In this study, we demonstrate the presence of a transacetylase activity in human plasma low-density lipoprotein (LDL) that transfers short-chain fatty acids from platelet-activating factor (PAF) and its close ether- and ester-linked analogues to ether/ester-linked lysophospholipids (lyso-PL). We show evidence that both PAF acetylhydrolase (PAF-AH) and transacetylase activities are inhibited to the same extent by serine esterase inhibitors, are resistant to heat treatment, and exhibit identical distributions in lipoprotein classes and in LDL subfractions. Additionally, the competitive inhibition of PAF-AH by lyso-PL, and the evidence that the recombinant PAF-AH also showed a similar transacetylase activity, suggest that PAF-AH is responsible for both activities. Using PAF as a donor molecule and lyso-PAF (1-O-alkyl-sn-glycero-3-phosphocholine) as an acceptor, the transacetylase activity showed typical allosteric kinetics, due to the positive co-operativity of the substrates, with apparent Vmax = ...

The enzyme 1-O-alkyl-2-lyso-sn-glycero-3-phosphocholine: acetyl-CoA acetyltransferase (EC 2.3.1.67) was purified from rat spleen approx. 1500-fold in 1.6% yield. The specific activity of the purified enzyme was 0.317 +/- 0.089 mumol/min per mg of protein (mean +/- S.D., n = 6). The Km for the substrate acetyl-CoA was 137 +/- 13 microM and the pH optimum was about 8. Incubation of the purified enzyme was 1-O-[3H]octadecyl-2-lyso-sn-glycero-3-phosphocholine followed by electrophoresis resulted in the incorporation of radioactivity into a protein of Mr 29,000. The enzyme was most active towards 1-O-alkyl-2-lyso-sn-glycero-3-phosphocholine as substrate, 1-palmitoyl-2-lyso-glycero-3-phosphocholine being a poor substrate. In addition, the enzyme preferred acetyl-CoA to palmitoyl-CoA or oleoyl-CoA as substrate.. ...

The cuticle covers the outer surface of the leaf and stem epidermis and is the interface between the plant and the atmosphere. It has pivotal functions for the plant, including limiting the diffusion of water and solutes while permitting a controlled release of volatiles. It provides protection from attack by herbivores and pathogens and helps the plants resist drought and frost. The brunt of plant VLCFA synthesis occurs in epidermal cells. At the level of the whole plant, the main function of VLCFAs in terms of carbon mass partitioned is their role as precursors for various components of the cuticle such as cutin, epicuticular waxes, and other waxes that are embedded in suberin and cutin layers (3).. However, VLCFAs are also essential components of waxes in the tryphine layer of the extracellular pollen coat (28). They are required for proper pollen-stigma signaling and fertilization (29). Furthermore, VLCFAs accumulate as storage lipids in the seed oil of some plants, in which they are ...

Abstract. Posttranslational modifications are responsible for tuning the function of microtubules. Most posttranslational modification sites are on the exterior of the microtubule where enzymes have relatively free access. Acetylation, however, occurs on the interior of the microtubule. This paper explores the possible mechanism by which the acetyltransferase enzyme αTAT1 is able to access this site. Citation. Courtney Coombes, Ami Yamamoto, Mark McClellan, Taylor A.

GCN5, a putative transcriptional adapter in humans and yeast, possesses histone acetyltransferase (HAT) activity which has been linked to GCN5s role in transcriptional activation in yeast. In this report, we demonstrate a functional interaction between human GCN5 (hGCN5) and the DNA-dependent protein kinase (DNA-PK) holoenzyme. Yeast two-hybrid screening detected an interaction between the bromodomain of hGCN5 and the p70 subunit of the human Ku heterodimer (p70-p80), which is the DNA-binding component of DNA-PK. Interaction between intact hGCN5 and Ku70 was shown biochemically using recombinant proteins and by coimmunoprecipitation of endogenous proteins following chromatography of HeLa nuclear extracts. We demonstrate that the catalytic subunit of DNA-PK phosphorylates hGCN5 both in vivo and in vitro and, moreover, that the phosphorylation inhibits the HAT activity of hGCN5. These findings suggest a possible regulatory mechanism of HAT activity. ...

