tRNA synthetase mutants of Escherichia coli K-12 are resistant to the gyrase inhibitor novobiocin. (1/81)

In previous studies we demonstrated that mutations in the genes cysB, cysE, and cls (nov) affect resistance of Escherichia coli to novobiocin (J. Rakonjac, M. Milic, and D. J. Savic, Mol. Gen. Genet. 228:307-311, 1991; R. Ivanisevic, M. Milic, D. Ajdic, J. Rakonjac, and D. J. Savic, J. Bacteriol. 177:1766-1771, 1995). In this work we expand this list with mutations in rpoN (the gene for RNA polymerase subunit sigma54) and the tRNA synthetase genes alaS, argS, ileS, and leuS. Similarly to resistance to the penicillin antibiotic mecillinam, resistance to novobiocin of tRNA synthetase mutants appears to depend upon the RelA-mediated stringent response. However, at this point the overlapping pathways of mecillinam and novobiocin resistance diverge. Under conditions of stringent response induction, either by the presence of tRNA synthetase mutations or by constitutive production of RelA protein, inactivation of the cls gene diminishes resistance to novobiocin but not to mecillinam.  (+info)

SmpB, a unique RNA-binding protein essential for the peptide-tagging activity of SsrA (tmRNA). (2/81)

In bacteria, SsrA RNA recognizes ribosomes stalled on defective messages and acts as a tRNA and mRNA to mediate the addition of a short peptide tag to the C-terminus of the partially synthesized nascent polypeptide chain. The SsrA-tagged protein is then degraded by C-terminal-specific proteases. SmpB, a unique RNA-binding protein that is conserved throughout the bacterial kingdom, is shown here to be an essential component of the SsrA quality-control system. Deletion of the smpB gene in Escherichia coli results in the same phenotypes observed in ssrA-defective cells, including a variety of phage development defects and the failure to tag proteins translated from defective mRNAs. Purified SmpB binds specifically and with high affinity to SsrA RNA and is required for stable association of SsrA with ribosomes in vivo. Formation of an SmpB-SsrA complex appears to be critical in mediating SsrA activity after aminoacylation with alanine but prior to the transpeptidation reaction that couples this alanine to the nascent chain. SsrA RNA is present at wild-type levels in the smpB mutant arguing against a model of SsrA action that involves direct competition for transcription factors.  (+info)

Single-nucleotide polymorphisms can cause different structural folds of mRNA. (3/81)

Single-nucleotide polymorphisms (SNPs) are the most common type of genetic variation in man. Genes containing one or more SNPs can give rise to two or more allelic forms of mRNAs. These mRNA variants may possess different biological functions as a result of differences in primary or higher order structures that interact with other cellular components. Here we report the observation of marked differences in mRNA secondary structure associated with SNPs in the coding regions of two human mRNAs: alanyl tRNA synthetase and replication protein A, 70-kDa subunit (RPA70). Enzymatic probing of SNP-containing allelic fragments of the mRNAs revealed pronounced allelic differences in cleavage pattern at sites 14 or 18 nt away from the SNP, suggesting that a single-nucleotide variation can give rise to different mRNA folds. By using phosphorothioate oligodeoxyribonucleotides complementary to the region of different allelic structures in the RPA70 mRNA, but not extending to the SNP itself, we find that the SNP exerts an allele-specific effect on the accessibility of its flanking site in the endogenous human RPA70 mRNA. This further supports the allele-specific structural features identified by enzymatic probing. These results demonstrate the contribution of common genetic variation to structural diversity of mRNA and suggest a broader role than previously thought for the effects of SNPs on mRNA structure and, ultimately, biological function.  (+info)

CDC64 encodes cytoplasmic alanyl-tRNA synthetase, Ala1p, of Saccharomyces cerevisiae. (4/81)

The cdc64-1 mutation causes G(1) arrest in Saccharomyces cerevisiae corresponding to a type II Start phenotype. We report that CDC64 encodes Ala1p, an alanyl-tRNA synthetase. Thus, cdc64-1 might affect charging of tRNA(Ala) and thereby initiation of cell division.  (+info)

Identification of discriminator base atomic groups that modulate the alanine aminoacylation reaction. (5/81)

