coupled to a sensitive automated Sakaguchi reaction, in addition to the normal ninhydrin reaction for amino acids, homoarginine, a guanidino homologue of arginine, was found in the plasma and urine of both normal and cystinuric individuals.. 2. In all seven cystinuric subjects studied, urinary excretion of homoarginine was approximately ten times that found in normal subjects; the plasma levels of this amino acid were considerably reduced relative to normal individuals.. 3. Homoarginine in the plasma can be derived either metabolically from lysine or from dietary sources.. 4. In normal subjects homoarginine was cleared at a higher rate than arginine. On the other hand, the clearance of arginine exceeded that for homoarginine in the majority of cystinuric subjects although the values obtained for homoarginine indicate that the defect in amino acid transport also affects this amino acid.. 5. The defect in the proximal tubular reabsorption of homoarginine is less ...
Nephrectomized rats may have significantly reduced creatine synthesis rates[509] via impairment of methylation (the GAMT enzyme)[510] although creatine reuptake from the urine seems unimpaired.[511] Supplemental creatine in a rat model of 2/3rds nephrectomy (2% creatine in the diet) does not appear to negatively influence kidney function as assessed by the serum biomarkers of cystatin C and urinary protein or creatinine clearance rates.[512] Elsewhere, 2% creatine in the diet in rats for two weeks again failed to show negative effects on kidney function, but showed benefit in reducing homocysteine in late-stage uremic rats.[312] While there is not much human evidence for the rat nephrectomy model, a lone case study in a man with a single kidney failed to find an impairing effect of creatine (20g daily for five days and 5g for another month) in conjunction with a high protein diet.[513 ...

So its a little from column A and a little from column B? I understand both work, but which is optimal? Surely when both opinions read as facts (at least thats how I read them) one has to be more current and correct. If one states It is generally recommended to take at least 1-2 weeks off from creatine supplementation in order to maintain a proper response mechanism in the body and the other states creatines effect on the body never changes so no need to cycle its use they seem to be mutually exclusive facts (i.e. both cannot be correct - though I understand the latter is more of an absolute)... Ironman (who is obviously very knowledgeable) stated the website information was outdated as opposed to the forum post by ironmaiden708. In my uneducated eyes, I take the last thing I was told as being the most correct since it should be the most recent. Especially when it comes from such a pool of knowledge ...
Rationale: Creatine is thought to be involved in the spatial and temporal buffering of ATP in energetic organs such as heart and skeletal muscle. Creatine depletion affects force generation during maximal stimulation, while reduced levels of myocardial creatine are a hallmark of the failing heart, leading to the widely held view that creatine is important at high workloads and under conditions of pathological stress. Objective: We therefore hypothesised that the consequences of creatine-deficiency in mice would be impaired running capacity, and exacerbation of heart failure following myocardial infarction. Methods and Results: Surprisingly, mice with whole-body creatine deficiency due to knockout of the biosynthetic enzyme (guanidinoacetate N-methyltransferase - GAMT) voluntarily ran just as fast and as far as controls (,10km/night) and performed the same level of work when tested to exhaustion on a treadmill. Furthermore, survival following myocardial infarction was not altered, nor was ...
In regard to the blood brain barrier (BBB), which is a tightly woven mesh of non-fenestrated microcapillary endothelial cells (MCECs) that prevents passive diffusion of many water-soluble or large compounds into the brain, creatine can be taken into the brain via the SLC6A8 transporter.[192] In contrast, the creatine precursor (guanidinoacetate, or GAA) only appears to enter this transporter during creatine deficiency.[192] More creatine is taken up than effluxed, and more GAA is effluxed rather than taken up, suggesting that creatine utilization in the brain from blood-borne sources[192] is the major source of neural creatine.[193][192] However, "capable of passage" differs from "unregulated passage" and creatine appears to have tightly regulated entry into the brain in vivo[193]. After injecting rats with a large dose of creatine, creatine levels increased and plateaued at 70uM above baseline levels. These baseline levels are about 10mM, so this equates to an 0.7% increase when ...

