Identification and functional analysis of novel human melanocortin-4 receptor variants. (1/1389)

Inactivation of the melanocortin-4 receptor (MC4-R) by gene-targeting results in mice that develop maturity-onset obesity, hyperinsulinemia, and hyperglycemia. These phenotypes resemble common forms of human obesity, which are late-onset and frequently accompanied by NIDDM. It is not clear whether sequence variation of the MC4-R gene contributes to obesity in humans. Therefore, we examined the human MC4-R gene polymorphism in 190 individuals ascertained on obesity status. Three allelic variants were identified, including two novel ones, Thr112Met and Ile137Thr. To analyze possible functional alterations, the variants were cloned and expressed in vitro and compared with the wild-type receptor. One of the novel variants, Ile137Thr, identified in an extremely obese proband (BMI 57), was found to be severely impaired in ligand binding and signaling, raising the possibility that it may contribute to development of obesity. Furthermore, our results also suggest that sequence polymorphism in the MC4-R coding region is unlikely to be a common cause of obesity in the population studied, given the low frequency of functionally significant mutations.  (+info)

Basolateral sorting of furin in MDCK cells requires a phenylalanine-isoleucine motif together with an acidic amino acid cluster. (2/1389)

Furin is a subtilisin-related endoprotease which processes a wide range of bioactive proteins. Furin is concentrated in the trans-Golgi network (TGN), where proteolytic activation of many precursor proteins takes place. A significant fraction of furin, however, cycles among the TGN, the plasma membrane, and endosomes, indicating that the accumulation in the TGN reflects a dynamic localization process. The cytosolic domain of furin is necessary and sufficient for TGN localization, and two signals are responsible for retrieval of furin to the TGN. A tyrosine-based (YKGL) motif mediates internalization of furin from the cell surface into endosomes. An acidic cluster that is part of two casein kinase II phosphorylation sites (SDSEEDE) is then responsible for retrieval of furin from endosomes to the TGN. In addition, the acidic EEDE sequence also mediates endocytic activity. Here, we analyzed the sorting of furin in polarized epithelial cells. We show that furin is delivered to the basolateral surface of MDCK cells, from where a significant fraction of the protein can return to the TGN. A phenylalanine-isoleucine motif together with the acidic EEDE cluster is required for basolateral sorting and constitutes a novel signal regulating intracellular traffic of furin.  (+info)

Identification of a Leu-lle internalization motif within the cytoplasmic domain of the leukaemia inhibitory factor receptor. (3/1389)

Leukaemia inhibitory factor (LIF) signals via a heterodimeric receptor complex comprised of the LIF receptor (LIFR) and the interleukin (IL)-6 signal transducer gp130. Upon binding to its cognate receptor LIF is internalized. In this study, we show that the LIFR is endocytosed independently of gp130. By using a heterochimaeric receptor system we identified a dileucine-based internalization motif within the cytoplasmic domain of the LIFR. Our findings suggest that a heterodimeric LIFR/gp130 complex and homodimeric gp130/gp130 complex are endocytosed via distinct internalization signals.  (+info)

Role of bkdR, a transcriptional activator of the sigL-dependent isoleucine and valine degradation pathway in Bacillus subtilis. (4/1389)

A new gene, bkdR (formerly called yqiR), encoding a regulator with a central (catalytic) domain was found in Bacillus subtilis. This gene controls the utilization of isoleucine and valine as sole nitrogen sources. Seven genes, previously called yqiS, yqiT, yqiU, yqiV, bfmBAA, bfmBAB, and bfmBB and now referred to as ptb, bcd, buk, lpd, bkdA1, bkdA2, and bkdB, are located downstream from the bkdR gene in B. subtilis. The products of these genes are similar to phosphate butyryl coenzyme A transferase, leucine dehydrogenase, butyrate kinase, and four components of the branched-chain keto acid dehydrogenase complex: E3 (dihydrolipoamide dehydrogenase), E1alpha (dehydrogenase), E1beta (decarboxylase), and E2 (dihydrolipoamide acyltransferase). Isoleucine and valine utilization was abolished in bcd and bkdR null mutants of B. subtilis. The seven genes appear to be organized as an operon, bkd, transcribed from a -12, -24 promoter. The expression of the bkd operon was induced by the presence of isoleucine or valine in the growth medium and depended upon the presence of the sigma factor SigL, a member of the sigma 54 family. Transcription of this operon was abolished in strains containing a null mutation in the regulatory gene bkdR. Deletion analysis showed that upstream activating sequences are involved in the expression of the bkd operon and are probably the target of bkdR. Transcription of the bkd operon is also negatively controlled by CodY, a global regulator of gene expression in response to nutritional conditions.  (+info)

