A province of Canada on the Pacific coast. Its capital is Victoria. The name given in 1858 derives from the Columbia River which was named by the American captain Robert Gray for his ship Columbia which in turn was named for Columbus.

Control of expression of one-carbon metabolism genes of Saccharomyces cerevisiae is mediated by a tetrahydrofolate-responsive protein binding to a glycine regulatory region including a core 5'-CTTCTT-3' motif. (1/33)Expression of yeast genes involved in one-carbon metabolism is controlled by glycine, by L-methionine, and by nitrogen sources. Here we report a novel control element containing a core CTTCTT motif mediating the glycine response, demonstrating that a protein binds this element, that binding is modulated by tetrahydrofolate, and that folate is required for the in vivo glycine response. In an heterologous CYC1 promoter the region needed for the glycine response of GCV2 (encoding the P-subunit of glycine decarboxylase) mediated repression that was relieved by glycine. It was also responsible for L-methionine control but not nitrogen repression. GCV1 and GCV3 have an homologous region in their promoters. The GCV1 region conferred a glycine response on an heterologous promoter acting as a repressor or activator depending on promoter context. A protein was identified that bound to the glycine regulatory regions of GCV1 and GCV2 only if the CTTCTT motif was intact. This protein protected a 17-base pair CATCN7CTTCTT region of GCV2 that is conserved between GCV1 and GCV2. Protein binding was increased by tetrahydrofolate, and use of a fol1 deletion mutant indicated the involvement of a folate in the in vivo glycine response. Tetrahydrofolate or a derivative may act as a ligand for the transcription factor controlling expression of one-carbon metabolism genes. (+info)
Role for the leucine-responsive regulatory protein (Lrp) as a structural protein in regulating the Escherichia coli gcvTHP operon. (2/33)The Escherichia coli glycine-cleavage enzyme system (gcvTHP and lpd gene products) provides C1 units for cellular methylation reactions. Both the GcvA and leucine-responsive regulatory (Lrp) proteins are required for regulation of the gcv operon. One model proposed for gcv regulation is that Lrp plays a structural role, bending the DNA to allow GcvA to function as either an activator or a repressor in response to environmental signals. This hypothesis was tested by replacing all but the upstream 22 bp of the Lrp-binding region in a gcvT::lacZ fusion with the I1A site from phage lambda. Integration host factor (IHF) binds the I1A site and bends the DNA about 140 degrees. Shifting the I1A site by increments of 1 base around the DNA helix resulted in IHF-dependent activation and repression of gcvT::lacZ expression that were face-of-the-helix dependent. Activation was also dependent on the GcvA protein, and repression was dependent on both the GcvA and GcvR proteins, demonstrating that the roles for these proteins were not altered. The results are consistent with Lrp playing primarily a structural role in gcv regulation, although they do not completely rule out the possibility that Lrp also interacts with another gcv-regulatory protein or with RNA polymerase.

Identification of the folate binding sites on the Escherichia coli T-protein of the glycine cleavage system. (3/33)T-protein is a component of the glycine cleavage system and catalyzes the tetrahydrofolate-dependent reaction. To determine the folate-binding site on the enzyme, 14C-labeled methylenetetrahydropteroyltetraglutamate (5,10-CH2-H4PteGlu4) was enzymatically synthesized from methylenetetrahydrofolate (5, 10-CH2-H4folate) and [U-14C]glutamic acid and subjected to cross-linking with the recombinant Escherichia coli T-protein using 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide, a zero-length cross-linker between amino and carboxyl groups. The cross-linked product was digested with lysylendopeptidase, and the resulting peptides were separated by reversed-phase high performance liquid chromatography. Amino acid sequencing of the labeled peptides revealed that three lysine residues at positions 78, 81, and 352 were involved in the cross-linking with polyglutamate moiety of 5, 10-CH2-H4PteGlu4. The comparable experiment with 5,10-CH2-H4folate revealed that Lys-81 and Lys-352 were also involved in cross-linking with the monoglutamate form. Mutants with single or multiple replacement(s) of these lysine residues to glutamic acid were constructed by site-directed mutagenesis and subjected to kinetic analysis. The single mutation of Lys-352 caused similar increase (2-fold) in Km values for both folate substrates, but that of Lys-81 affected greatly the Km value for 5,10-CH2-H4PteGlu4 rather than for 5,10-CH2-H4folate. It is postulated that Lys-352 may serve as the primary binding site to alpha-carboxyl group of the first glutamate residue nearest the p-aminobenzoic acid ring of 5,10-CH2-H4folate and 5,10-CH2-H4PteGlu4, whereas Lys-81 may play a key role to hold the second glutamate residue through binding to alpha-carboxyl group of the second glutamate residue.

