Enables the transfer of copper (Cu) ions from one side of a membrane to the other.

Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: ATP + H2O = ADP + phosphate, to directly drive the transport of ions across a membrane. The reaction is characterized by the transient formation of a high-energy aspartyl-phosphoryl-enzyme intermediate.

The assembly from its constituent parts of a type IV pilus.

A complex of proteins related to those involved in bacterial DNA conjugative transfer, that permits the transfer of DNA or proteins into the extracellular milieu or directly into host cells. In general the type IV complex forms a multisubunit cell-envelope-spanning structure composed of a secretion channel and often a pilus or other surface filament or protein(s).

The modification process that results in the conversion of glutamate charged on a tRNA(Gln) to glutaminyl-tRNA.

Catalysis of the reaction: R-CHOH-R' + NADP+ = R-CO-R' + NADPH + H+.

Catalysis of the reaction: acetyl-CoA + carnitine = (R)-O-acetylcarnitine + CoA.

Catalysis of the transfer of an acyl group to an oxygen atom on the carnitine molecule.

Catalysis of the reaction: palmitoyl-CoA + L-carnitine = CoA + L-palmitoylcarnitine.

Catalysis of the transfer of a palmitoyl group to an oxygen atom on the acceptor molecule.

Catalysis of the reaction: 2 hydrogen peroxide = O2 + 2 H2O.

Catalysis of the reaction: 2 L-dopa + O2 = 2 H2O + 2 L-dopaquinone. This reaction catalyzes exclusively the oxidation of catechols (i.e., o-diphenols) to the corresponding o-quinones.

Catalysis of the reaction: a cerebroside 3-sulfate + H2O = a cerebroside + sulfate.

Catalysis of the reaction: chitin + H2O = chitosan + acetate.

OBSOLETE. A small pore in the outer wall of a mycelial spore through which the germ tube exits upon germination. It can be apical or eccentric in its location.

The innermost of the major layers of the pollen grain wall which underlies the exine and borders the cytoplasm.

The part of a synapse that is part of the presynaptic cell.