Demonstration of a new mammalian isoleucine catabolic pathway yielding an Rseries of metabolites. (5/1389)

1. Normal human urine contains small amounts (less than 4 mg/g of creatinine) of 2-ethylhydracrylic acid, formed, we believe, by a previously undisclosed endogenous catabolic pathway for the oxidation of a newly described series of R metabolites of isoleucine. 2. Urinary excretion of 2-ethylhydracrylic acid is variably increased in defects of isoleucine oxidation at distal steps in the catabolic pathway (3-oxoacyl-CoA thiolase deficiency and methylmalonyl-CoA mutase deficiency) and is diminished when proximal steps of the oxidative pathway are blocked as in branched-chain oxo acid decarboxylase deficiency ('maple-syrup-urine' disease). 3. Precursors of R-pathway metabolites [R(-)-2-methylbutyrate and 2-ethylacrylate ] lead to increased 2-ethylhydracrylate excretion in the mammal(rat, rabbit and dog); the corresponding S metabolites [S(+)-2-methylbutyric acid and tiglic acid ], when given in equimolar amounts, have little effect on its excretion, suggesting that little or no interconversion between S and R metabolites occurs in vivo. 4. Studies with 2H-labelled precursors indicate that conversion of R 2-methylbutyrate into 2-ethylhydracrylic acid occurs by a direct pathway (apparently via 2-ethylacrylic acid). 5. The further oxidation of 2-ethylhydracrylic acid to ethylmalonic acid was demonstrated, and may be analogous to S-metabolite oxidation via methyl malonate. 6. Valine metabolites do not interact with the R=isoleucine pathway under the conditions of these experiments in vivo.  (+info)

Conformational change in the human glucocorticoid receptor induced by ligand binding is altered by mutation of isoleucine 747 by a threonine. (6/1389)

Limited proteolysis experiments were performed to study conformation changes induced by ligand binding on in vitro produced wild-type and I747T mutant glucocorticoid receptors. Dexamethasone-induced conformational changes were characterized by two resistant proteolysis fragments of 30 and 27 kDa. Although dexamethasone binding affinity was only slightly altered by the I747T substitution (Roux, S., Terouanne, B., Balaguer, P., Loffreda-Jausons, N., Pons, M., Chambon, P., Gronemeyer, H., and Nicolas, J.-C. (1996) Mol. Endocrinol. 10, 1214-1226), higher dexamethasone concentrations were required to obtain the same proteolysis pattern. This difference was less marked when proteolysis experiments were conducted at 0 degrees C, indicating that a step of the conformational change after ligand binding was affected by the mutation. In contrast, RU486 binding to the wild-type receptor induced a different conformational change that was not affected by the mutation. Analysis of proteolysis fragments obtained in the presence of dexamethasone or RU486 indicated that the RU486-induced conformational change affected the C-terminal part of the ligand binding domain differently. These data suggest that the ligand-induced conformational change occurs via a multistep process. In the first step, characterized by compaction of the ligand binding domain, the mutation has no effect. The second step, which stabilizes the activated conformation and does not occur at 4 degrees C, seems to be a key element in the activation process that can be altered by the mutation. This step could involve modification of the helix H12 position, explaining why the conformation induced by RU486 is not affected by the mutation.  (+info)

Different targets for the fragile X-related proteins revealed by their distinct nuclear localizations. (7/1389)

Fragile X syndrome is caused by the absence of the fragile X mental retardation protein (FMRP). FMRP and its structural homologues FXR1P and FXR2P form a family of RNA-binding proteins (FXR proteins). The three proteins associate with polyribosomes as cytoplasmic mRNP particles. Here we show that small amounts of FMRP, FXR1P and FXR2P shuttle between cytoplasm and nucleus. Mutant FMRP of a severely affected fragile X patient (FMRPI304N) does not associate with polyribosomes and shuttles more frequently than normal FMRP, indicating that the association with polyribosomes regulates the shuttling process. Using leptomycin B we demonstrate that transport of the FXR proteins out of the nucleus is mediated by the export receptor exportin1. Finally, inactivation of the nuclear export signal in two FXR proteins shows that FMRP shuttles between cytoplasm and nucleoplasm, while FXR2P shuttles between cytoplasm and nucleolus. Therefore, molecular dissection of the shuttling routes used by the FXR proteins suggests that they transport different RNAs.  (+info)

cdc25A is necessary but not sufficient for optimal c-myc-induced apoptosis and cell proliferation of vascular smooth muscle cells. (8/1389)