The amino-terminal region of the Escherichia coli T-protein of the glycine cleavage system is essential for proper association with H-protein. (4/33)T-protein is a component of the glycine cleavage system and catalyzes the tetrahydrofolate-dependent reaction. Our previous work on Escherichia coli T-protein (ET) showed that the lack of the N-terminal 16 residues caused a loss of catalytic activity [Okamura-Ikeda, K., Ohmura, Y., Fujiwara, K. and Motokawa, Y. (1993) Eur. J. Biochem. 216, 539-548]. To define the role of the N-terminal region of ET, a series of deletion mutants were constructed by site-directed mutagenesis and expressed in E. coli. Deletions of the N-terminal 4, 7 and 11 residues led to reduction in the activity to 42, 9 and 4%, respectively, relative to the wild-type enzyme (wtET). The mutant with 7-residue deletion (ETDelta7) was purified and analyzed. ETDelta7 exhibited a marked increase in Km (25-fold) for E. coli H-protein (EH) accompanied by a 10-fold decrease in kcat compared with wtET, indicating the importance of the N-terminal region in the interaction with EH. The role of this region in the ET-EH interaction was investigated by cross-linking of wtET-EH or ETDelta7-EH complex with 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide, a zero-length cross-linker, in the presence of folate substrates. The resulting tripartite cross-linked products were cleaved with lysylendopeptidase and V8 protease. After purification by reversed-phase HPLC, the cross-linked peptides were subjected to Edman sequencing. An intramolecular cross-linking between Asp34 and Lys216 of wtET which was not observed in wtET alone and an intermolecular cross-linking between Lys288 of wtET and Asp-43 of EH were identified. In contrast, no such cross-linking was detected from the cross-linked product of ETDelta7. These results suggest that EH, when it interacts with ET, causes a change in conformation of ET and that the N-terminal region of ET is essential for the conformational change leading to the proper interaction with EH.

Regulation of the balance of one-carbon metabolism in Saccharomyces cerevisiae. (5/33)One-carbon metabolism in yeast is an essential process that relies on at least one of three one-carbon donor molecules: serine, glycine, or formate. By a combination of genetics and biochemistry we have shown how cells regulate the balance of one-carbon flow between the donors by regulating cytoplasmic serine hydroxymethyltransferase activity in a side reaction occurring in the presence of excess glycine. This control governs the level of 5,10-methylene tetrahydrofolate (5,10-CH(2)-H(4)folate) in the cytoplasm, which has a direct role in signaling transcriptional control of the expression of key genes, particularly those encoding the unique components of the glycine decarboxylase complex (GCV1, GCV2, and GCV3). Based on these and other observations, we propose a model for how cells balance the need to supplement their one-carbon pools when charged folates are limiting or when glycine is in excess. We also propose that under normal conditions, cytoplasmic 5,10-CH(2)-H(4)folate is mainly directed to generating methyl groups via methionine, whereas one-carbon units generated from glycine in mitochondria are more directed to purine biosynthesis. When glycine is in excess, 5, 10-CH(2)-H(4)folate is decreased, and the regulation loop shifts the balance of generation of one-carbon units into the mitochondrion. (+info)
Nitrite reductase gene enrichment improves assimilation of NO(2) in Arabidopsis. (6/33)Transgenic plants of Arabidopsis bearing the spinach (Spinacia oleracea) nitrite reductase (NiR, EC 18.104.22.168) gene that catalyzes the six-electron reduction of nitrite to ammonium in the second step of the nitrate assimilation pathway were produced by use of the cauliflower mosaic virus 35S promoter and nopaline synthase terminator. Integration of the gene was confirmed by a genomic polymerase chain reaction (PCR) and Southern-blot analysis; its expression by a reverse transcriptase-PCR and two-dimensional polyacrylamide gel electrophoresis western-blot analysis; total (spinach + Arabidopsis) NiR mRNA content by a competitive reverse transcriptase-PCR; localization of NiR activity (NiRA) in the chloroplast by fractionation analysis; and NO(2) assimilation by analysis of the reduced nitrogen derived from NO(2) (NO(2)-RN). Twelve independent transgenic plant lines were characterized in depth. Three positive correlations were found for NiR gene expression; between the total NiR mRNA and total NiR protein contents (r = 0.74), between the total NiR protein and NiRA (r = 0.71), and between NiRA and NO(2)-RN (r = 0.65). Of these twelve lines, four had significantly higher NiRA than the wild-type control (P < 0.01), and three had significantly higher NO(2)-RN (P < 0.01). Each of the latter three had one to two copies of spinach NiR cDNA per haploid genome. The NiR flux control coefficient for NO(2) assimilation was estimated to be about 0.4. A similar value was obtained for an NiR antisense tobacco (Nicotiana tabacum cv Xanthi XHFD8). The flux control coefficients of nitrate reductase and glutamine synthetase were much smaller than this value. Together, these findings indicate that NiR is a controlling enzyme in NO(2) assimilation by plants. (+info)
Effects of breed, parity, and folic Acid supplement on the expression of folate metabolism genes in endometrial and embryonic tissues from sows in early pregnancy. (7/33)Folic acid and glycine are factors of great importance in early gestation. In sows, folic acid supplement can increase litter size through a decrease in embryonic mortality, while glycine, the most abundant amino acid in the sow oviduct, uterine, and allantoic fluids, is reported to act as an organic osmoregulator. In this study, we report the characterization of cytoplasmic serine hydroxymethyltransferase (cSHMT), T-protein, and vT-protein (variant T-protein) mRNA expression levels in endometrial and embryonic tissues in gestating sows on Day 25 of gestation according to the breed, parity, and folic acid + glycine supplementation. Expression levels of cSHMT, T-protein, and vT-protein mRNA in endometrial and embryonic tissues were performed using semiquantitative reverse transcription-polymerase chain reaction. We also report, for the first time, an alternative splicing event in the porcine T-protein gene. Results showed that a T-protein splice variant, vT-protein, is present in all the tested sow populations. Further characterizations revealed that this T-protein splice variant contains a coding intron that can adopt a secondary structure. Results demonstrated that cSHMT mRNA expression levels were significantly higher in sows receiving the folic acid + glycine supplementation, independently of the breed or parity and in both endometrial and embryonic tissues. Upon receiving the same treatment, the vT-protein and T-protein mRNA expression levels were significantly reduced in the endometrial tissue of Yorkshire-Landrace sows only. These results indicate that modulation of specific gene expression levels in endometrial and embryonic tissues of sows in early gestation could be one of the mechanism involved with the role of folic acid on improving swine reproduction traits.