Specific aminoacylation of tRNAs involves activation of an amino acid with ATP followed by amino acid transfer to the tRNA. Previous work showed that the transfer of alanine from Escherichia coli alanyl-tRNA synthetase to a cognate RNA minihelix involves a transition state sensitive to changes in the tRNA acceptor stem. Specifically, the "discriminator" base at position 73 of minihelix(Ala) is a critical determinant of the transfer step of aminoacylation. This single-stranded nucleotide has previously been shown by solution NMR to be stacked predominantly onto G(1) of the first base pair of the alanine acceptor stem helix. In this work, RNA duplex(Ala) variants were prepared to investigate the role of specific discriminator base atomic groups in aminoacylation catalytic efficiency. Results indicate that the purine structure appears to be important for stabilization of the transition state and that major groove elements are more critical than those located in the minor groove. This result is in accordance with the predicted orientation of a class II synthetase at the end of the acceptor helix. In particular, substitution of the exocyclic amino group of A(73) with a keto-oxygen resulted in negative discrimination at this site. Taken together, these new results are consistent with the involvement of major groove atomic groups of the discriminator base in the formation of the transition state for the amino acid transfer step.  (+info)

Expression of Arabidopsis thaliana mitochondrial alanyl-tRNA synthetase is not sufficient to trigger mitochondrial import of tRNAAla in yeast. (6/81)

It has often been suggested that precursors to mitochondrial aminoacyl-tRNA synthetases are likely carriers for mitochondrial import of tRNAs in those organisms where this process occurs. In plants, it has been shown that mutation of U(70) to C(70) in Arabidopsis thaliana tRNA(Ala)(UGC) blocks aminoacylation and also prevents import of the tRNA into mitochondria. This suggests that interaction of tRNA(Ala) with alanyl-tRNA synthetase (AlaRS) is necessary for import to occur. To test whether this interaction is sufficient to drive import, we co-expressed A. thaliana tRNA(Ala)(UGC) and the precursor to the A. thaliana mitochondrial AlaRS in Saccharomyces cerevisiae. The A. thaliana enzyme and its cognate tRNA were correctly expressed in yeast in vivo. However, although the plant AlaRS was efficiently imported into mitochondria in the transformed strains, we found no evidence for import of the A. thaliana tRNA(Ala) nor of the endogenous cytosolic tRNA(Ala) isoacceptors. We conclude that at least one other factor besides the mitochondrial AlaRS precursor must be involved in mitochondrial import of tRNA(Ala) in plants.  (+info)

Importance of discriminator base stacking interactions: molecular dynamics analysis of A73 microhelix(Ala) variants. (7/81)

Transfer of alanine from Escherichia coli alanyl-tRNA synthetase (AlaRS) to RNA minihelices that mimic the amino acid acceptor stem of tRNA(Ala) has been shown, by analysis of variant minihelix aminoacylation activities, to involve a transition state sensitive to changes in the 'discriminator' base at position 73. Solution NMR has indicated that this single-stranded nucleotide is predominantly stacked onto G1 of the first base pair of the alanine acceptor stem helix. We report the activity of a new variant with the adenine at position 73 substituted by its non-polar isostere 4-methylindole (M). Despite lacking N7, this analog is well tolerated by AlaRS. Molecular dynamics (MD) simulations show that the M substitution improves position 73 base stacking over G1, as measured by a stacking lifetime analysis. Additional MD simulations of wild-type microhelix(Ala) and six variants reveal a positive correlation between N73 base stacking propensity over G1 and aminoacylation activity. For the two DeltaN7 variants simulated we found that the propensity to stack over G1 was similar to the analogous variants that contain N7 and we conclude that the decrease in aminoacylation efficiency observed upon deletion of N7 is likely due to loss of a direct stabilizing interaction with the synthetase.  (+info)

Origin of mitochondria in relation to evolutionary history of eukaryotic alanyl-tRNA synthetase. (8/81)

The origin of the eukaryotic cell remains an unsolved question. Numerous experimental and phylogenetic observations support the symbiotic origin of the modern eukaryotic cell, with its nucleus and (typically) mitochondria. Incorporation of mitochondria has been proposed to precede development of the nucleus, but it is still unclear whether mitochondria were initially part of basal eukaryotes. Data on alanyl-tRNA synthetase from an early eukaryote and other sources are presented and analyzed here. These data are consistent with the notion that mitochondrial genesis did not significantly precede nucleus formation. Moreover, the data raise the possibility that diplomonads are primary amitochondriates that radiated from the eukaryotic lineage before mitochondria became fully integrated as a cellular organelle.  (+info)

Alanine (L-Alanine) is an α-amino acid that is used for protein biosynthesis. Approximately 8% of human proteins have alanine in their structures. The reductive lamination of pyruvate is effected by alanine transaminase. L-Alanine can be converted to pyruvic acid by alanine aminotransferase 1 reversibly coupled with interconversion of oxoglutaric acid and L-glutamic acid. L-Alanine can also be produced by alanine-glyoxylate transaminase with coupled interconversion of glyoxylate and glycine. L-Alanine will be coupled with alanyl tRNA by alanyl-tRNA synthetase to perform protein biosynthesis. Alanine can also be used to provide energy under fasting conditions. There are two pathways that can facilitate this: (1) alanine is converted to pyruvate to synthesize glucose via the gluconeogenesis pathway in liver tissue or (2) alanine converted into pyruvate moves into the TCA cycle to be oxidized in other tissues ...