Increasing evidence indicates that the control of cell proliferation and apoptosis are linked. The c-myc proto-oncogene is induced early after cell-cycle entry in vascular smooth muscle cells (VSMCs) in vitro and after arterial injury and regulates both cell proliferation and apoptosis. Although both proliferation and apoptosis are likely to be mediated via transcriptional activation of target genes, few c-myc targets have been identified. Therefore, the recent identification that cdc25A, a cell-cycle phosphatase involved in G1 progression, is transcriptionally activated by c-myc and regulates c-myc-induced apoptosis has suggested that cdc25A may be the principal mediator of c-myc in VSMCs. We examined cdc25A regulation of c-myc-induced proliferation and apoptosis by expressing cdc25A or antisense cdc25A in primary rat VSMCs or in VSMCs expressing deregulated c-myc or adenovirus E1A. Ectopic c-myc increased cdc25A expression, but cdc25A was still responsive to serum components, which indicated that c-myc alone is not the main determinant of cdc25A expression. Antisense cdc25A inhibited c-myc-induced proliferation and apoptosis; however, drug and metabolic blocks indicated that this effect was limited to G1. Ectopic cdc25A augmented the proproliferative and proapoptotic action of c-myc but did not increase cell proliferation or apoptosis in the absence of ectopic c-myc. In contrast, E1A/E2F-induced apoptosis was independent of cdc25A. We conclude that cdc25A expression modulates the ability of c-myc to induce apoptosis in G1. However, cdc25A alone does not induce apoptosis and cannot substitute for c-myc in VSMCs. Additional targets of c-myc are therefore involved in apoptosis of both G1 and post-G1 VSMCs.  (+info)

Aceptado el Agosto 19, 2008. Abstract. The stability constants of Cu2+, Mn2+ and UO22+ complexes with isoleucine were determined by paper electrophoretic technique. Present method is based upon the migration of a spot of the metal ions on a paper strip at different pHs of background electrolyte. A graph of pH against mobility gives information about the binary complexes and permit to calculate their stability constants. The first and second stability constants of [Cu(II) isoleucine], [Mn(II) isoleucine] and [UO2(II) isoleucine] complexes were found to be (8.41 ± 0.07; 6.43 ± 0.03), (3.87 ± 0.11; 2.61 ± 0.06) and (7.91 ± 0.13; 5.73 ± 0.04) for Cu(II), Mn(II) and UO2(II) complexes, respectively at ionic strength 0.1 Mol/L and a temperature of 35 0C.

P4-ATPases (flippases) translocate specific phospholipids such as phosphatidylserine from the exoplasmic leaflet of the cell membrane to the cytosolic leaflet, upholding an essential membrane asymmetry. The mechanism of flipping this giant substrate has remained an enigma. We have investigated the importance of amino acid residues in transmembrane segment M4 of mammalian P4-ATPase ATP8A2 by mutagenesis. In the related ion pumps Na+, K+-ATPase and Ca2+-ATPase, M4 moves during the enzyme cycle, carrying along the ion bound to a glutamate. In ATP8A2, the corresponding residue is an isoleucine, which recently was found mutated in patients with cerebellar ataxia, mental retardation, and dysequilibrium syndrome. Our analyses of the lipid substrate concentration dependence of the overall and partial reactions of the enzyme cycle in mutants indicate that, during the transport across the membrane, the phosphatidylserine head group passes near isoleucine-364 (I364) and that I364 is critical to the release of the
oxidation of the lipid fraction of egg yolk results in the formation of peroxy, alkoxy, and lipid free radicals that can also react with egg proteins (Karpowicz 1981).. Hydrolysates of light-aged glue paint films contained higher concentrations of isoleucine than the corresponding unexposed paints. A possible explanation for this result is that clusters of bulky alkyl groups, such as isoleucine, present a steric hindrance to hydrolysis, resulting in reduced isoleucine yields from hydrolysates of fresh, unaged proteins (Pellett 1981; Pickering and Newton 1990). Aging causes denaturing and partial disruption of the protein structure (Karpowicz 1981), exposing the alkyl group clusters to the action of aqueous acid, thereby causing improved hydrolysis yields. Another explanation for the higher concentration of isoleucine in aged samples is that a species formed during aging may coelute with isoleucine. GC-MS could be used to test this hypothesis but was not employed in this study.. Regarding the ...