Probing the H-protein-induced conformational change and the function of the N-terminal region of Escherichia coli T-protein of the glycine cleavage system by limited proteolysis. (8/33)T-protein, a component of the glycine cleavage system, catalyzes a tetrahydrofolate-dependent reaction. Previously, we reported a conformational change of Escherichia coli T-protein upon interacting with E. coli H-protein (EH), showing an important role for the N-terminal region of the T-protein in the interaction. To further investigate the T-protein catalysis, the wild type (ET) and mutants were subjected to limited proteolysis. ET was favorably cleaved at Lys(81), Lys(154), Lys(288), and Lys(360) by lysylendopeptidase and the cleavages at Lys(81) and Lys(288) were strongly prevented by EH. Although ET was highly resistant to trypsinolysis, the mutant with an N-terminal 7-residue deletion (ETDelta7) was quite susceptible and instantly cleaved at Arg(16) accompanied by the rapid degradation of the resulting C-terminal fragment, indicating that the cleavage at Arg(16) is the trigger for the C-terminal fragmentation. EH showed no protection from the N-terminal cleavage, although substantial protection from the C-terminal fragmentation was observed. The replacement of Leu(6) of ET with alanine resulted in a similar sensitivity to trypsin as ETDelta7. These results suggest that the N-terminal region of ET functions as a molecular "hasp" to hold ET in the compact form required for the proper association with EH. Leu(6) seems to play a central role in the hasp function. Interestingly, Lys(360) of ET was susceptible to proteolysis even after the stabilization of the entire molecule of ET by EH, indicating its location at the surface of the ET-EH complex. Together with the buried position of Lys(81) in the complex and previous results on folate binding sites, these results suggest the formation of a folate-binding cavity via the interaction of ET with EH. The polyglutamyl tail of the folate substrate may be inserted into the bosom of the cavity leaving the pteridine ring near the entrance of the cavity in the context of the catalytic reaction. (+info)

Crystal structure of DMGO provides a prototype for a new tetrahydrofolate-binding fold | Biochemical Society Transactions
The crystal structure of DMGO (dimethylglycine oxidase) from Arthrobacter globiformis in complex with folate compounds has revealed a novel THF (tetrahydrofolate)-binding fold [Leys, Basran and Scrutton (2003) EMBO J. 22, 4038-4048]. This fold is widespread among folate-binding proteins. The crystal structures of aminomethyltransferase (T-protein), YgfZ and TrmE all reveal similar THF-binding folds despite little similarity in sequence or function. The THF-binding site is highly specific for reduced folate compounds and most members of this fold family enhance the nucleophilic character of the THF N10 position.. ...

