NMR Structure(hide GO term definitions)
Chain A   (ESA1_YEAST | Q08649)
molecular function
    GO:0010485    H4 histone acetyltransferase activity    Catalysis of the reaction: acetyl-CoA + histone H4 = CoA + acetyl-histone H4.
    GO:0004402    histone acetyltransferase activity    Catalysis of the reaction: acetyl-CoA + histone = CoA + acetyl-histone.
    GO:0034212    peptide N-acetyltransferase activity    Catalysis of the acetylation of an amino acid residue of a peptide or protein, according to the reaction: acetyl-CoA + peptide = CoA + N-acetylpeptide.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
    GO:0016747    transferase activity, transferring acyl groups other than amino-acyl groups    Catalysis of the transfer of an acyl group, other than amino-acyl, from one compound (donor) to another (acceptor).
biological process
    GO:0006281    DNA repair    The process of restoring DNA after damage. Genomes are subject to damage by chemical and physical agents in the environment (e.g. UV and ionizing radiations, chemical mutagens, fungal and bacterial toxins, etc.) and by free radicals or alkylating agents endogenously generated in metabolism. DNA is also damaged because of errors during its replication. A variety of different DNA repair pathways have been reported that include direct reversal, base excision repair, nucleotide excision repair, photoreactivation, bypass, double-strand break repair pathway, and mismatch repair pathway.
    GO:0006354    DNA-templated transcription, elongation    The extension of an RNA molecule after transcription initiation and promoter clearance at a DNA-dependent RNA polymerase promoter by the addition of ribonucleotides catalyzed by an RNA polymerase.
    GO:0000183    chromatin silencing at rDNA    Repression of transcription of ribosomal DNA by altering the structure of chromatin.
    GO:0043967    histone H4 acetylation    The modification of histone H4 by the addition of an acetyl group.
    GO:0016573    histone acetylation    The modification of a histone by the addition of an acetyl group.
    GO:0001207    histone displacement    The removal of histones, including histone dimers, from nucleosomes within chromatin.
    GO:0018394    peptidyl-lysine acetylation    The acetylation of peptidyl-lysine.
    GO:0016239    positive regulation of macroautophagy    Any process, such as recognition of nutrient depletion, that activates or increases the rate of macroautophagy to bring cytosolic macromolecules to the vacuole/lysosome for degradation.
    GO:0032968    positive regulation of transcription elongation from RNA polymerase II promoter    Any process that activates or increases the frequency, rate or extent of transcription elongation, the extension of an RNA molecule after transcription initiation and promoter clearance by the addition of ribonucleotides, catalyzed by RNA polymerase II.
    GO:0051726    regulation of cell cycle    Any process that modulates the rate or extent of progression through the cell cycle.
    GO:0006357    regulation of transcription from RNA polymerase II promoter    Any process that modulates the frequency, rate or extent of transcription from an RNA polymerase II promoter.
    GO:0006355    regulation of transcription, DNA-templated    Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
    GO:0006351    transcription, DNA-templated    The cellular synthesis of RNA on a template of DNA.
cellular component
    GO:0035267    NuA4 histone acetyltransferase complex    A complex having histone acetylase activity on chromatin, as well as ATPase, DNA helicase and structural DNA binding activities. The complex is thought to be involved in double-strand DNA break repair. Subunits of the human complex include HTATIP/TIP60, TRRAP, RUVBL1, BUVBL2, beta-actin and BAF53/ACTL6A. In yeast, the complex has 13 subunits, including the catalytic subunit Esa1 (homologous to human Tip60).
    GO:0032777    Piccolo NuA4 histone acetyltransferase complex    A heterotrimeric H4/H2A histone acetyltransferase complex with a substrate preference of chromatin over free histones. It contains a subset of the proteins found in the larger NuA4 histone acetyltransferase complex; for example, the S. cerevisiae complex contains Esa1p, Yng2p, and Epl1p.
    GO:0000790    nuclear chromatin    The ordered and organized complex of DNA, protein, and sometimes RNA, that forms the chromosome in the nucleus.
    GO:0005724    nuclear telomeric heterochromatin    Heterochromatic regions of the chromosome found at the telomeres of a chromosome in the nucleus.