Isoleucine, an essential amino acid, is one of the three amino acids having branched hydrocarbon side chains. It is usually interchangeable with leucine and occasionally with valine in proteins. The side chains of these amino acids are not reactive and therefore not involved in any covalent chemistry in enzyme active centers. However, these residues are critically important for ligand binding to proteins, and play central roles in protein stability. Note also that the β carbon of isoleucine is optically active, just as the β carbon of threonine. These two amino acids, isoleucine and threonine, have in common the fact that they have two chiral centers. ...
Mpc proteins are highly conserved from yeast to humans and are necessary for the uptake of pyruvate at the inner mitochondrial membrane, which is used for leucine and valine biosynthesis and as a fuel for respiration. Our analysis of the yeast MPC gene family suggests that amino acid biosynthesis, respiration rate and oxidative stress tolerance are regulated by changes in the Mpc protein composition of the mitochondria. Mpc2 and Mpc3 are highly similar but functionally different: Mpc2 is most abundant under fermentative non stress conditions and important for amino acid biosynthesis, while Mpc3 is the most abundant family member upon salt stress or when high respiration rates are required.

My tub of Juiced Aminos is diesel looking! All black with red and white lettering, and a bad ass dude training in the middle of it all like a ghost.. This tub is covered in tons of information about the product, about Universal, and about how to use Juiced Aminos. The only thing that isnt really highlighted or written out clearly is the ingredients. The big one I want to mention is the blend to be more specific. This Leucine, IsoLeucine, and Valine blend also come with Lysine, Methionine, Phenylalanine, Threonine, and Histidine. All nine of these ingriendients make up Universals Anabolic BCAA & EAA Matrix totaling 6000mg once its all blended together. When I am training and using BCAAs as a tool I like to have a blend of Leucine, IsoLeucine, and Valine equaling 15 grams or just less. SO for Universal to have all those extra ingredients and only hitting 6000mg total.. I would be forced to eat tons and tons of this stuff to hit my same marks.. But even if that was my option there is no way to ...

Two different pyridoxal 5-phosphate-containing L-threonine deaminases (EC 4.3.1.19 [EC] ), biosynthetic and biodegradative, which catalyze the deamination of L-threonine to \alpha-ketobutyrate, are present in Escherichia coli and Salmonella typhimurium. Biodegradative threonine deaminase (TdcB) catalyzes the first reaction in the anaerobic breakdown of L-threonine to propionate. TdcB, unlike the biosynthetic threonine deaminase, is insensitive to L-isoleucine and is activated by AMP. In the present study, TdcB from S. typhimurium was cloned and overexpressed in E. coli. In the presence of AMP or CMP, the recombinant enzyme was converted to the tetrameric form accompanied by significant enzyme activation. To provide insights into ligand-mediated oligomerization and enzyme activation, crystal structures of S. typhimurium TdcB and its complex with CMP were determined. In the native structure, TdcB is in a dimeric form, whereas in the TdcB·CMP complex, it exists in a tetrameric form with 222 ...

