The addition of an acetyl group to a protein amino acid. An acetyl group is CH3CO-, derived from acetic [ethanoic] acid.

N-terminal protein amino acid acetylation

The acetylation of the N-terminal amino acid of proteins.

The external part of the cell wall and/or cell membrane.

The removal of an acetyl group from a protein amino acid. An acetyl group is CH3CO-, derived from acetic [ethanoic] acid.

The addition of a sulfate group as an ester to a protein amino acid.

Cell recognition between cells, usually involving the formation of specialized cell junctions.

The posttranslational sulfation of peptidyl-tyrosine residues to form peptidyl-O4'-sulfo-L-tyrosine.

The addition of a methyl group to a protein amino acid. A methyl group is derived from methane by the removal of a hydrogen atom.

The process of coupling arginine to arginyl-tRNA, catalyzed by arginyl-tRNA synthetase. In tRNA aminoacylation, the amino acid is first activated by linkage to AMP and then transferred to either the 2'- or the 3'-hydroxyl group of the 3'-adenosine residue of the tRNA.

The process of coupling asparagine to asparaginyl-tRNA, catalyzed by asparaginyl-tRNA synthetase. In tRNA aminoacylation, the amino acid is first activated by linkage to AMP and then transferred to either the 2'- or the 3'-hydroxyl group of the 3'-adenosine residue of the tRNA.

The removal of amino group in the presence of water.

The process of coupling aspartate to aspartyl-tRNA, catalyzed by aspartyl-tRNA synthetase. In tRNA aminoacylation, the amino acid is first activated by linkage to AMP and then transferred to either the 2'- or the 3'-hydroxyl group of the 3'-adenosine residue of the tRNA.

The process of coupling cysteine to cysteinyl-tRNA, catalyzed by cysteinyl-tRNA synthetase. In tRNA aminoacylation, the amino acid is first activated by linkage to AMP and then transferred to either the 2'- or the 3'-hydroxyl group of the 3'-adenosine residue of the tRNA.

The process of coupling glutamate to glutamyl-tRNA, catalyzed by glutamyl-tRNA synthetase. In tRNA aminoacylation, the amino acid is first activated by linkage to AMP and then transferred to either the 2'- or the 3'-hydroxyl group of the 3'- adenosine residue of the tRNA.