The mitochondrial aminoacyl-tRNA synthetase proteins (mt-aaRSs) are a group of nuclear-encoded enzymes that facilitate conjugation of each of the 20 amino acids to its cognate tRNA molecule. Mitochondrial diseases are a large, clinically heterogeneous group of disorders with diverse etiologies, ages of onset, and involved organ systems. Diseases related to mt-aaRS mutations are associated with specific syndromes that affect the central nervous system and produce highly characteristic MRI patterns, prototypically the DARS2, EARS, and AARS2 leukodystrophies, which are caused by mutations in mitochondrial aspartyl-tRNA synthetase, mitochondria glutamate tRNA synthetase, and mitochondrial alanyl-tRNA synthetase, respectively. The disease patterns emerging for these leukodystrophies are distinct in terms of the age of onset, nature of disease progression, and predominance of involved white matter tracts. In DARS2 and EARS2 disorders, earlier disease onset is typically correlated with more significant brain

British Library EThOS: Glycyl-tRNA synthetase mutations in neurological disease : mechanisms and modelsBritish Library EThOS: Glycyl-tRNA synthetase mutations in neurological disease : mechanisms and models
Charcot-Marie- Tooth disease type 2D (CMT2D) is a dominantly inherited axonal neuropathy caused by missense mutations in the glycyl-tRN A synthetase gene (CARS). Dominant mutations in tyrosyl-tRNA synthetase and alanyl-tRNA synthetase also cause CMT, suggesting a shared mechanism for all three diseases. The goal of this thesis was to investigate possible mechanisms and narrow the potential ways that mutations in CARS could lead to axon loss. GARS mutations are distributed throughout the protein in multiple functional domains. The localization, dimerization, and degradation of GARS were examined as in vitro measures of protein function. Dimer function was preserved in most mutants. Similarly, no differences in wild-type and mutant localization or degradation were seen. In vitro experiments did not show evidence of a loss of function in most GARS mutants. Progress has also been made towards the development of a Drosophila model of CMT2D. Overexpression of mutant Aats-gly, the Drosophila ortholog ...

An aminoacyl-tRNA editing enzyme that deacylates mischarged D-aminoacyl-tRNAs, has no observable editing activity on tRNAs charged with cognate L-amino acid (PubMed:10383414, PubMed:4292198, PubMed:10918062, PubMed:24302572, PubMed:27224426). Edits mischarged glycyl-tRNA(Ala) more efficiently than AlaRS (PubMed:28362257). Acts via tRNA-based rather than protein-based catalysis (PubMed:24302572, PubMed:27224426, PubMed:28362257). Rejects correctly charged L-amino acid-tRNAs from its binding site rather than specifically recognizing incorrectly charged D-amino acid-tRNAs (PubMed:27224426). Hydrolyzes correctly charged, achiral, glycyl-tRNA(Gly); GTP-bound EF-Tu (tested with T.thermophilus EF-Tu AC Q5SHN6) protects charged glycyl-tRNA(Gly) from hydrolysis, while increasing Dtd levels or inactivating EF-Tu decreases protection (PubMed:27224426).

Despite a large agreement between ribosomal RNA and concatenated protein phylogenies, the phylogenetic tree of the bacterial domain remains uncertain in its deepest nodes. For instance, the position of the hyperthermophilic Aquificales is debated, as their commonly observed position close to Thermotogales may proceed from horizontal gene transfers, long branch attraction or compositional biases, and may not represent vertical descent. Indeed, another view, based on the analysis of rare genomic changes, places Aquificales close to epsilon-Proteobacteria. To get a whole genome view of Aquifex relationships, all trees containing sequences from Aquifex in the HOGENOM database were surveyed. This study revealed that Aquifex is most often found as a neighbour to Thermotogales. Moreover, informational genes, which appeared to be less often transferred to the Aquifex lineage than non-informational genes, most often placed Aquificales close to Thermotogales. To ensure these results did not come from long branch

Glycyl-tRNA synthetase (GARS) is one of 37 nuclear encoded amino acyl tRNA synthetases that function to attach amino acids onto their respective tRNA for protein translation.44 Since the discovery of GARS as a cause of dHMNV and CMT2D, mutations in three other amino acyl tRNAs have been identified as causes of intermediate CMT (DI-CMTC) (YARS, tyrosyl-tRNA synthetase),45 CMT2N (AARS, alanyl-tRNA synthetase)46 and autosomal recessive CMT2 (RI-CMTB) (KARS, lysyl-tRNA synthetase).47. In 2003, four different GARS mutations were discovered in five families with upper-limb predominant distal motor neuropathy (dHMNV or CMT2D).10 Six additional familial and sporadic cases of dHMN owing to GARS mutations have been reported.48-51 In an extended phenotype/genotype study of the original five families, 75% of affected family members presented in the second decade of life, with the majority functioning independently 40 years after disease onset.52 In one patient, weakness began in the lower limbs, ...