Atlantic salmon (Salmo salar) have been the focus of considerable research effort as a result of their widespread environmental and economic importance as a sporting and cultured species, write Greta Carmona-Antoñanzas, Douglas R Tocher, John B Taggart and Michael J Leaver. In addition, in common with all other salmonids, they possess a comparatively recently duplicated genome, believed to have arisen as a result of a relatively recent autotetraploidisation event between 25 and 100 mya. Whole-genome duplication (WGD) has been argued as a powerful evolutionary force creating new raw material for evolution to act upon, thus enabling the divergence and neo- or subfunctionalisation of duplicated loci promoting adaptation and speciation.. The imprints of three or four ancient duplications can be detected in vertebrate genomes, including a specific event early in teleost evolution and the recent one in salmonids. Esocids (members of the pike family) are regarded as having the closest extant ...

SAGA/TFTC is a histone acetyltransferase organic which has a second enzymatic activity due to the current presence GSK126 of a deubiquitination component (DUBm). of multiprotein coactivator complexes are structured into sophisticated systems to provide accurate and precise functioning from the RNA polymerase II (RNAP II) equipment. Furthermore different transcription levels are intimately linked to each other also to mRNP development and nuclear export. SAGA is normally a big multifunctional multisubunit coactivator complicated that possesses histone acetyltransferase and histone deubiquitination enzymatic actions and it is extremely conserved through the advancement of eukaryotes (1). The histone acetyltransferase module of SAGA consists of a Gcn5-catalytic subunit and works by checking the chromatin surroundings towards Rabbit polyclonal to AGAP. the binding of GSK126 extra transcription elements which leads to PIC formation (2-4).

Acetylation of the lysine residues in histones and other DNA-binding proteins plays a major role in regulation of eukaryotic gene expression. This process is controlled by histone acetyltransferases (HATs/KATs) found in multiprotein complexes that are recruited to chromatin by the scaffolding subunit transformation/transcription domain-associated protein (TRRAP). TRRAP is evolutionarily conserved and is among the top five genes intolerant to missense variation. Through an international collaboration, 17 distinct de novo or apparently de novo variants were identified in TRRAP in 24 individuals. A strong genotype-phenotype correlation was observed with two distinct clinical spectra. The first is a complex, multi-systemic syndrome associated with various malformations of the brain, heart, kidneys, and genitourinary system and characterized by a wide range of intellectual functioning; a number of affected individuals have intellectual disability (ID) and markedly impaired basic life functions.

Mechanisms of heritability of histone state are not well understood; however, much is known about the mechanism of heritability of DNA methylation state during cell division and differentiation. Heritability of methylation state depends on certain enzymes (such as DNMT1) that have a higher affinity for 5-methylcytosine than for cytosine. If this enzyme reaches a hemimethylated portion of DNA (where 5-methylcytosine is in only one of the two DNA strands) the enzyme will methylate the other half.. Although histone modifications occur throughout the entire sequence, the unstructured N-termini of histones (called histone tails) are particularly highly modified. These modifications include acetylation, methylation, ubiquitylation, phosphorylation, sumoylation, ribosylation and citrullination. Acetylation is the most highly studied of these modifications. For example, acetylation of the K14 and K9 lysines of the tail of histone H3 by histone acetyltransferase enzymes (HATs) is generally related to ...

The three classes of enzymes which inactivate aminoglycosides and lead to bacterial resistance are reviewed. DNA hybridization studies have shown that different genes can encode aminoglycoside-modifying enzymes with identical resistance profiles. Comparisons of the amino acid sequences of 49 aminoglycoside-modifying enzymes have revealed new insights into the evolution and relatedness of these proteins. A preliminary assessment of the amino acids which may be important in binding aminoglycosides was obtained from these data and from the results of mutational analysis of several of the genes encoding aminoglycoside-modifying enzymes. Recent studies have demonstrated that aminoglycoside resistance can emerge as a result of alterations in the regulation of normally quiescent cellular genes or as a result of acquiring genes which may have originated from aminoglycoside-producing organisms or from other resistant organisms. Dissemination of these genes is aided by a variety of genetic elements ...

