Catalysis of the reaction: acetyl-CoA + peptide = CoA + N-alpha-acetylpeptide. This reaction is the acetylation of the N-terminal amino acid residue of a peptide or protein.

Any process that activates or increases the frequency, rate or extent of barbed-end actin filament capping.

Any process that modulates the frequency, rate or extent of barbed-end actin filament capping.

Protein complex facilitating ATP-dependent cobalamin (vitamin B12) transport through inner cell membrane (periplasm to cytoplasm) in Gram-negative bacteria. In E. coli the system is composed of a periplasmic cobalamin-binding protein (BtuF), an integral membrane homodimer, BtuC, and a cytoplasmic ATP-binding homodimer BtuD.

A process of regulation of mRNA stability that is involved in a response to oxidative stress.

Any process that modulates the frequency, rate or extent of the assembly of actin filaments by the addition of actin monomers to a filament.

Any process that modulates the frequency, rate or extent of the disassembly of actin filaments by the removal of actin monomers from a filament.

Any process that stops, prevents or reduces the frequency, rate or extent of barbed-end actin filament capping.

Any process that activates or increases the frequency, rate or extent of actin polymerization.

Any process that activates or increases the frequency, rate or extent of actin depolymerization.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a disturbance in organismal or cellular homeostasis caused by a copper ion stimulus.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a disturbance in organismal or cellular homeostasis caused by a metal ion stimulus.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a copper ion stimulus.

A protein deubiquitination process in which a K27-linked ubiquitin chain, i.e. a polymer of ubiquitin formed by linkages between lysine residues at position 27 of the ubiquitin monomers, is removed from a protein.

A protein deubiquitination process in which a K33-linked ubiquitin chain, i.e. a polymer of ubiquitin formed by linkages between lysine residues at position 33 of the ubiquitin monomers, is removed from a protein.

Binding to damaged DNA containing single-strand breaks (SSBs).

Binding to damaged DNA.

Any process in which a protein is transported to, or maintained at, a region of a chromosome at which a DNA double-strand break has occurred.

Any process in which a protein is transported to, or maintained at, a specific location on a chromosome.