Glycine cleavage system - Wikipedia
This reaction, and by extension the glycine cleavage system, is required for photorespiration in C3 plants. The glycine cleavage system takes glycine, which is created from an unwanted byproduct of the Calvin cycle, and converts it to serine which can reenter the cycle. The ammonia generated by the glycine cleavage system, is assimilated by the Glutamine synthetase-Glutamine oxoglutarate aminotransferase cycle but costs the cell one ATP and one NADPH. The upside is that one CO2 is produced for every two O2 that are mistakenly taken up by the cell, generating some value in an otherwise energy depleting cycle. Together the proteins involved in these reactions comprise about half the proteins in mitochondria from spinach and pea leaves. The glycine cleavage system is constantly present in the leaves of plants, but in small amounts until they are exposed to light. During peak photosynthesis, the concentration of the glycine cleavage system increases ten-fold. In the anaerobic bacteria, ...
Variant non ketotic hyperglycinemia is caused by mutations in |i|LIAS|/i|, |i|BOLA3|/i| and the novel gene |i|GLRX5|/i| -...
Patients with nonketotic hyperglycinemia and deficient glycine cleavage enzyme activity, but without mutations in AMT, GLDC or GCSH, the genes encoding its constituent proteins, constitute a clinical group which we call variant nonketotic hyperglycinemia. We hypothesize that in some patients the aetiology involves genetic mutations that result in a deficiency of the cofactor lipoate, and sequenced genes involved in lipoate synthesis and iron-sulphur cluster biogenesis. Of 11 individuals identified with variant nonketotic hyperglycinemia, we were able to determine the genetic aetiology in eight patients and delineate the clinical and biochemical phenotypes. Mutations were identified in the genes for lipoate synthase (LIAS), BolA type 3 (BOLA3), and a novel gene glutaredoxin 5 (GLRX5). Patients with GLRX5-associated variant nonketotic hyperglycinemia had normal development with childhood-onset spastic paraplegia, spinal lesion, and optic atrophy. Clinical features of BOLA3-associated variant ...

Promoter Characterization and Constitutive Expression of the Escherichia coli gcvR Gene | Journal of Bacteriology
The Escherichia coliglycine cleavage enzyme system catalyzes the cleavage of glycine into carbon dioxide, ammonia, and 5,10-methylenetetrahydrofolate (9). Glycine is required for both protein and purine biosynthesis, while 5,10-methylenetetrahydrofolate serves as a one-carbon donor in the biosynthesis of purines, methionine, thymine, and numerous methylated products (15). Three components of the glycine cleavage enzyme system, the GcvT, GcvH, and GcvP proteins, are encoded by the gcv operon (17). Induced by glycine (13, 17, 28) and repressed by purines (8, 27), it appears that expression of the gcv operon is regulated in order to balance cellular requirements for glycine and one-carbon units.. Currently, four proteins, the leucine-responsive regulatory protein (Lrp), the purine repressor protein (PurR), the glycine cleavage activator protein (GcvA), and the glycine cleavage repressor protein (GcvR), have been shown to be involved in regulating expression of thegcv operon. Lrp is a global ...