Mier1 encodes a novel transcriptional regulator and was originally isolated as a fibroblast growth factor early response gene. Two major protein isoforms have been identified, MIER1α and β, which differ in their C-terminal sequence. Previously, we demonstrated that both isoforms recruit histone deacetylase 1 (HDAC1) to repress transcription. To further explore the role of MIER1 in chromatin remodeling, we investigated the functional interaction of MIER1 with the histone acetyltransferase (HAT), Creb-binding protein (CBP). Using GST pull-down assays, we demonstrate that MIER1 interacts with CBP and that this interaction involves the N-terminal half (amino acids 1-283) of MIER1, which includes the acidic activation and ELM2 domains and the C-terminal half (amino acids 1094-2441) of CBP, which includes the bromo-, HAT, C/H3 and glutamine-rich domains. Functional analysis, using HEK293 cells, shows that the CBP bound to MIER1 in vivo has no detectable HAT activity. Histone 4 peptide binding assays

The 70kDa ribosomal protein S6 kinases (S6K1 and S6K2) play important roles in the regulation of protein synthesis, cell growth and survival. S6Ks are activated in response to mitogen stimulation and nutrient sufficiency by the phosphorylation of conserved serine and threonine residues. Here we show for the first time, that in addition to phosphorylation, S6Ks are also targeted by lysine acetylation. Following mitogen stimulation, S6Ks interact with the p300 and p300/CBP-associated factor (PCAF) acetyltransferases. S6Ks can be acetylated by p300 and PCAF in vitro and S6K acetylation is detected in cells expressing p300. Furthermore, it appears that the acetylation sites targeted by p300 lie within the divergent C-terminal regulatory domains of both S6K1 and S6K2. Acetylation of S6K1 and 2 is increased upon the inhibition of class I/II histone deacetylases (HDACs) by trichostatin-A, while the enhancement of S6K1 acetylation by nicotinamide suggests the additional involvement of sirtuin ...

TRA1 is an essential gene in Saccharomyces cerevisiae that encodes a 437 kDa protein product. It is a member of a family of key signaling and regulatory molecules that contain a C-terminal phosphatidylinositol-3-kinase (PI3K) domain [1] and is a component of two multisubunit transcriptional regulatory complexes, the SAGA/SLIK and NuA4 complexes, which also contain the histone acetyltransferase enzymes, Gcn5 and Esa1, respectively [2-4]. Tra1 interacts directly with transcriptional activator proteins and is thought to be critical in recruitment of SAGA/SLIK and NuA4 to their target promoters [5-8].. Previously we identified mutations in the C-terminal PI3K domain of Tra1 that showed defects in transcriptional activation, sensitivity to ethanol and the cell wall destabilizing agent calcofluor white and resulted in shortened telomeres [9]. The pattern of changes neither fully mimicked those seen upon disruption of other SAGA/SLIK nor NuA4 components. For example, unlike strains with deletions of ...

Reversible acetylation of histone tails plays an important role in chromatin remodelling and regulation of gene activity. While modification by histone acetyltransferase (HAT) is usually linked to transcriptional activation, we provide here evidence for HAT function in several types of epigenetic repression. Chameau (Chm), a new Drosophila member of the MYST HAT family, dominantly suppresses position effect variegation (PEV), is required for the maintenance of Hox gene silencing by Polycomb group (PcG) proteins, and can partially substitute for the MYST Sas2 HAT in yeast telomeric position effect (TPE). Finally, we provide in vivo evidence that the acetyltransferase activity of Chm is required in these processes, since a variant protein mutated in the catalytic domain no longer rescues PEV modification, telomeric silencing of SAS2-deficient yeast cells, nor lethality of chm mutant flies. These findings emphasize the role of an acetyltransferase in gene silencing, which supports, according to the histone