A novel fluorescence sensing system for branched-chain amino acids (BCAAs)was developed based on engineered leucine/isoleucine/valine-binding proteins (LIVBPs)conjugated with environmentally sensitive fluorescence probes. LIVBP was cloned fromEscherichia coli and Gln149Cys, Gly227Cys, and Gln254Cys mutants were generated bygenetic engineering. The mutant LIVBPs were then modified with environmentallysensitive fluorophores. Based on the fluorescence intensity change observed upon thebinding of the ligands, the MIANS-conjugated Gln149Cys mutant (Gln149Cys-M) showedthe highest and most sensitive response. The BCAAs Leu, Ile, and Val can each bemonitored at the sub-micromolar level using Gln149Cys-M. Measurements were alsocarried out on a mixture of BCAFAs and revealed that Gln149Cys-M-based measurementis not significantly affected by the change in the molar ratio of Leu, Ile and Val in thesample. Its high sensitivity and group-specific molecular recognition ability make the newsensing system ideally suited
This study conducted to evaluate the effect of prebiotics (Fermacto) and isoleucine and their combination on performance and some blood parameters of broiler chickens during finisher period. At the first of experiment 300 one-day-old mixed Ross broiler chicks reared in same condition according to Ross manual guide up to 21 days old. Chicks at 21 day old were randomly allocated to 20 groups of 15 birds in a completely randomized design with 4 treatments and 5 replications. Control group were fed with the basal diet of corn-soya and wheat. In the experimental group, 0.1% of prebiotics and 0.04% isoleucine were added. Weight gain and feed intake of birds were measured and at the end of the experiment one bird from each pen were sampled and weighed and then killed. The results showed that prebiotics and isoleucine significantly (P|0.05) improved feed conversion and weight gain and serum cholesterol but it did not have any significant effect on traits such as feed, the serum amount of urea, uric acid,

Consisting of isoleucine, leucine and valine, branched chain amino acids (BCAA) are nutrients that the body needs but cant produce on its own, requiring a dietary or supplemental source. Foods that are rich in BCAA include meat, dairy and soy products, as well as poultry and eggs. Leucine, which was discovered in the early 19th century, is widely considered to be the most prominent of the branched chain amino acids, but the three work together to offer a number of health-supporting qualities. Branched chain amino acids are the building blocks of protein, and are perhaps most famous for their important role in muscle growth, maintenance and repair.**. Branched chain amino acids have become increasingly popular with athletes, particularly those involved in weight training, due to their ability to modulate the metabolism of muscle protein. In fact, science has shown that BCAA make up approximately one-third of the protein found in muscle. Studies have indicated that BCAA are rapidly absorbed into ...

As for the two other BCAAs - isoleucine and leucine - they dont have the stellar muscle-building reputation of leucine, but theyre important in post-workout recovery, nonetheless.. Isoleucine also has an important muscle-building benefit - helping maintain a positive nitrogen balance. When that happens, your muscles will thrive in an anabolic environment.. In terms of post-workout benefits, isoleucine is crucial when it comes to recovery because it helps increase endurance and repair muscle tissue.. As for valine, it also plays a role in maintaining a positive nitrogen balance for muscle growth. Plus, it helps increase energy and endurance levels..

The β2-AR is a major lipolytic receptor in human fat cells. With the notion that the β2-AR polymorphisms might play a role in obesity, Large et al. (1997)genotyped 140 women with a large variation in body fat mass. The Glu27 homozygotes had an average fat mass excess of 20 kg (Large et al., 1997, Table 1). Neither allele at the Arg16Gly polymorphism was linked to obesity. An investigation of obese men did not give a similar result (Hellstrom et al., 1999). These findings in women will probably stimulate further work and may be applied to the known interethnic variability in obesity.. The codon 164 threonine/isoleucine polymorphism of β2-AR has not received much attention in humans because of the comparative rarity of the less frequent (isoleucine) allele. To investigate the functional significance of this polymorphism in the myocardium, Turki et al. (1996) prepared transgenic mice expressing 45 times the normal endogenous β2-AR. Mice with the mutant 164 Ile and mice with the wild-type ...

How and when should you take BCAAs ? Usually 4-10 grams of BCAAs (combined, not of each BCAA) before and after a workout is the best dose for most people. Of course, those with body weight between 100-150lbs would take a smaller dose (4-5 grams) while those 150 and above would tend toward the higher side (8-10 grams). The best way to take these supplements is to monitor how you feel on them and take a month to use them before a workout only, then a month to do after, then both and analyze which method gave you the best results! Some people like to mix BCAAs in their water bottle and drink while they workout. Obviously, there are many ways to use this supplement! Everyones body is a bit different, so trial and evaluation is the only way to find the best fit for you ...