[caption id=attachment_1336 align=alignright width=300] The benefits of creatine supplementation are enough to make this the most researched
Creatine is one of the most popular and widely researched natural supplements. The majority of studies have focused on the effects of creatine monohydrate on performance and health; however, many other forms of creatine exist and are commercially available in the sports nutrition/supplement market. Regardless of the form, supplementation with creatine has regularly shown to increase strength, fat free mass, and muscle morphology with concurrent heavy resistance training more than resistance training alone. Creatine may be of benefit in other modes of exercise such as high-intensity sprints or endurance training. However, it appears that the effects of creatine diminish as the length of time spent exercising increases. Even though not all individuals respond similarly to creatine supplementation, it is generally accepted that its supplementation increases creatine storage and promotes a faster regeneration of adenosine triphosphate between high intensity exercises. These improved outcomes will increase

Discussion. The present results support the findings of previous studies suggesting that creatine supplementation, in conjunction with a good conditioning program, can significantly increase muscular strength and power, to an extent that conditioning programs alone do not match (Haff et al., 2000; Stout et al., 1999). A number of mechanisms have been offered in explanation. First, creatine supplementation increases creatine and phosphocreatine concentration in skeletal muscle, which appears to be directly related to enhancement of force development (Balsom et al., 1995; Casey et al., 1996; Greenhaff et al., 1993; Harris, Soderlund, & Hultman, 1992). Enhanced ability to meet high demand for ATP during maximal exercise may help explain the improvement in muscular strength and power.. The present studys finding of an increase in lean body mass and body weight with creatine supplementation is consistent with other studies (Earnest et al., 1995; Haff et al., 2000; Kreider, Ferreira, et al., 1998; ...

In a very recent study published in the journal, Medicine & Science in Sports & Exercise, researchers from the University of Sao Paolo published their findings on the effects of creatine supplementation along with resistance training on osteoarthritis[1].. As some background, osteoarthritis is the most common form of arthritis which affects over 20 million Americans. It involves primarily the articular cartilage with the synovium or soft tissue lining the joint capsule as well as the subchondral bone itself. The articular cartilage itself gets eroded away and subchondral bone forms.. Back to the recent study… For this particular study, women with osteoarthritis were randomly assigned to either a placebo or creatine group. In total, there were 26 participants in this study with an equal number in each group. Supplementation with creatine started at a dose of 20g/d for 1 week followed by 5 g/d for the remainder of the study (12 weeks total duration).. Both groups participated in a resistance ...

Streptomycin is an aminocyclitol-aminoglycoside antibiotic produced by Streptomyces griseus. Streptomycin consists of aminocyclitol (streptidine), 6-deoxyhexose (streptose), and N-methyl-L-glucosamine moieties, which are formed by independent biosynthetic pathways. All of the moieties are derived from D-glucose. The streptidine moiety is synthesized via myo-inositol, which is then oxidized at C-1 and transaminated to give scyllo-inosamine. After phosphorylation, the compound is transamidinated by arginine. The same procedure is repeated at the C-3 position. The streptose moiety is made from D-glucose via a dTDP-glucose pathway. The exact biosynthetic route for the N-methyl-L-glucosamine moiety is unknown, though the biosynthetic gene cluster have been proposed ...

Dr. Clarks response - Sodium benzoate works by pulling ammonia out of the body. Ammonia is converted to urea for excretion in the urine by going through the urea cycle. The urea cycle starts when ammonia is converted to carbamyl phosphate. Carbamyl phosphate commits the body to making urea. The VERY next reaction consumes ornithine. So when sodium benzoate is given to the GAMT patients the thinking is it is sparing the loss of ornithine by the urea cycle. If ornithine is not consumed by the urea cycle maybe it can stay around to inhibit AGAT. That is the theory. Sodium Benzoate has a long history for treating patients with urea cycle deficits and is generally considered to be safe. It is actually found in some foods as a preservative. Based on its safety and the importance of sparing ornithine I do think the sodium benzoate is a good option for GAMT patients. I think some physicians may be hesitant to use it in GAMT patients because usually sodium benzoate is indicated to decrease ammonia, and ...