Choline acetyltransferase (CAT) catalyzes the biosynthesis of acetylcholine according to the chemical equation: Acetyl-CoA + Choline in equilibrium Acetylcholine + CoA. To demonstrate the neuronal relationship of this enzyme, CAT activity was measured in hearts to which the extrinsic innervation was completely interrupted by extirpation of the heart from a donor animal and transplantation in a heterotopic position into the recipients abdominal cavity. After the animals were killed at 8 days, enzyme activity in the transplanted hearts was measured and compared with that of the recipient. Choline acetyltransferase activity decreased 98% in the right atrium of the transplanted denervated hearts, 94% in the SA node, 87% in the left atrium, 80% in the right ventricle, and about 50% in the interventricular septum and left ventricle. These data show that sectioning the extrinsic parasympathetic innervation to the heart results in variable decreases in CAT activity, a finding which confirms that CAT activity

The human p300/CBP-associating factor, PCAF, mediates transcriptional activation through its ability to acetylate nucleosomal histone substrates as well as transcriptional activators such as p53. We have determined the 2.3 A crystal structure of the histone acetyltransferase (HAT) domain of PCAF bound to coenzyme A. The structure reveals a central protein core associated with coenzyme A binding and a pronounced cleft that sits over the protein core and is flanked on opposite sides by the N- and C-terminal protein segments. A correlation of the structure with the extensive mutagenesis data for PCAF and the homologous yeast GCN5 protein implicates the cleft and the N- and C-terminal protein segments as playing an important role in histone substrate binding, and a glutamate residue in the protein core as playing an essential catalytic role. A structural comparison with the coenzyme-bound forms of the related N-acetyltransferases, HAT1 (yeast histone acetyltransferase 1) and SmAAT (Serratia ...

tGCN5 histone acetyltransferase: transcription regulator involved in release of inactive DNA from its packaging of histone proteins; amino acid sequence in first source; atomic coordinates in PDB 5GCN

Reversible acetylation of histone and nonhistone proteins plays pivotal role in cellular homeostasis. Dysfunction of histone acetyltransferases (HATs) leads to several diseases including cancer, neurodegenaration, asthma, diabetes, AIDS, and cardiac hypertrophy. We describe the synthesis and characterization of a set of p300-HAT-specific small-molecule inhibitors from a natural nonspecific HAT inhibitor, garcinol, which is highly toxic to cells. We show that the specific inhibitor selectively represses the p300-mediated acetylation of p53 in vivo. Furthermore, inhibition of p300-HAT down regulates several genes but significantly a few important genes are also upregulated. Remarkably, these inhibitors were found to be nontoxic to T cells, inhibit histone acetylation of HIV infected cells, and consequently inhibit the multiplication of HIV.. ...

Essential for RNA polymerase III to make a number of small nuclear and cytoplasmic RNAs, including 5S RNA, tRNA, and adenovirus-associated (VA) RNA of both cellular and viral origin. Has histone acetyltransferase activity (HAT) with unique specificity for free and nucleosomal H3. May cooperate with GTF3C5 in facilitating the recruitment of TFIIIB and RNA polymerase through direct interactions with BRF1, POLR3C and POLR3F. May be localized close to the A box.

In article ,31C894FB.1855 at odyssee.net,, dellaire at ODYSSEE.NET says... , ,I was wondering if the cDNA is out for the acetyl transferase gene for ,mammals.. mouse or human. I know the yeast homolog is cloned but the ,cDNA is not available yet I dont think (at least not through NCBI or ,Entrez). ,Has anyone worked with the yeast acetyl transferase? Youll have to be a bit more specific than acetyltransferase as there are quite a few of them. My own interest is/was arylamine N-acetyltransferases involved in xenobiotic metabolism and the sequences of the two human forms (and variants) and rabbit forms have been available for some time. What do you want acetylated? Bernard Bernard Murray, Ph.D. bernard at elsie.nci.nih.gov (National Cancer Institute, NIH, Bethesda MD, USA) If I knew what was going on Id really be indignant. -Crow T.