1. The oxidation of the three branched-chain amino acids was regulated in parallel fashion in rat tissues studied in vitro. 2. With 0.1 mM-[1-14C]isoleucine as substrate in the presence of 5.5 mM-glucose, 14CO2 production was 0.6 mumol/2 h per g in the aorta, 0.3 in peripheral nerve, 0.2 in muscle and 0.13 in spinal cord. 3. The ratio 14C oxidized/14C incorporated into proteins with 0.1 mM-[1-14C]leucine was 1.3 in hemidiaphragms, 3.3 in sciatic nerve and 1.0 in nerves undergoing Wallerian degeneration. Leucine oxidation decreased only slightly during degeneration, but protein synthesis doubled. 4. Hemidiaphragms incubated with [1-14C]leucine or 4-methyl-2-oxo[1-14C]pentanoate increased 14CO2 production 7-9-fold as substrate concentration was increased from 0.1 to 0.5 mM; under the same conditions 14CO2 production by nerves increased only 2-3-fold. 5. 2-Oxoglutarate stimulated the oxidation of the branched-chain amino acids by muscles and peripheral nerves and the oxidation of ...

Proteins have evolved to balance the structural requirements for stability with the need for specialised conformations imparting catalytic activity and ligand-binding capabilities. The glutathione transferases (GSTs) are a multi-gene family of ubiquitous proteins that are predominantly involved in the detoxification of reactive endo- and xenobiotic compounds through conjugation to the tripeptide glutathione. The family of cytosolic GSTs contain a canonical structure composed of a thioredoxin-like fold in domain 1 and an all-α-helical domain 2. Domain 1 of the cytosolic GSTs contains a highly conserved isoleucine residue in α-helix 3, located below the active site at position 71 in human class Alpha glutathione transferase A1-1 (hGST A1-1), that is involved in maintaining the packing within the hydrophobic core of domain 1. The objective of this study was to provide insight into the role of the topologically conserved Ile-71 residue in the structure, stability, and the catalytic and ...

This study aimed to determine the effects of diets chronically supplemented with branched-chain amino acids (BCAA) on the fatigue mechanisms of trained rats. Thirty-six adult Wistar rats were trained for six weeks. The training protocol consisted of bouts of swimming exercise (one hour a day, five times a week, for six weeks). The animals received a control diet (C) (n = 12), a diet supplemented with 3.57% BCAA (S1) (n = 12), or a diet supplemented with 4.76% BCAA (S2) (n = 12). On the last day of the training protocol, half the animals in each group were sacrificed after one hour of swimming (1H), and the other half after a swimming exhaustion test (EX). Swimming time until exhaustion was increased by 37% in group S1 and reduced by 43% in group S2 compared to group C. Results indicate that the S1 diet had a beneficial effect on performance by sparing glycogen in the soleus muscle (p | 0.05) and by inducing a lower concentration of plasma ammonia, whereas the S2 diet had a negative effect on performance

1c) N,N-dihydroxy-L-valine = (E)-2-methylpropanal oxime + CO2 + H2O. Other name(s): CYP79D1; CYP79D2. Systematic name: L-valine,[reduced NADPH hemoprotein reductase]:oxygen oxidoreductase (N-hydroxylating). Comments: A cytochrome P-450 (heme-thiolate) protein. This enzyme catalyses two successive N-hydroxylations of L-valine, the committed step in the biosynthesis of the cyanogenic glucoside linamarin in Manihot esculenta (cassava). The product of the two hydroxylations, N,N-dihydroxy-L-valine, is labile and undergoes dehydration and decarboxylation that produce the (E) isomer of the oxime. It is still not known whether the decarboxylation is spontaneous or catalysed by the enzyme. The enzyme can also accept L-isoleucine as substrate, with a lower activity. It is different from EC 1.14.14.39, isoleucine N-monooxygenase, which prefers L-isoleucine.. Links to other databases: BRENDA, EXPASY, KEGG, MetaCyc, CAS registry number: References:. 1.