DMOZ - Health: Conditions and Diseases: Nutritional and Metabolic Disorders: Inherited: Nonketotic Hyperglycinemia
Nonketotic hyperglycinemia is an inborn error of glycine degradation pathway presenting during the first days, even hours, of the newborn and causing severe brain damage and often early death. Glycine acts as neurotransmitter and its increased concentration due to deficient degradation has brain damaging effect. NKH does not affect the intrauterine development but after normal delivery the disease presents during the first days of life - 66 percent of cases were symptomatic before 48 hrs of life in one large series. Patients develop lethargy and profound hypotonia and refuse to feed. Wandering eye movements and intermittent ophthalmoplegia are frequent. As the encephalopathy progresses to coma, the infants develop frequent sequential myoclonic jerks, apneic episodes and hiccups. Most patients do not survive this stage without assisted ventilation. Even with assisted ventilation about 30 percent of patients die during the neonatal period. The surviving infants usually regain spontaneous respiration by 3
Light-dependent and tissue-specific expression of the H-protein of the glycine decarboxylase complex | [email protected]
Glycine decarboxylase is a mitochondrial enzyme complex, which is the site of photorespiratory CO2 and NH3 release. Although the proteins that constitute the complex are located within the mitochondria, because of their intimate association with photosynthesis their expression is controlled by light. Comparisons of the kinetics of mRNA accumulation between the small subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase and the H-protein of glycine decarboxylase during the greening of etiolated Arabidopsis thaliana suggest that their expression is controlled in parallel. A genomic clone for the H-protein (gdcH) was isolated from Arabidopsis and sequenced. The upstream region from -856 to +62 was fused to the β-glucuronidase (GUS) reporter gene, and this construct was transformed into tobacco. This 5′ upstream regulatory region appears to control GUS expression in a manner very similar to that of the endogenous H-protein gene. Constructs with deletions in the 5′ upstream region were ...
One carbon enzyme systems Serine hydroxymethyltransferase (SHMT) and Glycine cleavage complex (GCV) | LAMP
Serine hydroxymethyltransferase (SHMT) is the enzyme which catalyses the conversion of serine to glycine and vice versa. This enzyme provides the capability of de novo glycine biosynthesis to Apicomplexa. In addition, it is important to folate metabolism as this glycine biosynthesis also leads to synthesis of 5,10-methylene-tetrahydrofolate, an essential substrate of thymidylate synthase enzyme (catalyses generation of thymidine nucleotides). The characterisation, expression and kinetic studies with P. falciparum SHMT demonstrates that it is a regulatory step of thymidylate cycle and serves a good drug target . Glycine cleavage system is a system of four proteins and they are P-protein, T-protein, L-protein and H-protein. When glycine is in excess, the first three proteins catalyse three enzymatic steps and H-protein acts as an aminomethyl-group carrier. This set of reactions generates carbon dioxide, ammonia and 5,10-methylene-THF utilising glycine and tetrahydrofolate as substrates. In ...

Hyperglycinemia - Wikipedia
Hyperglycinemia refers to a metabolic condition where glycine is elevated in the blood. \ A few of the symptoms relating to the condition include spasticity, seizures, involuntary muscle contractions, hiccups, poor feeding, lethargy, intellectual disabilities, apnea, listlessness, failure to thrive, reduced muscle tone, and many more. Each of these symptoms pertains to hyperglycinemia as a whole and its two types. This condition has many misdiagnosises. Some of the related conditions that get misdiagnosis when patients with hyperglycinemia are evaluated are: hypertension, type 1 and 2 diabetes, high cholesterol, depression, cancer, and heart disease. Propionic acidemia, also known as ketotic glycinemia Glycine encephalopathy, also known as non-ketotic hyperglycinemia Each specific type has its own set of symptoms. Hyperclycinemia was first found in 1957, but it wasnt diagnosed until 1961 at Johns Hopkins Hospital in Baltimore, Maryland. Eric, the little boy who led to the discover of the ...
Neurobiology of a Mutation in Glycine Metabolism in Psychotic Disorders - Tabular View - ClinicalTrials.gov
Multiple rare structural variants of relatively recent evolutionary origin are recognized as important risk factors for schizophrenia (SZ) and other neurodevelopmental disorders (e.g., autism spectrum disorders, mental retardation, epilepsy) with odds ratios as high as 7-30 (Sebat et al. 2009; Malhotra et al. 2011; Heinzen et al. 2010; Weiss et al. 2008; McCarthy et al. 2009). We have found a de novo structural rearrangement on chromosome 9p24.1 in two psychotic patients. One of the genes in this region is the gene encoding glycine decarboxylase (GLDC), which affects brain glycine metabolism. GLDC encodes the glycine decarboxylase or glycine cleavage system P-protein, which is involved in degradation of glycine in glia cells. Carriers of the GLDC triplication would be expected to have low levels of brain Gly, resulting in NMDA receptor-mediated hypofunction, which has been strongly implicated in the pathophysiology of schizophrenia (Olney & Farber, 1995; Coyle, 2006; Javitt, 2007)..