Aminoacyl tRNA Synthetase - Proteopedia, life in 3DAminoacyl tRNA Synthetase - Proteopedia, life in 3D
Aminoacyl tRNA synthetase (aaRS) or tRNA ligase catalyzes the esterification of a specific amino acid to its cognate tRNA to form an aminoacyl-tRNA. The amino acid is transferred by the ribosome from the aminoacylated-tRNA onto a growing polypeptide chain. Class I of aaRS is a monomer or dimer, it has 2 highly conserved sequence motifs and it aminoacylates at the 2-OH of an adenosine nucleotide. Class II of aaRS is a dimer or tetramer, it has 3 highly conserved sequence motifs and it aminoacylates at the 3-OH of an adenosine nucleotide. CP1 domain of RS edits a mischarged aa-tRNA. Some of the crystal structures are complexes of the RS with their reactant analog: amino acid-sulfamoyl adenine (aa-SA).[1]. ...

The genetic code is brought into action by 20 aminoacyl-tRNA synthetases. These enzymes are evenly divided into two classes (I and II) that recognize tRNAs from the minor and major groove sides of the acceptor stem, respectively. We have reported recently that: (1) ribozymic precursors of the synthetases seem to have used the same two sterically mirror modes of tRNA recognition, (2) having these two modes might have helped in preventing erroneous aminoacylation of ancestral tRNAs with complementary anticodons, yet (3) the risk of confusion for the presumably earliest pairs of complementarily encoded amino acids had little to do with anticodons. Accordingly, in this communication we focus on the acceptor stem. Our main result is the emergence of a palindrome structure for the acceptor stems common ancestor, reconstructed from the phylogenetic trees of Bacteria, Archaea and Eukarya. In parallel, for pairs of ancestral tRNAs with complementary anticodons, we present updated evidence of concerted

QARS mutations, tRNA, and neurodegeneration with migrating seizures | Beyond the Ion ChannelQARS mutations, tRNA, and neurodegeneration with migrating seizures | Beyond the Ion Channel
QARS, DARS, KARS. The current publication by Zhang and collaborators give us an interesting refresher course on basic molecular biology, particularly a section of the cellular machinery that I didnt believe to be relevant to human genetic epilepsies - tRNAs. In humans the amino acids are attached to the tRNAs through 37 different forms of tRNA synthetases, 17 of them only present in mitochondria. The names of the tRNA synthetases is derived from the specific amino acid symbol, followed by the suffix -ARS. Amongst the various tRNA synthetases implicated in human disease, two disease-related aaRS occur in a functional complex with QARS, the multisynthetase complex. These two aaRS are KARS and DARS. The KARS gene coding for the lysine tRNA synthetase has been found to be mutated in a particular form of Charcot-Marie-Tooth disease and, separately from this, nonsyndromic hearing loss. Mutations in the DARS gene coding for the asparate tRNA synthetase cause an inherited white matter disorder with leg ...

Creatine kinaseCreatine kinase
The mitochondrial creatine kinase (CKm) is present in the mitochondrial intermembrane space, where it regenerates phosphocreatine (PCr) from mitochondrially generated ATP and creatine (Cr) imported from the cytosol. Apart from the two mitochondrial CK isoenzyme forms, that is, ubiquitous mtCK (present in non-muscle tissues) and sarcomeric mtCK (present in sarcomeric muscle), there are three cytosolic CK isoforms present in the cytosol, depending on the tissue. Whereas MM-CK is expressed in sarcomeric muscle, that is, skeletal and cardiac muscle, MB-CK is expressed in cardiac muscle, and BB-CK is expressed in smooth muscle and in most non-muscle tissues. Mitochondrial mtCK and cytosolic CK are connected in a so-called PCr/Cr-shuttle or circuit. PCr generated by mtCK in mitochondria is shuttled to cytosolic CK that is coupled to ATP-dependent processes, e.g. ATPases, such as acto-myosin ATPase and calcium ATPase involved in muscle contraction, and sodium/potassium ATPase involved in sodium ...
