The process of removing one or more phosphoric residues from a protein.

The process of removing one or more phosphoric (ester or anhydride) residues from a molecule.

The transfer, from NAD, of ADP-ribose to protein amino acids.

The alteration of the N-terminal amino acid residue in a protein.

The addition of an acetyl group to a non-terminal amino acid in a protein.

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

The addition of a sulfate group to a molecule.

An intracellular non-membrane-bounded organelle; a hollow structure made of protein, which usually has the form of a cylindrical tube closed by conical end caps. By regulating their relative gas vesicle content, aquatic microbes are able to perform vertical migrations.

The 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 addition of an alkyl group to a protein amino acid. Alkyl groups are derived from alkanes by removal of one hydrogen atom.

The covalent attachment of a methyl residue to one or more monomeric units in a polypeptide, polynucleotide, polysaccharide, or other biological macromolecule.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a gas vesicle. A gas vesicle is a hollow structure made of protein, which usually has the form of a cylindrical tube closed by conical end caps.

Any process that modulates an organism's tendency or ability to rise or float in a fluid medium such as water or air, often through the use of stored gases.

A complex that catalyzes the transfer of an acetyl group to the N-terminal residue of a protein acceptor molecule.

A conserved complex that catalyzes the transfer of an acetyl group to an N-terminal Ser, Ala, Gly, or Thr residue of a protein acceptor molecule. In Saccharomyces the complex includes Nat1p and Ard1p, and may contain additional proteins.

A conserved complex that catalyzes the transfer of an acetyl group to the N-terminal residue of a protein acceptor molecule that has a Met-Glu, Met-Asp, Met-Asn, or Met-Met N-terminus. In Saccharomyces the complex includes Nat3p and Mdm20p.

A conserved complex that catalyzes the transfer of an acetyl group to the N-terminal residue of a protein acceptor molecule that has a Met-Ile, Met-Leu, Met-Trp, or Met-Phe N-terminus. In Saccharomyces the complex includes Mak3p, Mak10p, and Mak31p.

Binding to L-ascorbic acid, (2R)-2-[(1S)-1,2-dihydroxyethyl]-4-hydroxy-5-oxo-2,5-dihydrofuran-3-olate; L-ascorbic acid is vitamin C and has co-factor and anti-oxidant activities in many species.