Glycine decarboxylase in Rhodopseudomonas spheroides and in rat liver mitochondria | Biochemical Journal
1. Glycine decarboxylase and glycine-bicarbonate exchange activities were detected in extracts of Rhodopseudomonas spheroides and in rat liver mitochondria and their properties were studied. 2. The glycine decarboxylase activity from both sources is stimulated when glyoxylate is added to the assay system. 3. Several proteins participate in these reactions and a heat-stable low-molecular-weight protein was purified from both sources. 4. These enzyme activities increase markedly when R. spheroides is grown in the presence of glycine, glyoxylate, glycollate, oxalate or serine. 5. All the enzymes required to catalyse the conversion of glycine into acetyl-CoA via serine and pyruvate were detected in extracts of R. spheroides; of these glycine decarboxylase has the lowest activity. 6. The increase in the activity of glycine decarboxylase on illumination of R. spheroides in a medium containing glycine, and the greater increase when ATP is also present in the medium, probably accounts for the increased ...

TY - JOUR. T1 - Glycine decarboxylase is a transcriptional target of MYCN required for neuroblastoma cell proliferation and tumorigenicity. AU - Alptekin, Ahmet. AU - Ye, Bingwei. AU - Yu, Yajie. AU - Poole, Candace J.. AU - van Riggelen, Jan. AU - Zha, Yunhong. AU - Ding, Han Fei. N1 - Funding Information: This work was supported by an NIH grant (R01 CA190429). PY - 2019/12/12. Y1 - 2019/12/12. N2 - Genomic amplification of the oncogene MYCN is a major driver in the development of high-risk neuroblastoma, a pediatric cancer with poor prognosis. Given the challenge in targeting MYCN directly for therapy, we sought to identify MYCN-dependent metabolic vulnerabilities that can be targeted therapeutically. Here, we report that the gene encoding glycine decarboxylase (GLDC), which catalyzes the first and rate-limiting step in glycine breakdown with the production of the one-carbon unit 5,10-methylene-tetrahydrofolate, is a direct transcriptional target of MYCN. As a result, GLDC expression is ...

A biochemical analysis of the interaction of victorin and oats
Victoria blight of oats is caused by the fungus Cochhobolus victoriae. This fungus is pathogenic due to its ability to produce the host-selective toxin victorin. Previously, a 100-kD protein that binds victorin in vivo only in susceptible genotypes was identified as the P protein of the glycine decarboxylase complex (GDC). Victorin is a potent in vivo inhibitor of GDC. Leaf slices pretreated with victorin displayed an effective Victorin inhibited the concentration for 50% inhibition (EC₅₀) of 81 μM for GDA. glycine-bicarbonate exchange reaction in vitro with an EC₅₀ of 23 μM. We also identified a 15-kD mitochondrial protein in susceptible and resistant genotypes that hound victorin. Amino acid sequence analysis indicated this protein is the H protein component of the GDC. Thus, victorin specifically binds to two components of the GDC. Victorin had no detectable effect on GDC in isolated mitochondria, apparently due to the inability of isolated mitochondria to import victorin. The ...

m6A and m4C methyltransferases are found primarily in prokaryotes (although recent evidence has suggested that m6A is abundant in eukaryotes). m5C methyltransfereases are found in some lower eukaryotes, in most higher plants, and in animals beginning with the echinoderms. The m6A methyltransferases (N-6 adenine-specific DNA methylase) (A-Mtase) are enzymes that specifically methylate the amino group at the C-6 position of adenines in DNA. They are found in the three existing types of bacterial restriction-modification systems (in type I system the A-Mtase is the product of the hsdM gene, and in type III it is the product of the mod gene). These enzymes are responsible for the methylation of specific DNA sequences in order to prevent the host from digesting its own genome via its restriction enzymes. These methylases have the same sequence specificity as their corresponding restriction enzymes. These enzymes contain a conserved motif Asp/Asn-Pro-Pro-Tyr/Phe in their N-terminal section, this ...
Measurement of TPMT activity is encouraged prior to commencing the treatment of patients with thiopurine drugs such as azathioprine, 6-mercaptopurine and 6-thioguanine. Patients with low activity (10% prevalence) or especially absent activity (prevalence 0.3%) are at a heightened risk of drug-induced bone marrow toxicity due to accumulation of the unmetabolised drug. Reuther et al. found that about 5% of all thiopurine therapies will fail due to toxicity. This intolerant group could be anticipated by routine measurement of TPMT activity. There appears to be a great deal of variation in TPMT mutation, with ethnic differences in mutation types accounting for variable responses to 6MP. Genetic variants of TPMT have also been associated with cisplatin-induced ototoxicity in children. TPMT is now listed as a pharmacogenomic biomarker for adverse drug reactions to cisplatin by the FDA. ...