This report presents the results of three experiments on a recombinant plasmid called the ilv 1 plasmid. This plasmid carries the ilv 1 gene of Saccharomyces cerevisiae which produces Threonine deaminase. In the first experiment the presence of this plasmid in a strain of S. cerevisiae called 3971 (i1v 1) is proven by the observation that 50% of the cells in a given clone will segregate the ilv 1 plasmid. The second experiment involved the determination of the specific activity of Threonine deaminase in strain 3971 (i1 v 1) and a wild type strain, CBII, after growing the cells in repressing (+I1e) and non-repressing (-lIe) media. The results show that the basal level of Threonine daminase in 3971 (i1v 1) is four-fold that of the control, CBll. The specific activity of Threonine dearninase in 3971 (i1v 1) cultured non-repressing medium is I5-fold the specific activity of Threonine daminase in repressing medium. The result however does not prove that the ilv 1 gene is being regulated by lIe ...
Branch Chain Amino Acids (BCAA). Branched-chain amino acid (BCAA) is the name given to three of the eight essential amino acids needed to make protein: leucine, isoleucine and valine. They are called branched-chain because their structure has a branch off the main trunk of the molecule. The combination of these three essential amino acids makes up approximately one-third of skeletal muscle in the human body. The body cannot produce BCAAs on its own, but must obtain through diet or supplementation. In order to get energy, the body can actually break down muscle in order to obtain BCAAs. By supplementing BCAAs during and after your workout, you can help prevent muscle tissue breakdown, which occurs as a natural part of metabolism.. ...
Of the eight essential amino acids that cannot be produced by the body‚ the three branched-chain aminos Leucine‚ Isoleucine and Valine are of key importance. Based on their unique structure‚ activity‚ storage and metabolism‚ BCAAs have become a staple in the lives of many athletes and physically active individuals. They account for nearly 1/3 of the amino acids in muscle protein‚ and play a number of key roles in the repair and growth of muscle tissues. These statements have not been evaluated by the Food and Drug Administration (FDA). These products are not meant to diagnose‚ treat or cure any disease or medical condition.

BCAA adalah singkatan dari Branch Chain Amino Acids. BCAA merupakan salah satu suplemen yang paling dicari karena paling efektif membangun otot dan meningkatkan kinerja dan performa fisik bagi siapapun yang mengkonsumsinya.
BCAA means branched chain amino acid and it is progressively being acknowledged as an essential supplement within the area of sports diet. Muscleenergy has its own super plus version of the supplement pre workout BCAAs Branched Chain Amino Acid + Vitamin B6. In a nutshell the word describes three proteinogenic amino acids essential Aminos - leucine, isoleucine and valine.. BCCAs are broadly referred to as foundations of protein. When protein meals are eaten it will get digested into individual proteins and short chains of proteins which are sufficiently little to become made available to the blood stream. Theyre then utilized by your body to construct and repair tissue among other activities.. Amino acids are organic compounds that contain two groups of molecules: amino (-NH2) and carboxyl (-COOH). There are a total of 19 amino acids in the human diet, of which 11 are non-essential, and the remaining 8 are essential. It is this critically important fact that there are 2 kinds of amino acids -- ...

Most archaea and bacteria use a modified C in the anticodon wobble position of isoleucine tRNA to base pair with A but not with G of the mRNA. This allows the tRNA to read the isoleucine codon AUA without also reading the methionine codon AUG. To understand why a modified C, and not U or modified U, is used to base pair with A, we mutated the C34 in the anticodon of Haloarcula marismortui isoleucine tRNA (tRNA2Ile) to U, expressed the mutant tRNA in Haloferax volcanii, and purified and analyzed the tRNA. Ribosome binding experiments show that although the wild-type tRNA2Ile binds exclusively to the isoleucine codon AUA, the mutant tRNA binds not only to AUA but also to AUU, another isoleucine codon, and to AUG, a methionine codon. The G34 to U mutant in the anticodon of another H. marismortui isoleucine tRNA species showed similar codon binding properties. Binding of the mutant tRNA to AUG could lead to misreading of the AUG codon and insertion of isoleucine in place of methionine. This result ...

From UniProt:. Maple syrup urine disease, mild variant (MSUDMV): A mild form of maple syrup urine disease, a metabolic disorder due to an enzyme defect in the catabolic pathway of the branched-chain amino acids leucine, isoleucine, and valine. Accumulation of these 3 amino acids and their corresponding keto acids leads to encephalopathy and progressive neurodegeneration. Clinical features include mental and physical retardation, feeding problems, and a maple syrup odor to the urine. The keto acids of the branched-chain amino acids are present in the urine. If untreated, maple syrup urine disease can lead to seizures, coma, and death. The disease is often classified by its pattern of signs and symptoms. The most common and severe form of the disease is the classic type, which becomes apparent soon after birth. Variant forms of the disorder become apparent later in infancy or childhood and are typically milder, but they still involve developmental delay and other medical problems if not treated. ...
