*  Platelet-activating factor acetylhydrolase and transacetylase activities in human plasma low-density lipoprotein | Biochemical...
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 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.. ...

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). The deubiquitination module (DUBm) of candida SAGA comprises ...

*  Epigenetics - Wikipedia
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 ...

*  "Role for ADA/GCN5 products in antagonizing chromatin-mediated transcri" by Kerri Jeanne Pollard and Craig L. Peterson
The Saccharomyces cerevisiae SWI/SNF complex is a 2-MDa multimeric assembly that facilitates transcriptional enhancement by antagonizing chromatin-mediated transcriptional repression. We show here that mutations in ADA2, ADA3, and GCN5, which are believed to encode subunits of a nuclear histone acetyltransferase complex, cause phenotypes strikingly similar to that of swi/snf mutants. ADA2, ADA3, and GCN5 are required for full expression of all SWI/SNF-dependent genes tested, including HO, SUC2, INO1, and Ty elements. Furthermore, mutations in the SIN1 gene, which encodes a nonhistone chromatin component, or mutations in histone H3 or H4 partially alleviate the transcriptional defects caused by ada/gcn5 or swi/snf mutations. We also find that ada2 swi1, ada3 swi1, and gcn5 swi1 double mutants are inviable and that mutations in SIN1 allow viability of these double mutants. We have partially purified three chromatographically distinct GCN5-dependent acetyltransferase activities, and we show that these

*  HTATIP - Wikipedia
La histona acetiltransferasa KAT5 (HTATIP) es una enzima codificada en humanos por el gen kat5.[1]​[2]​ La proteína HTATIP pertenece a la familia MYST de histona acetiltransferasas (HATs) y fue originalmente aislada como una proteína de interacción con TAT de VIH-1. Las HATs juegan un importante papel en la regulación de la remodelación de la cromatina, de la transcripción y de otros procesos nucleares por acetilación de proteínas histonas y no histonas. Esta proteína es una histona actiltransferasa que actúa en la reparación del ADN y en procesos de apoptosis, y se piensa que juega un importante papel en la transducción de señales. Se han descrito numerosas variantes transcripcionales del gen que codifica esta enzima.[2]​ La proteína HTATIP ha demostrado ser capaz de interaccionar con: HDAC7A[3]​ FANCD2[4]​ CREB1[5]​ ETV6[6]​ Mdm2[7]​ Myc[8]​ BCL3[9]​ Receptor androgénico[10]​ Receptor de endotelina tipo A[11]​ PLA2G4A[12]​ Kamine J, Elangovan B, ...

The histone acetyltransferases (HAT) CBP and p300 are important coactivators favoring transcription. Their involvement in various pathologic processes has been extensively studied in the past (1). In fact, CBP and p300 are known as functional paralogues and their HAT domains show sequence identity of more than 90% (2). Both proteins are fundamental coactivators of a large number of transcription factors by remodeling chromatin. Moreover, p300 and CBP can bind not only to target proteins and regulate DNA binding affinity, transcriptional activation, protein-protein interactions, and stability of transcription factors but also to other cellular proteins by acetylation (3). For that reason, HATs are also named lysine acetyltransferases (KAT; ref. 4).. In cancer, the role of p300 and CBP is not clear and may depend on the physiologic background of the tumor. The fact that p300 is targeted by viral oncoproteins and is often found mutated or in a truncated form in breast, ...
